Pine Barrens Soil Horizons

Yesterday, I transplanted a small piece of Carex pensylvanica, Pennsylvania sedge, from my sister’s property in Ocean County, New Jersey. This species is common on her property.

She lives in the pinelands of New Jersey. The canopy is pine and oak. The duff layer – the natural “mulch” of dead plant material deposited on top of the soil – is composed of mostly pine needles, with some oak leaves.

Here’s a view of the clump I extracted.


And here’s the “back” view, where the blade of the spade I was using sliced through.

I only just realized I had a nice slice of the upper soil horizons.

The slats of the tabletop are 2″ wide. The entire depth of the soil slice is only about 3″, 4″ including the duff layer.

The white is fungal mycelium that has colonized the duff layer, starting the process of decomposition.

After I moved this clump from the table, I noticed tiny beetles, at least two different species, had clambered off. They fell through the slats before I could photograph them or otherwise observe them more closely for identification.

This small slice represents at least five different macro-species – pine, oak, sedge, and beetles – and one micro: the fungus. If we could somehow inventory all the micro-invertebrates and micro-organisms, there might be hundreds, or thousands, of species in this photo.

It’s tempting to think of species as singular “things,” to be contained in our cabinets of curiosities, our checklists, our collections. Any species is not any one thing, but a population, containing genetic diversity that slowly shifts and drifts across space and time. Each species is part of a larger whole, an unbounded fractal of complex relationships.

Yes, I grow many native plant species in my garden. For one reason, I can learn to recognize them. I never want to forget how artificial my construction is. However I may hone my garden, whatever beauty I can construct here, and pleasure I may offer from it, it doesn’t compare to the transcendence I experience of wild things in their natural habitats. All this diversity at home reminds me of how much more there is, still, in the world, and how important it is to protect it.

April 2015: Native Plants Planting Plan

2015-04-26 Update: Finally finished planting everything.


Took me most of the day to figure out where all of the 63 plants I received this week are going. Better late then never.

Bog Planters

Plant in the bog planters. I’ve only seen Iris versicolor, but never grown it. The other species are new to me.

  • Geum rivale, water avens
  • Iris prismatica, slender blue flag
  • Iris versicolor, blue flag
  • Mimulus alatus, winged monkey-flower
  • Mimulus ringens, square-stemmed monkey-flower

“Wetland” area

Planted where they can benefit from runoff from the garage, bog planters, and other containers. I’ve seen Caltha, but never grown it. The others are new to me.

  • Argentina anserina, Silverweed
  • Caltha palustris, marsh marigold
  • Ludwigia alternifolia, bushy seedbox
  • Menispermum canadense, Canada moonseed
  • Mitella diphylla, two-leaved mitrewort
  • Penthorum sedoides, ditch stonecrop
  • Scirpus cyperinus, common wool-grass
  • Scutellaria lateriflora, mad-dog skullcap
  • Woodwardia areolata, netted chainfern

Front Yard “Meadow”

This is sunny to partly sunny, dry to moist. Except for the Allium, of which – I’d forgotten – I’m already growing a cultivar, all these species are new to me.

  • Allium cernuum, nodding onion
  • Asclepias verticillata, whorled milkweed. Part of my effort to increase the number of milkweed species in my garden.
  • Chelone glabra, white turtlehead, planted at the shadier end of the border.
  • Helianthus decapetalus, ten-petal sunflower
  • Liatris scariosa, Northern blazing-star
  • Oclemena acuminata, whorled wood aster
  • Parthenium integrifolium, wild quinine
  • Penstemon hirsutus, northeastern beard-tongue
  • Pycnanthemum incanum, hoary mountain-mint. This and the next species are relatives of the P. muticum, clustered mountain-mint, which is abundant in my garden and gets more pollinator visitors than any other plant. I’m growing P. virginianum elsewhere. I want to compare these species, both to be able to identify them, and to see if there are any differences in the number or species of pollinators they attract.
  • Pycnanthemum verticillata, whorled mountain-mint
  • Symphyotrichum pilosum pilosum, hairy white oldfield aster
  • Symphyotrichum prenanthoides, crookedstem aster
  • Viola palmata, early blue violet
  • Zizia aptera, heartleaf golden alexanders. Relative of the Z. aurea I already have, and which is seeding itself in my garden. I’ll also be transplanting some of these volunteers to the front yard. I want more plants from the Apiaceae as hosts for Eastern black swallowtails, in the hopes they’ll leave more of our parsley for us.

