Sandhill Wireweed
Also known as Largeflower jointweed, Sandhill wireweed (Polygonaceae) is a deciduous woody plant that produces an abundance of spike-like flowering clusters. The bloom consists of eight prominent stamens surrounded by sepals that range in color from pale pinkish-white to deep rose. The inner sepals are fringed. Leaves are linear and almost needle-like; they are alternately arranged in clusters. Stems are woody and brittle.
Sandhill wireweed is mostly a summer and fall bloomer, with October being its most abundant blooming time, but year-round blooms are not uncommon. It occurs naturally in dunes, scrub and sandhills, and is primarily pollinated by bees. Its seeds are eaten by birds. Sandhill wireweed is endemic to Florida. It occurs nowhere else in the world.
