NYU Garden Shop Plant of the Week

Rose Mallow (Hibiscus moscheutos) on the Bleecker Street side of Coles Sports Center, 181 Mercer Street.
In our region, when we think of Hibiscus, we usually think of tropical plants or the commonly planted small tree or shrub Rose of Sharon. But did you know there's a Hibiscus native to our region, and that it's in flower right now on Bleecker Street at Coles Sports Center? Rose Mallow (Hibiscus moscheutos) grows naturally in marshes and shores from Massachusetts to Wisconsin and south to Texas and Florida. We planted these Rose Mallows about 3 years ago, and they're really coming into their own this year. They reach a height of 4-7 feet and prefer full sun and soil that never really dries out in summer. Don't be worried if you don't see signs of life on this plant in spring, as they typically emerge in early summer. They rarely need to be divided and are long lived, producing large white to pink flowers. In zones colder than Manhattan, it's a good idea to give the plant a think layer of mulch to help it overwinter. We grew our Hibiscus from potted plants, but you can grow them easily from seed. We'll have plenty of seeds to give away in the fall, so let me know if you're interested!
