Garden Deeper

Posted on 2015-05-09 by admin

I had a visceral (in a good way) reaction to Adrian Higgins’ writeup of a visit, with Claudia West, to Shenk’s Ferry Wildflower Preserve.

I think I’ll adopt “ecological horticulturist” to describe my own approach to gardening. Whether you specialize in gardening with native plants, as I do, or prefer to grow plants from around the world, studying their native habitats is, in my experience, the best way to learn how to grow them in a garden.

That doesn’t mean you have to recreate the conditions exactly. In many cases, this is impossible, anyway. The native Aquilegia canadensis, eastern red columbine, thrives in the crumbling mortar of my front steps; this location recreates some aspects of the face of a limestone cliff where I saw, decades ago, a huge colony of them in full bloom.

This is why I’m trying to go on more botanical walks and hikes. Like many, if not most, gardeners, I’ve never seen most of the plants I grow in the wild. I visited Hempstead Plains for the first time in August 2013.

That inspired me last year to remove most of the remaining lawn in the front yard and approach it as a meadow, instead.

Rain gardens and rock gardens are both examples of creating gardens to grow plants requiring specific conditions, and to meet human needs. But we don’t need to go to so much trouble. For all the “problem areas” in our gardens, there are plants that want nearly exactly those conditions. We need only think like a plant to see these as opportunities, and embrace the habitats waiting to emerge.

Patent Lies: What’s “Native”? And What’s Not.

Posted on 2012-05-15 by admin

Echinacea pallida, Pale Coneflower, growing in my urban backyard native plant garden.

I was appalled to see the National Wildlife Federation publish on their Web site, without qualification or counter-point, a press piece by the “Brand Manager for American Beauties Native Plants.” (Appalled, but unfortunately, not shocked, given NWF’s mishandling of their Monsanto-Scotts-MiracleGro sell-out, and their ham-handed retraction only in the face of public outrage and opposition.)

The Brand Manager’s puff piece includes this statement:

At American Beauties Native Plants, we take a slightly broader view in our definition of native plants–we include cultivars. A cultivar is a plant that has been selected and cultivated because of some unique quality, such as disease resistance, cold hardiness, height, flower form or color. Sometimes interesting varieties are found in nature and brought into cultivation making them cultivated varieties or cultivars. In my years as a research horticulturist I observed pollinators, birds and other wildlife interacting freely with cultivated plants.

This paragraph is immediately followed by a photograph of “[Echinacea] ‘Tiki Torch’ is a hybrid of Echinacea paradoxa and a cultivar of Echinacea purpurea.”

A cultivar is a vegetatively propagated selection – a clone – of an individual from a population. But a hybrid is not a cultivar. More than that, ‘Tiki Torch’ is a patented plant. By definition, anything that is patented must be man-made, NOT natural, not native. One cannot obtain a patent on something that occurs naturally in the wild, even if you select it, propagate, and promote it as a cultivar. American Beauties greenwashing “native” with so broad a brush that they include patented plants is deceptive marketing. NWF blindly supporting such an association by publishing it unchallenged on their Web site is, at best, cluelessness.

In my urban backyard native plant garden, I grow plants from a range of sources, including cultivars, unnamed straight species of unknown geographic origins, and – my most-prized specimens – local ecotypes propagated by the Greenbelt Native Plant Center from wild populations in and around New York City. I also grow in container a beautiful specimen of the patented Heuchera ‘Caramel’ in this (otherwise) native plant garden. I use it to illustrate what is NOT native.

Gardening with the Hymenoptera (and yet not)

Posted on 2011-08-01 by admin

One of the great pleasures of gardening is observing the activity the garden invites. I can lay out the welcome mat, and set the table, but the guests decide whether or not the invitation is enticing enough to stop by for a drink, a meal, or to raise a family. While charismatic megafauna such as birds and mammals are entertaining, the most common and endlessly diverse visitors are insects.

