Lobelia laxiflora – Branches with narrow green leaves and red stems arise from underground rhizomes that spread outward, allowing a single plant to form a dense groundcover to 18 inches tall by many feet wide.

In Santa Barbara this plant is nearly always in bloom, with a peak bloom period in summer. Plant in full sun to light shade. Can tolerate little water but also grows well in moist soils where it can prove to be somewhat invasive. It is hardy to about 15 degrees F. The genus is named for Mathias de L’Obel (latinized to Matthaeus Lobelius) (1538 –1616), a Belgian botanist and physician to the royal families of the Netherlands. Native to Arizona, Mexico and Central America.
