Another of our favorite early summer plants is the amazing southeast US native Dichromena colorata (aka: Rhynchospora colorata). Known by the common name, white-top star grass/sedge, this tough-as-nails groundcover can be found inhabiting moist ditches from NC to Texas. The floral show last for 1-2 months, depending on weather. Here, we have it growing in regular garden soil (sandy loam) amended with compost, and irrigated regularly. White-top sedge does spread, but not aggressively. Regardless, we’d recommend keeping away from nearby wimpy growers, which would be quickly consumed. Hardiness is Zone 7a and warmer.
