Flowers are in a tightly packed cluster at the top of the plant that spreads out as the plant matures. Smaller clusters develop from the leaf axils near the top of the plant. Individual flowers are about ¼ inch across with 15 to 30 pale blue to whitish petals and numerous stamens with curly blue tips. Leaves become progressively smaller as they ascend the stem. Those near the base of the plant are up to 12 inches long and 6 inches wide, deeply divided into several wide coarsely toothed lobes with pointed tips. They are roughly triangular or arrow-head shaped in outline, with “winged” leaf stems.