The Hymenoptera includes bees, wasps, and ants. Although my garden also provides amply for ants, we’ll stick with the bees and wasps today. Following are some of the few portaits I’ve been able to capture of the many visitors to my gardens. The pollinator magnet, Pycnanthemum, Mountain-mint, in the Lamiaceae, provides the stage for many of these photos. I’m always amazed at the variety and abundance of insect activity it attracts when blooming.

Multiple pollinators on Pycnanthemum

Bees

There are over 250 species of bees native to New York City alone. I’m still learning to identify just a handful of the dozens of species that frequent my garden.

My current favorite is the bejeweled Agapostemon, Jade Bee

Bombus impatiens, Common Eastern Bumblebee, on Monarda fistulosa

Coelioxys, Cuckoo Bee. I think I’ve got several species from the genus visiting my garden, but I’ve yet to get identification for the others. These are in the Megachilidae, the Leaf-cutter and Mason Bee family. Bees in this family typically carry pollen on hairs beneath their abdomens, instead of in pollen baskets on their legs. You can see this bee isn’t carrying any pollen; it doesn’t even have the hairs beneath its abdomen to do so. It doesn’t need to, because it takes over the pollen-provisioned nests of other leaf-cutter bees for its own young.

Wasps

Bicyrtes quadrifasciatus

Euodynerus hidalgo boreoorientalis, Potter/Mason Wasp, Eastern subspecies

Sphex ichneumoneus, Great Golden Digger Wasp

Mimics

Along with the Hymenoptera come the mimic flies. Many of the seeming bees and wasps, seen from a distance, turn out to be flies on closer inspection. In “the field,” i.e.: my garden, there are two features that provide quick distinction between the two familes:

Antennae: Flies have short, clublike antenna, like feelers, in the center of the face, between the eyes. Bees and wasps have long, segmented antenna arising higher up on the face, almost from the top of the head
Eyes: Flies’ compound eyes are huge, covering nearly all of their face. Bees and wasps have compound eyes that wrap partially along the sides of their heads.

The feet are also different, but I usually don’t notice those until I’m browsing and culling my shots. Finally, bees and wasps have four wings, while flies only have two – Di-ptera, two-winged.

The Syrphidae/Flower-Fly family hosts countless mimics of bees and wasps.

Eristalis arbustorum on Hydrangea

Eristalis transversa, Transverse Flower Fly

Their tactics of mimicry are not limited to patterns and colors. Many species have evolved body modifications to mimic even the shapes of wasps and bees.

Syritta pipiens provides a good example of this. This is the most wasp-like fly I’ve found yet in my garden, though more extreme mimics exist. Glimpsed from behind as it moves quickly over the flowers, it could easily be mistaken for a tiny wasp.

Viewed from the side, or the front, Syritta is more obviously a fly, not a wasp, and a dedicated mimic.

Toxomerus geminatus sports a radically flattened abdomen. This seems to be an adaptation to present a wider area from above, as a predator might view it, for displaying its mimicry, while preserving a smaller volume and keeping weight down.

I wonder what they are mimicing? Might some of these mimics mirror actual target species, not just general “bee-ness” or “wasp-ness”? If so, I would expect to find both the mimic and subject in the same range, and exhibit the same phenology. For example, Toxomerus bears a resemblance to Agapostemon at a quick glance.

Photographing Insect Activity

This is my setup for doing live insect macro photography “in the wild,” i.e.: in my garden. The lens is a specialized macro lens that allows for an extremely close focusing distance, though I’m not taking advantage of it in this example. I target some flowers with lots of insect activity, in this case, a local ecotype of Monarda fistulosa, in the Lamiaceae, the Mint Family. Then I wait for insects to visit the flowers, within range of the camera.

I use the tripod handle to pivot up and down; it turns side-to-side easily. Ease of rapid movement with stability is critical, as the insect subjects move rapidly over each inflorescence, and from bloom to bloom. Still, the tripod only steadies my own shaky hands. The insects, of course, are moving, but so are the plants, which sway with the slightest breezes. A fast auto-focus helps; a quick hand is still needed when automation fails.

