We’re enjoying the mid-summer show of grass-leaf Barbara’s buttons, Marshallia graminifolia ‘Georgetown’. We grew this from a Patrick McMillan/Zac Hill seed collection near Georgetown, SC. Marshallia graminifolia is a coastal plain endemic, found from NC to Georgia, where it forms a short basal rosette of narrow, linear foliage, that’s topped with 20″ tall flowers stalks, starting for us in mid summer. Each stalk is topped with a frilly, lavender and white button-like flower. In the wild, grass-leaf Barbara buttons grow in full sun, seasonally-flooded, but always moist, sandy soils, along with pitcher plants. This is the first year we’ve had enough to share.
Lovely!
It was stated about occasional flooding? Only from a freshwater river or would the occasional saltwater flooding not kill it?
It doesn’t have any salt tolerance.
