Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Plants for a bioswale in New York City
Answered by: Nan Hampton

QUESTION:

I am interested in learning about the best vegetation for planting in a bioswale in New York City. Can you help? Thanks!

ANSWER:

Bioswales, or rain gardens, require plants that must be able to tolerate growing in standing water, but also need to be able to thrive when the water dries up.  Below are some that should work in your New York City bioswale.  Since I don't know the other aspects of your site, such as how much sunlight it gets, you should check the GROWING CONDITIONS on each of the species pages to see if they are compatible with those of your site. 

Grasses/Grass-like

Andropogon glomeratus (bushy bluestem)

Carex stipata (owlfruit sedge)

Calamagrostis canadensis (bluejoint)

Perennials

Asclepias incarnata (swamp milkweed)

Chelone glabra (white turtlehead)

Hibiscus moscheutos (crimsoneyed rosemallow)

Monarda didyma (scarlet beebalm)

Ferns

Athyrium filix-femina (common ladyfern)

Osmunda cinnamomea (cinnamon fern)

Shrubs

Cephalanthus occidentalis (common buttonbush)

Physocarpus opulifolius (common ninebark)

Clethra alnifolia (coastal sweetpepperbush)

Here are photos from our Image Gallery:
