Kosteletzkya virginica is a shrubby perennial that will grow up to a height of 5 feet. The flowers are similar to those of Hibiscus which is another member of the Mallow family. They are white or pink, only about 2" in diameter but plentiful. This mallow has attractive, gray-green, hairy leaves. These may appear as slightly serrated, elongated triangles, or lobed and maple-like.


This emergent species is adapted to salt marshes and brackish environments where it can withstand regular inundation. It is salt tolerant but can be grown successfully in freshwater gardens, around ponds, and even in a conventional garden setting, provided the soil remains consistently moist. It is not particular about soil, but requires full sun. Virginia saltmarsh mallow will bloom profusely for up to 3 months, as early as June and as late as October, depending on geographic location. A heat loving plant: zones 6-10


Propagate from seed. It may also be propagated by tip cuttings taken in early summer before plants start blooming.

Additional Notes

Virginia saltmarsh mallow is attractive to nectar loving insects and birds. Flowers close at night. Individual plants have a short life cycle of about 5 years, so it is recommended to allow them to self seed.
