Snow Squarestem

Snow Squarestem (Melanthera nivea) is a Florida native we’ve recently added to our Woodland Wildflower Garden bed. Snow Squarestem is found throughout Florida, as well as the Southeastern U.S., Mexico, and the West Indies. It likes well-drained, sandy soils and lots of sun, and is drought-tolerant once established. It’s a somewhat sprawling plant, growing to 4 feet high and wide under ideal conditions, and is probably more appropriate in a native wildlife garden than a more formal setting.

The name Melanthera nivea literally means snow-white (nivea) with black anthers (melanthera). The anthers of a flower are found at the end of the stamen, and generally contain the plant’s pollen. Looking at a close-up of the bloom, it’s easy to see why Snow Squarestem was given this botanical name, along with another of its common names: Salt-and-Pepper.

Snow Squarestem has high nectar value, and draws butterflies as well as bees and other pollinators. It may be difficult to find even at native plant nurseries, but is easy to propagate if you have a source. It’s known to grow from both seeds and stem cuttings, so if you find it in a neighbor’s garden, ask for a piece to get your own plants started.
