Starrush whitetop (Rhynchospora colorata)
Click on terms for botanical definitions.
Starrush whitetop is a unique and long-lived perennial sedge. It is known (and named) for its striking bracts that are often mistaken for a daisy-like flower. The bracts are white with green tips, giving the appearance of having been spray-painted. The inflorescence is actually a dense cluster of small spikes, each bearing many tiny flowers. Leaf blades arise from the base of the plant and are long and tapering.
Like most sedges, starrush whitetop stems are triangular. But unlike most sedges and other grass-like species, which are wind-pollinated, starrush whitetop is pollinated by insects that are attracted to the showy bracts.
Starrush whitetop occurs naturally in wet flatwoods, wet prairies, swales and roadside ditches.
The genus name comes from the Greek rhynchos (beak) and spora (seed) and refers to the plant’s beaked fruit or achene.
