Detailed Information

Flower:

Flowers are in spike-like racemes that branch off the main stem near the top of the plant. Individual flowers are about ¼ inch across with 5 yellow petals and orange-tipped stamens. The bract under the flower has a ring of tiny bristles. The spikes tend to elongate as the plant matures, the flowers becoming more widely spaced apart. Flowers bloom from the bottom of the spike up.

Leaves and stem:

Leaves are compound in groups of 5 to 9 large leaflets, with small leaflets in between the larger ones. Leaflets are up to 3½ inches long and 1½ inches wide, becoming smaller towards the base of the leaf stem. Leaflets are coarsely toothed, pointed at the tip, and are hairy along the veins on the underside. The main stem is covered in long spreading hairs, becoming sparsely hairy at the top of the plant.

Fruit:

Fruit is a dry seed, the top covered with hooked bristles
