Introduction:Lespedeza capitata is a perennial species of bush clover that typically grows to 2-4' (less frequently to 5') tall on stiff upright stems. It is native to Missouri where it is commonly found in upland woods, thickets and prairies, on glades and along streams, railroads and roadsides (Steyermark). Tiny creamy white, pea-like flowers with a magenta spot at the base of the standard bloom in dense, rounded heads (axillary clusters) in mid to late summer. Trifoliate, alternate, almost stalkless leaves have three narrow-oblong leaflets. Leaflets may be green with little hair to gray-green and hairy depending upon the particular variety or form.