The mobility allows me to track a single insect as it moves around, and capture different shots, and perspectives, on the same individual. This is critical for identification, since I don’t know until later what the key features to look for might be. It’s often some tiny detail, only revealed from some obscure angle, that distinguishes the species.

My subjects, while largely oblivious to my actions, are not cooperative. I have to shoot hundreds of photos to get a few good shots that are in focus, free of motion blur, and have enough of the right details to identify the species, or at least narrow down to the family. This was never possible, or at least not economically feasible, before digital photography.

The bug geeks at BugGuide are awesome. Only through their generous sharing of knowledge and expertise have I been able to identify my little visitors. They cover the United States and Canada.

The international Xerces Society for Invertebrate Conservation has lots of information about gardening – and farming – with insects in mind, especially native bees. Their book, Attracting Native Pollinators: Protecting North America’s Bees and Butterflies, is outstanding.

Shedd Aquarium, Chicago

Posted on 2009-06-04 by admin

I got to Chicago early last week, ahead of the Chicago Spring Fling 2009 (CSF) weekend meetup of garden bloggers from across the country, so I could do a little touristy stuff. I didn’t get out as much as I had planned; mostly, I corrected my sleep deprivation. But I did get to go to the Shedd Aquarium.

When I was a boy, I lived in Florida for six years. That period of my childhood secured many of the interests that sustain me today, including photography, cosmology and space exploration, general natural history, and oceanography. I’ve lived my entire life no more than 20 miles from the Atlantic Ocean, and most of it less than 5 miles. If you had asked me, when I was 10 or 11 years old, what I wanted to be when I grew up, I would have responded: “A neurosurgeon, or a marine biologist.” (Yes, I have always been a geek, and proud of it.)

So, when I travel, I try to make a pilgrimage to whatever oceanographic attractions area nearby. Chicago’s Shedd Aquarium has been on my list to see. So it was easy to make that my first (and, it turned out, only) side-trip during CSF.

I didn’t know that much of what I saw was brand new. I also didn’t anticipate that, by mid-morning, I would be jostling for viewing space with thousands of school-children of all ages. I would have stayed longer, but I needed to eat. The line for the cafeteria went down the exhibit hall, so I had to leave earlier than I wanted to forage elsewhere.

December 8, Red Hook: Observing the Edge

Posted on 2007-11-30 by admin

This looks interesting:

Brooklynites know better than anyone the havoc that development can wreak on a habitat. So on Saturday, Dec. 8, the Kentler International Drawing Space in Red Hook will host an artist’s talk on “Observing the Edge,” the gallery’s current show, which features works on paper relating to flora and fauna with habitats threatened by progressive development.

… anyone who has seen plants, or any other living creatures, displaced by development will surely want to take notice.
– Cutting ‘Edge’, Daniel Goldberg, The Brooklyn Paper

(Note: The Brooklyn Paper gave the date incorrectly as 12/4.)

Sidewalk Skull

Posted on 2007-09-28 by admin

Tuesday morning I detoured slightly from my usual work commute routine to pay a visit to 251 East 19th Street. Along the way I found the item above, sitting in the middle of the sidewalk, as if it had been placed there.

I don’t know what it is, or was. I’m thinking raccoon, maybe opposum? Anyone out there able to provide an id?

This is the sort of found treasure I would normally snatch up and take home, to Blog Widow’s chagrin. Except that I was on my way to work, not home, and running late at that. Oh, and because it still had stuff on it; looks like remnants of skin on the right cheek. And me without a baggy to put it in.

I also didn’t have the foresight to whip out my ruler and place it alongside for scale. (Yes, I always carry a collapsible ruler in my bag.) It was a medium-sized skull, as skulls go. Bigger than a cat or a squirrel. Bigger than my fist, slightly smaller than my hand with fingers extended. Could have been a small dog, I guess.

The large eye orbits make me think it’s a nocturnal animal. The nasal ridges are also interesting. Whatever it was, it had a good nose.

