Colorata…not Colorado

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.

Swept Away

Sweeping sedge is in full flower in the garden today. The North American native (Canada south to Florida and west to Texas) Carex bromoides swept us off our feet! This delightful small evergreen sedge forms a 6″ tall x 30″ wide, delicate-textured patch of green hair-like foliage. Although it prefers moist to mucky wet soil, ours has fared beautifully in well ammended compost. Carex bromoides is a favorite meal food for a number of butterfly and skipper caterpillars, wood ducks, grouse, and several songbirds, which in turn eliminates any need for fertilizers. We think you’ll really love Carex bromoides, either as a solitary specimen or in mass.

Shoulda, Coulda, Woulda Bought a Sedge

Back in 2004, I was botanizing in rural Bienville Parish, Louisiana, where I ran across this fascinating narrow-leaf native sedge, a small piece of which returned home for trials. After six years of trialing, we named it Carex retroflexa ‘Bonnie and Clyde’ (alluding to the location where the famous pair met their demise) and added it to our catalog offerings, where it sold a whopping 150 plants over a four year span, ending in 2013. The term “whopping” is used here as a point of sarcastical understatement. Not wanting to discard all of the unsold plants, we planted them around our new patio, where they were interspersed with Heuchera ‘Smoke and Mirrors’ and Penstemon ‘Blackbeard’. Here are a few images from that planting, taken this week. Maybe as the interest in carex increases, we can afford to offer this again.