Backyard “Woodland”

Small things, planted by the Gardener’s Nook so I can keep a close eye on them this year. Some of these are favorites I’d planted in the native plant area of my first garden in the East Village.

  • Actaea pachypoda, white baneberry
  • Actaea rubra, red baneberry
  • Anemone acutiloba (Hepatica acutiloba)
  • Dicentra canadensis, squirrel corn
  • Dicentra cucullaria, dutchman’s breeches
  • Dodecathon meadia, shooting star, white- and pink-flowering forms
  • Hydrastis canadense, goldenleaf
  • Jeffersonia diphylla, twinleaf
  • Sanguinaria canadensis, bloodroot
  • Thalictrum dioicum, early meadow-rue
  • Viola affinis, sand violet
  • Viola labradorica, Labrador violet
  • Waldsteinia fragarioides, Appalachian barren strawberry

Planted in various other locations in the backyard.

  • Agrimonia striata, woodland agrimony
  • Anemone virginiana, Virginia anemone
  • Argentina anserina, silverweed
  • Arisaema draconitum, green dragon
  • Eurybia divaricata, white wood aster
  • Geum aleppicum, yellow avens
  • Geum canadense, white avens
  • Hydrophyllum virginianum, waterleaf. This turns out to be a duplicate. I thought I had killed the specimen I bought a few years, but it had just moved from its planted spot.
  • Osmunda claytoniana, interrupted fern. A favorite of mine from my first garden in the East Village.
  • Phlox divaricata ‘Blue Moon’, woodland phlox
  • Rudbeckia laciniata, cut-leaved coneflower. Another accidental duplicate. I’ve got one in the front I planted last year that I’d forgotten about.
  • Symphyotrichum laeve, smooth aster
  • Symphyotrichum novi-belgii, New York aster

Planted in the backyard along the neighbor’s fence where they can fill in and provide background for other plants in the foreground.

  • Carex lupulina, hop sedge
  • Thelypteris palustris, marsh fern

I’ve also got a few more new sedges. I planted these together near the front of the north/serviceberry bed so I can observe them closely and learn how to identify them.

  • Carex appalachica, Appalachian sedge
  • Carex grayi, Gray’s sedge
  • Carex rosea, rosy sedge, curly-styled wood sedge
  • Carex squarrosa, squarrose sedge, narrow-leaved cattail sedge

Finally, two new vines.

  • Dioscorea villosa, wild yam. Planted on our neighbor’s fence along the driveway, near the Clematis virginiana.
  • Vitis aestivalis, summer grape. Planted on an arbor between the two vegetable beds along the driveway. Don’t know if we’ll get actual grapes from this or not.

Invasive Plant Profile: Chelidonium majus, Celandine, Greater Celandine

Revised 2015-02-23: This was one of my earliest blog posts, first published in June 2006. I’ve overhauled it to 1) meet my current technical standards, and 2) improve the content based on the latest available information.



Chelidonium majus, Celandine or Greater Celandine, is a biennial (blooming the second year) herbaceous plant in the Papaveraceae, the Poppy family. It is native to Eurasia. It’s the only species in the genus.

It’s invasive outside its native range, and widespread across eastern North America. It emerges early in the Spring, before our native wildflowers emerge, and grows quickly to about 2 feet. That’s one of the clues to identification. It’s also one of the reasons why it’s so disruptive. The rapid early growth crowds and shades out native Spring ephemerals.

Greater celandine is one of the first weeds I identified when we bought our home in 2005 and I started the current gardens. Here’s my collection of photos from the garden’s second year, in 2006, highlighting the characteristics that help to identify this plant. The photos (click for embiggerization) show:

  1. Full view of plants, showing growth habit, bloom, and ripening seedpods on the same plants. The plants in this picture are about two feet tall. In the middle and lower left of the picture, you can see the leaves of Hemerocallis (Daylilies) just peeking out from under the Chelidonium.
  2. Broken stem with orange sap. You can also see a small flower bud in the leaf axil to the left.
  3. Detail of flower. Notice the 4 petals, clustered stamens, and central pistil with white stigma.
  4. Detail of ripening seedpod. These seedpods are what made me think at first that this plant was in the Brassicaceae (or, if you’re old-school like me, the Cruciferae), the Mustard family. It’s actually in the Papaveraceae (Poppy family).

