Shrubs and Smaller Trees
- Allegheny Serviceberry
- American Hornbeam
- American Persimmon
- American Plum
- Eastern Redbud
- Elderberry
- Flowering Dogwood
- Highbush Blueberry

iNaturalist Workshops at GrowTogether, 4/22 & 4/23

It’s a busy season for me this Spring! NEXT WEEK is New York City NYC’s GreenThumb community gardening program annual conference, known as GrowTogether:
Part 2 of the GreenThumb GrowTogether conference will be hosted in-person in community gardens in all five boroughs in celebration of Earth Week. Join us for workshops about growing food, healthy eating, native pollinators, flower arrangement, planting seeds, screen printing garden swag, volunteer projects, and more. All the activities are free and open to the public!
… The theme of this year’s GrowTogether is “Deeply Rooted: Growing Community Connections.” Community gardeners from across New York City have been gathering at the GrowTogether conference each spring since 1984 to celebrate the start of the garden season with a day of learning, networking, and reconnecting with friends. – Ibid.
– 38th Annual GreenThumb GrowTogether Conference Part 2 Conference Guide
As noted above, all GrowTogether workshops are open to the public. Please register, as some workshops have limited capacity.
This is my first time participating in GrowTogether. I’ll be giving two different workshops on how to use iNaturalist, Friday in Brooklyn, and Saturday on Staten Island.
Using iNaturalist for Community Gardens and Gardeners
Friday, April 22
Time: 11:00 a.m. – 1:00 p.m.
(Rain Date: Saturday, April 23, same time)
Location: Vernon Cases Community Garden, 42 Vernon Avenue, Bedford-Stuyvesant, Brooklyn
Description:
iNaturalist is a community/citizen science platform where anyone can record their observations – photos or audio recordings – of any living thing anywhere in the world. Community gardeners and visitors can use iNaturalist to document and keep records about their gardens, such as flowering and fruiting times; identify and keep track of common weeds; and identify insect visitors, whether pests, predators, or pollinators.
In this workshop, we will use iNaturalist “in the field” to make observations of plants and insects and upload them to iNaturalist, creating a record of the biodiversity in a community garden. If you have access to a smartphone, please download the iNaturalist app in advance and bring it to the workshop!
Meet and Greet New York City’s Native Pollinators
Saturday, April 23
Time: 11:00 a.m. – 1:00 p.m.
(Rain Date: Sunday, April 24, same time)
Location: Hill Street Community Garden, Staten Island
Description:
New York City is home to hundreds of species of pollinating insects. While butterflies and bumblebees are easily-spotted inhabitants of our community gardens, meet a few of New York City’s lesser known pollinators—including wasps, flower flies, and specialist bees— during this workshop with Sarah Ward from National Wildlife Federation and Chris Keussling (aka Flatbush Gardener). During a walk through the garden, participants will learn tips and tricks for observing pollinators and welcoming them into our gardens. Participants will also learn how to use the community science app iNaturalist to identify pollinators and contribute valuable data about pollinators in New York City.

Correspondence, April 2020
I received an unexpected, and much-welcomed, message from a colleague, asking how I was doing. My response ran a little long, so I thought I would reproduce it here. Annotated with links, where applicable.
We are doing well, as well as can be expected. My husband and I have both been (lucky enough to be) working from home. It’s 5 weeks for me this week.
I’ve been writing about the experience on my blog. I started on the Solstice, when I’d already been working from home for weeks. Later posts borrow from my Twitter thread, and past blog posts. I’m sure I’ll be writing more in the days and weeks and months ahead:
https://flatbushgardener.blogspot.com/2020/03/grief-and-gardening-dissetling-spring.html
https://flatbushgardener.blogspot.com/2020/03/drumbeat.html
https://flatbushgardener.blogspot.com/2020/04/grief-and-gardening-feast-of-losses.html
I even got a short piece published in McSweeney’s. And that got picked up to be re-published by YES Magazine. Nothing online yet.
I had multiple engagements planned for this Spring, and into the Summer: speaking on a panel about pollinators in NYC, a neighborhood plant swap, workshops with community gardens. All cancelled. On paper, I’m still going to Eiseman’s leaf-miner course in Vermont in August, but I expect that to be cancelled, as well.
NYC has just started to turn the corner of the immediate crisis the past few days. Recovery – economic, psychological, sociological, political – will be ongoing over generations. There will be an immediate need for trauma and grief support and recovery for emergency, health care, and other front-line workers.
Every night at 7pm, everyone goes outside, into the street, onto their porches, or leaning out their windows, and makes noise for all those working through this, from ER docs to grocery clerks to delivery drivers.
Before everything went whack, I bought a big birding lens. I’ve been out 3 times during this period to Prospect Park. The lens weighs a ton, but it makes all the difference. Adding all my photos as Observations to iNaturalist, of course!
The garden is a salve. I ordered seeds and plants, neither of which I’d been planning to do. I’m giving away plants from my garden to my neighbors to make room for my new acquisitions.
I’ve got a new bee species record for my garden! Just awaiting confirmation from a second identifier.
I’ve vacation coming up, for Earth Day and City Nature Challenge. Planned before all this began. I extended it to make it a solid week. We’re not supposed to be taking public transit for non-essential activities, but I have a car and can get around to most places. Gardens are closed, but public parks are still open, for now. I’m looking forward to some intense observartin’. Both “abroad” and in the garden.

