Flowers of solanum xanti
are borne as a small terminal cluster, each head joined to the stem by a short, purple pedicel, which, like the greenish stems and the thick green leaves, have a dense covering of short white hairs. The flower head is formed of five purple or bluish lobes, not divided, opening out to a near-planar pentagon. Each lobe has two green spots near the base, surrounded by a thin band of white. At the center are five, thick yellow anthers and a slightly longer style. Under favorable conditions the plant forms substantial mounds, several feet high and wide. This species is similar to solanum umbelliferum
, but is hairier and has larger leaves.
