Description |
||
White prairie clover (var. candida) is a 1′ to 3′ tall, erect, perennial forb that rises on one to several stems from a taproot that can extend up to 5′ into the ground. The stems light green, slender, erect or spreading, straight, unbranched or sparsely branched toward the top, hairless, and ridged. The leaves are alternate, ¾″ to 2½″ long, on short stalks. They are divided into 5 to 9 leaflets, usually 7, always an odd number. The leaflets are pale green, untoothed, and hairless. They are ⅜″ to 1⅛″ long, less than ¼″ wide, and inversely lance-shaped with the attachment at the narrow end. The end leaflet is longer than the lateral leaflets. The tips are rounded with a short, sharp, abrupt point. There are minute glandular dots on the lower surface. The inflorescence is dense, cylinder-shaped spikes of flowers at the end of each stem. The spike is more than twice as long as it is wide, ⅔″ to 2⅓″ long, and about ⅜″ wide. The flowers at the base of the spike bloom first, forming a white ring. As the season progresses the ring moves up the spike or expands to encompass the entire spike. The flowers are about ¼″ long and about ¼″ wide, numerous, white, and fragrant. There have 5 white, long-clawed petals. The petals do not form the typical banner, wings and keel of most plants in the Pea family. Instead, there is a banner petal and four petals fused with the 5 stamen bases into a floral tube. The fruit is an oval pod about ⅛″ long with 1 seed. |