Grief and Gardening: A Feast of Losses
It’s been barely a month since the first handful of COVID-19/SARS-CoV2 cases were reported in New York State. On March 4, there were 6 confirmed cases.
As I write this:
- There are nearly 5,000 dead in New York.
- Nearly 3,500 have died in New York City alone. If NYC was a country, it would be 6th in the world in deaths.
It’s not over. We face the worst in the days ahead. But an end – for New York, at least – is in sight.
It is a strange hybrid collective trauma we are working our way through. So much has changed so quickly. It’s not quite four weeks since I started working from home. My husband started working from home three weeks ago. A week after that, all NYC restaurants and bars were forced to stop admitting guests. On the equinox, I first wrote about living through an epidemic for the second time in my life.
We’ve had the advantage of being able to make (some) preparations for it. Yet we have months of loss and grieving to come.
There is no clear roadmap for how we should react, respond, and recover. Those of us who have survived past epidemics can draw on our experiences, but none of us have ever lived through anything quite like this.
Here’s an excerpt from “The Layers” by Stanley Kunitz (1905-2006), from which I borrowed for the title of this blog post:
When I look behind,
as I am compelled to look
before I can gather strength
to proceed on my journey,
I see the milestones dwindling
toward the horizon
and the slow fires trailing
from the abandoned camp-sites,
over which scavenger angels
wheel on heavy wings.
Oh, I have made myself a tribe
out of my true affections,
and my tribe is scattered!
How shall the heart be reconciled
to its feast of losses?
In a rising wind
the manic dust of my friends,
those who fell along the way,
bitterly stings my face.

City Nature Challenge 2018
The “weedy” remnants of my front lawn, where Viola sororia, common blue violet, has taken charge. Easily overlooked, it seeds itself readily without any help from me (or any other gardener). Yet this species is native to New York City. It’s one of my iNaturalist observations from my garden for this year’s City Nature Challenge.
Today, Sunday, April 29th, is day 3 of the global City Nature Challenge, which continues into tomorrow. Building on the explosive popularity of iNaturalist as a platform for observations, this gamified bioblitz pits cities against each other, to see which can identify more taxa of living species in a 96-hour period.
NYC is currently is 6th place globally, and 4th nationally. There are still plenty of opportunities to join special events organized for New York City, with events in 4 of our 5 boroughs today, and more tomorrow.
I wasn’t able to take part in yesterday’s festivities. This weekend, I have to get my garden ready for this season’s garden tours. Armed with only my phone, I kept an eye out for anything I might see, uncover, or unearth. I was rewarded.
I came up with 16 observations yesterday. In addition to Viola sororia introduced at the top of the post, I observed:
- Moss, one species
- A weedy Prunus (I think)
- Taraxacum officinale, dandelion
- Slug, adult and eggs
- Cepaea nemoralis, grove snail
- Shell of another unknown snail
- An earthworm, genus Lumbricus
- Spiders, 2 species
- Millipedes, maybe 2 species
- Centipede
- Armadillidium vulgare, Common Pillbug
- An unknown fly

Native Plant Acquisitions, Gowanus Canal Conservancy Plant Sale
Today I made my way to my first Gowanus Canal Conservancy Native Plant Sale. Today is Earth Day 2018, and today’s sale was held at their nursery location, the Salt Lot where Second Avenue ends at the Gowanus Canal. They have two more sales this season. The next, on May 19th, conflicts with the NYC Wildflower Week tour of my garden.
A wide range of species are listed are available on their nursery page. Not all of them are still in stock. In compensation, they had other unlisted species available at today’s plant sale.
I used their published list of species to make a shopping list, always a good idea when heading out to plant sales. I cross-checked their list for species that 1) I didn’t already have, and 2) were native to New York City. Since they list the Greenbelt Native Plant Center as a partner, I suspected many of their species would be NYC-local ecotypes. I made a few exceptions for cases where I have the species, but not a NYC-local ecotype, e.g.: Solidago sempervirens, seaside goldenrod.
I had the chance to speak with a few of their staff and volunteers, including Diana Gruberg, their Horticultural Manager for the whole operation. I was pleased when she confirmed that some 90% of their species originated with Greenbelt. They are now successfully propagating many of these species themselves, both vegetatively and from seed.
Today’s acquisitions, listed alphabetically by botanical name:
- Carex albicans, white-tinged sedge
- Carex comosa, bristly sedge
- Euthamia graminifolia, common flat-topped goldenrod
- Juncus greenei, Greene’s rush
- Monarda fistulosa, bee-balm
- Oenothera biennis, common evening primrose
- Quercus bicolor, swamp white oak
- Schizachyrium littorale, dune blue-stem
- Solidago sempervirens, seaside goldenrod, N YC-local ecotype
- Symphyotrichum ericoides. heath aster
- Veronicastrum virginicum, Culver’s root
I confirmed with Diana that the seaside goldenrod was propagated from a Greenbelt collection, so it’s a local ecotype. I don’t know for sure which of the others also are. Odds are good that it’s most, if not all, of them.