At the time these pictures were taken in early June, these plants had already been blooming for two months. After I took these pictures, I removed all the plants (and there were many more than are visible in these photos!).

Part of coming to any new garden is learning the weeds. There are always new ones I’ve never encountered before, or that I recognize but am not familiar with. Learning what they are, how invasive or weedy they are, their lifecycle, how they propagate, and so on helps me prioritize their removal and monitor for their return.

For example, Chelidonium is a biennial. So pulling up visible plants before their seeds ripen and disperse kills this year’s generation and the generation two years from now. I might overlook next year’s generation this spring, but I’ll get them next year. The plants are shallowly rooted. By grabbing the plant at the base of the leaves, I can remove the whole thing easily, roots and all.

Chelidonium‘s seeds are dispersed by ants. They’re likely to show up next year close to where they were this year, but not necessarily in the same place. In addition, the soil probably has a reservoir of seeds from the years the garden was neglected. If I disturb the soil, or transplant plants from one part of the yard to another, they could show up in new places. By pulling the plants when they emerge in the spring, and keeping an eye out for their emergence in new places in the garden, I can easily control them. It will take a few years of vigilant weeding to eliminate them completely.

Note that, at a quick glance, this plant can be confused with the native* wildflower Stylophorum diphyllum, celandine-poppy. They’re very similar. Both are in the Papaveraceae, bloom in the spring with four-petaled yellow flowers, have lobed foliage and bright orange/yellow sap, and are about the same height. I find the seedpods the easiest way to distinguish them. The flowers of Stylophorum lack the prominent tall central pistil of Chelidonium, and the stamens form more of a “boss” around the center of the flower, not so obviously grouped in four clusters.

* Stylophorum isn’t native, or present, in New York. But it is native to eastern North America.

An Elegy for Biophilia

I was moved to write this by a short missive from Reverend Billy:

When I go to pray, which is sometimes difficult being so without any god, I think of that time in my life, because the natural world was overwhelming the god that my family insisted was all-powerful and all-knowing. Creation was overwhelming the Creator and it came in the form of undulating prairie grasses.

I was raised in temperate and tropical suburbia. Even in those landscapes, the woods in the backyard, or the palmetto swamp at the end of the road or the canal, drew me to them. They were my expanse. Yet, compared to what existed before the forests were razed and the swamps drained, the landscapes of my childhood were impoverished.

The shifting baseline degrades further. More than half the world now lives in cities, with less ready access to nature than ever before in the history of our species. Biodiversity is an environmental justice issue.

I’ve chosen to live my adult live in a city. Even here, those childhood experiences guide me. I garden because it connects me to nature, it nourishes me. The beauty I invite is not of my making, but larger, deeper, and older than I can comprehend.

I believe it everyone’s right to have that connection for themselves. Not only a right, but necessary. Not only for our own health, but to have some hope for the future health of our planet.

That hope, however impoverished, is what keeps me going.

Pollinator Gardens, for Schools and Others

I got a query from a reader:

I’m working on a school garden project and we’d like to develop a pollinator garden in several raised beds. Can you recommend some native plants that we should have in our garden? Ideally we’d like to have some perennials and maybe a few anchor bushes. Are there any flowers that we might be able to start inside this spring then transplant? Also, because the students will be observing the pollinators, butterfly attracting plants are preferable to the teachers.

Whole books have been written on this topic, but here are some quick thoughts and references for further research.

Design Notes

  • How much space is available for the garden? That will determine how many shrubs could be accommodated. Layout the woody plants first, then plan blocks of plants through the rest of the beds.
  • Is it sunny? Shady? Mixed? Trees nearby? That will determine the types of plants that can be grown. Pollinators are more active in the sun, but you can still get plenty of action in shadier gardens. Just make the most of the sun and light you get throughout the day.
  • How will it be watered while getting established? Who will water it? What happens during the summer while school is out? After the first year, once established with the right plant selections, watering needs should be minimal.
  • Are the raised beds already established, or will they be filled with soil? Many “pollinator” plants fare languish in the rich soils prepared for the vegetables and edibles more typically grown in school gardens, and would prefer ordinary, even “poor,” soils.
  • Plant multiples of the same plants in groups and patches, to make them easier for pollinators to find. It also provides a more continuous supply of nectar: if one flower or plant runs dry, another in the same patch can provide.
  • See more about what to plant, below.

Plan for Pollinators

Pollinators visit flowers for two main reasons: nectar and pollen. We want to create habitat, not just a buffet. Plan to address the four basic needs: water, food, shelter, and a place to raise young. Host plants are just as important as flowers.

