Flowers of solanum parishii
are typical of this genus; a five-lobed corolla, about one inch in diameter, which when fully open bends back below the plane, exposing a yellow center of fused, elongated, yellow anthers, supported by short green filaments. A white style extends through the middle, terminating in a greenish stigma. The corolla is usually purple but can also be white. The bases of the corolla lobes are light green or whitish, with a darker green patch in the middle. The corolla tube is supported by a five-lobed, bell-shaped calyx, which is green to purple in color, similar to the short stalks below.
Plants are shrub-like, growing up to 3 feet tall, and freely-branching. Leaves and stems usually have a sparse covering of very short hairs. Leaf edges are entire but can be somewhat wavy. Stems are ridged.
