Each system will include 12 experimental plots, 85 square feet each, with soil depths ranging from 4 to 6 inches.Here are the species they've specified from each community:
Each plot will be planted with a species mix from two native plant communities, the Hempstead Plains (Long Island) and Rocky Summit Grasslands (e.g. Bear Mountain) of the New York City region. These models were chosen because they are meadows, have plants that can tolerate the desiccated soils and high winds typical of roof conditions, and provide prime foraging for native insects and birds.

Hempstead Plains:
- Schizachyrium scoparium, Little bluestem (Grass)
- Panicum virgatum, Switchgrass
- Sorghastrum nutans, Indian grass
- Baptisia tinctoria, Yellow wild indigo
- Solidago nemoralis, Gray goldenrod
- Asclepias tuberosa, Butterfly-weed
- Eupatorium hyssopifolium, Hyssop-leaved boneset
- Rubus flagellaris, North Dewberry
- Carex pensylvanica, Pennsylavania sedge
- Danthonia spicata, Poverty-oat grass
- Deschampsia flexuosa, Common Hairgras
- Lespedeza capitata, Bush-clover
- Lysimachia quadrifolia, Whorled loosestrife
- Cunila origanoides, Stone-mint, Dittany
- Solidago odora, Licorice-goldenrod
- Vaccinium angustifolium, Low-bush blueberry
I would expect that these plants have been propagated at the Greenbelt Native Plant Center. I'm trying to confirm that.

Hello Flatbush Gardener. Found you through the nature blog network.
ReplyDeleteQuery: some of the species you mention for the green roofs develop very deep root systems. Will the roots grow horizontally? I thought that's why sedums are so popular.
Thanks,

Good question!
ReplyDeleteAt least part of this is a trial to see how well these species perform on green roofs. I'm hoping that some folks involved in the project can weigh in.