Even if we limit consideration to insect pollinators, there are many different kinds, including bees, wasps, flies, beetles, butterflies, and moths. Everyone wants butterflies, the divas of the garden. Some are squeamish about bees and wasps, but they really don’t bother people. Any flowers you grow will attract them, so they’re part of the garden already.

Bees, of course, are all-around the most effective pollinators. But not just honeybees. There are scores of native bee species happy to take up residence in a garden.

You can setup nesting boxes for native mason bees and carpenter bees. They’re fascinating to watch, and you can see how the nest tubes get occupied over time.

Monarch butterflies are in steep decline and need our help. Milkweeds are their preferred host plants, so planting milkweeds is the best thing you can do to help monarchs. Several milkweed species are native to NYC. Many other pollinators are attracted to the flowers, as well.

Plant Native

When planting for pollinators, the most important factors are:
  • To get the greatest number and diversity of pollinators, choose plants that have clusters of many small flowers, such as plants in the Asteraceae (asters, daisies, sunflowers, goldenrods, etc) and Lamiaceae (mints) families.
  • Include plants that bloom at different times of the year – especially very early and later in the year, when flowers are scarce – to provide a continuous supply of food for both adults and their young.
  • Differences in flower size and structure affect which pollinators they can support.
  • Insect-host plant associations can be very specific. Plants from different families support different species. So diversify the plant families you grow.
  • Plant as many different species as your space can accommodate.
  • Don’t forget to use the vertical space: include plants that grow taller and shorter. 
  • Plant in masses and blocks. Pollinators recognize they’re more likely to find pollen and nectar when several different plants, with many different flowers blooming at different stages, are available to choose from.
  • The best plants for pollinators are native to the region, and – as much as possible – from local stock. This is true for both nectar and host plants. Prefer native species over non-native, straight species over cultivars, propagated from local populations over more distant ones. 

I adapted this chart from published results of the Pollinator Plant Trial (PDF, 3 pp) at Penn State Southeast Agricultural Research and Extension Center (SEAREC)

My authority for “What’s native?” in my region is the NY Flora Atlas. You sometimes have to watch out for changes in nomenclature, but it’s an excellent resource. Resources for our adjacent states are the Native Plant Society of New Jersey and the Connecticut Botanical Society.

Your best bet for obtaining plants propagated from local stock is to work with nurseries based near you that specialize in native plants. In my area, for starting native plants from seed I recommend Toadshade Wildflower Farm located nearby in New Jersey. They have an astonishing range of native plants available, and seed for many of them. They’re passionate, experienced, and know their plants.

FAQ: Where do you get your plants?

[First in what I hope will be a series of Frequently Asked Questions, FAQs. If you have any questions for me, I invite you to leave a comment, or ping me on Twitter.]

Question: Where do you get your plants?

Answer (short)

I specialize in gardening with native plants. I get my plants from a variety of sources, including mail-order nurseries, local and regional nurseries, annual plant sales, and neighborhood plant exchanges. My Native Plants page has a list of Retail Sources of Native Plants in and around New York City, extending to New England and the Mid-Atlantic.

Answer (longer)

I’ve been gardening in New York City for over three decades, since 1981 or thereabouts in the East Village, since 1992 in Brooklyn. Each garden provided its own challenges, and lessons. The plants I seek out, and where I get them, has changed a lot over time.

The first 20 years: Shade, Concrete, and Invasives

The first garden, in the East Village, was surrounded by adjacent buildings and overtopped by two large Ailanthus altissima trees (the “tree that grew in Brooklyn”). There I learned, by necessity, about gardening in shade. Garden , in Park Slope, was nearly all concrete; there I learned to garden in containers. Garden , also in Park Slope, had been somewhat neglected; weeds and invasive plants, including Fallopia japonica, Japanese Knotweed, were the lessons there.

I’ve always included native plants in my gardens. In the East Village garden, I planted a small wildflower area that was, perhaps, my favorite spot. I added a small wildflower plot to the 3rd garden, as well. Out of necessity, most of these were cultivars, the only “native plants” commercially available at the time. I divided many of them and brought them to my current garden.

The 4th Garden

This Spring will be 10 years since we closed on our current home, and I started work on my fourth garden in New York City. Here the lessons have been about rehabilitation, and healing the land, if only in my small pocket of it.

