This season was the first time I saw this plant, I love it. It is in a rather flat pot with purple petunias and has been great all summer and still is. In partial shade on a deck. I am in Zone 5a.

A small shrub from Mexico.

Has toothed or entire, mid-green leaves, the whole plant is softly hairy and slightly sticky. Bears tubular reddish coral flowers with a green/yellow tip and two tiny blue-violet petals.

Flowers between mid April to mid September.

Needs a well drained soil in sun or light shade, it very much appreciates shade from the sun during the hottest part of the day. This plant won't take frost so, if you live in a frost prone area, you either need to bring it in over winter, propagate each season or treat it as an annual.


This plant has been said to grow in the following regions:

Los Angeles, California