Exploring Biophilia Through a USB Microscope

I’m in North Carolina this week, visiting my parents with my sister and nieces. It’s a confusing time, with both my nieces and parents demanding both my sister’s and my attention. “Which imaginary friend do you want to help me feed?” “Did I show you this?” So I welcome activities which can engage everyone, including me.

For this visit, my father bought an inexpensive USB microscope. I’ve been thinking about getting one of these myself, so I welcomed the opportunity to play around with one. It also turned an otherwise ordinary trip through the backyard with the nieces into an expedition. We collected samples – “specimens” – along the way, for examination under the microscope. Here are some of the highlights.

Nurtured by our parents, Both my sister and I have a life-long love of nature, and she has clearly nurtured the same in her children. My nieces picked out all these samples. They identified, and I gathered many of the specimens (there was poison ivy about). In a half-hour expedition, we collected about 20 samples, most of which went under the microscope. Much of that half-hour was taken up by observing the wildlife: electric blue damselflies, swallowtail butterflies, a frog, fish, a cardinal, and a rabbit. My nieces each carried their own binoculars. They’re 7 and 8 years old.

All the images are snapshots at 10X magnification. This microscope also offers 60X and 200X, but the controls are mushy and it’s difficult to hold an image in the narrow field of focus. The software is intuitive; my nieces figured out the controls before I did! My nieces did most of the manipulation of framing and lighting for the images above. I’ve credited the photos accordingly above. It took me some exploration to figure out how to capture an image and export it to a JPEG for upload. I did some tweaks for image capture, and some post-processing for shadows and contrast.

They’re brilliant, sometimes scary-smart, children. It’s a privilege to share and explore the world with them.

Happy Tercentenary Birthday, Carolus Linnaeus

Reproduction of a painting by Alexander Roslin in 1775. The original painting can be viewed at the Royal Science Academy of Sweden (Kungliga vetenskapsakademin).

Carolus Linnaeus, also known after his ennoblement as Carl von Linné, (May 23, 1707 – January 10, 1778), was a Swedish botanist, physician and zoologist who laid the foundations for the modern scheme of nomenclature. He is known as the “father of modern taxonomy.” He is also considered one of the fathers of modern ecology (see History of ecology).

Taxonomists, in almost any biological field, have heard of Carolus Linnaeus. His prime contribution was to establish conventions for the naming of living organisms that became universally accepted in the scientific world–the work of Linnaeus represents the starting point of binomial nomenclature. In addition Linnaeus developed, during the great 18th century expansion of natural history knowledge, what became known as the Linnaean taxonomy; the system of scientific classification now widely used in the biological sciences.

The Linnaean system classified nature within a hierarchy, starting with three kingdoms. Kingdoms were divided into Classes and they, in turn, into Orders, which were divided into Genera (singular: genus), which were divided into Species (singular: species). Below the rank of species he sometimes recognized taxa of a lower (unnamed) rank (for plants these are now called “varieties”).

… While the underlying details concerning what are considered to be scientifically valid ‘observable characteristics’ has changed with expanding knowledge (for example, DNA sequencing, unavailable in Linnaeus’ time, has proven to be a tool of considerable utility for classifying living organisms and establishing their relationships to each other), the fundamental principle remains sound.

Of course, any tool can be used against others.

Linnaeus was also a pioneer in defining the concept of race as applied to humans. Within Homo sapiens he proposed four taxa of a lower (unnamed) rank. These categories were Americanus, Asiaticus, Africanus and Europeanus. They were based on place of origin at first, and later on skin colour. Each race had certain characteristics that he considered endemic to individuals belonging to it. Native Americans were reddish, stubborn and easily angered. Africans were black, relaxed and negligent. Asians were sallow, avaricious and easily distracted. Europeans were white, gentle and inventive. Linnaeus’s races were clearly skewed in favour of Europeans. Over time, this classification led to a racial hierarchy, in which Europeans were at the top. Members of many European countries used the classification scheme to validate their conquering or subjugation of members of the “lower” races.