The backyard was the initial focus of my efforts. My goal here was to recreate a shady woodland garden, populated with native woodland plants. Four years in, it was my design subject for the Urban Garden Design class I took at Brooklyn Botanic Garden.
Final rendering, backyard garden design

10 years ago, the backyard was a wasteland of dust and scraggly grass, shaded by multiple Norway maples.
Backyard, view away from garage, May 2005

The first month, I removed four trees from this small space. Over time, the remaining three trees failed and had to be removed. After 10 years, I’m still working on building up the soil to meet the needs of more specialized woodland plants. But I’ve been largely successful in rehabilitating this space.

Similarly, the front yard was, at best, barren: lawn and a few canonical evergreen shrubs.
Front Garden, April 2005

Our house was built in 1900. In keeping with the historical nature of our home, and the neighborhood, initially I focused on heirloom plants in the front garden.
The Front Garden

As my knowledge of and experience with gardening with native plants grew, I expanded the scope of their planting to include all areas around the house. The loss of our neighbor’s street tree a few years ago to Hurricane Irene opened up – literally – the opportunity to grow more sun-loving species in the front yard. I started taking out the front lawn two years ago, gradually replacing it with a mixed wildflower meadow. The original lawn has been reduced to a less than a third of its original extent.
Morning Glory: The Front Garden this morning

Most recently, I’ve narrowed my plant acquisitions further. My most treasured plants in my gardens are local ecotypes, those that have been propagated – responsibly – from local wild populations. There are two regional plant sales where these are available, both organized by regional preservation groups: the Long Island Native Plant Initiative, and the Pinelands Preservation Alliance. These are currently my preferred sources for plants.
I have arrived! LINPI Plant Sale

It’s my hope that more retail sources for local ecotypes will become available to urban gardeners. I recommend that gardeners who want to explore gardening with native plants choose straight species, not cultivars, from local growers, who are more likely to be growing plants propagated originally from local stock.

The Sun stands still

This season’s solstice occurs at 11:03 UTC, 6:03 Eastern Time. It’s winter in the northern hemipshere, summer in the southern.

Illumination of Earth by Sun at the southern solstice.
Etymology: Latin solstitium (sol “sun” + stitium, from sistere “to stand still”)

The name is derived from the Latin sol (sun) and sistere (to stand still), because at the solstices, the Sun stands still in declination; that is, its apparent movement north or south comes to a standstill.
Solstice, Wikipedia

It’s clearly winter here. The past few days the high temperature has hovered around freezing, and skies have been overcast. Gray, cold days. There seems to be little light in the world at large, these days. Sometimes it’s enough to just hold out for warmer, greener days.

Extinct Plants of northern North America

Updated 2014-12-22: Added years of extinction, where known. Started section for Extinct in the Wild (IUCN Red List code EW).


I’m limiting this list for two reasons:

  1. Restricting this list geographically is in keeping with my specialization in plants native to northeastern North America.
  2. There are many more tropical plants, and plant extinctions, than I can manage; for example, Cuba alone has lost more plant species than I’ve listed on this blog post. 

If you have additions to this list, please let me know, and provide a link which I can research.

  • Astilbe crenatiloba, Roan Mountain false goat’s beard, Roan Mountain, Tennessee, 1885
  • Narthecium montanum, Appalachian Yellow Asphodel, East Flat Rock Bog, Henderson County, North Carolina, before 2004?
  • Neomacounia nitida, Macoun’s shining moss, Belleville, Ontario, 1864
  • Orbexilum macrophyllum, bigleaf scurfpea, Polk County, North Carolina, 1899
  • Orbexilum stipulatum, large-stipule leather-root, Falls-of-the-Ohio scurfpea, Rock Island, Falls of the Ohio, KY, 1881
  • Thismia americana, banded trinity, Lake Calumet, IL, 1916

Extinct in the wild

Extinct versus Extirpated

I often come across misuse of the word “extinct,” as in: native plant extinct in New York City. “Extinct” means globally extinct. No living specimens exist anywhere in the world, not even in cultivation. “Extirpated” means locally extinct, while the species persists in other populations outside of the study area. To correct the above example: extirpated in New York City. Any regional Flora lists many extirpated species. When a species is known only from one original or remaining population, as those listed above were, loss of that population means extinction for the species. In this case, extirpation and extinction are the same thing. Another category might be “extinct in the wild” when the species still exists under cultivation, like an animal in a zoo. A famous example of this is Franklinia alatamaha.
