Willowy Monardella
Monardella viminea
  
About Willowy Monardella (Monardella viminea) Nurseries Show All Photos Willowy Monardella (Monardella viminea) is an extremely rare native perennial herb in the Lamiaceae (Mint) family that grows almost exclusively in San Diego County and northern Baja. It is listed as Endangered at the federal level and is included in CNPS list 1B.1. Within San Diego it is found in small isolated occurrences within three watersheds, no more than 30 miles from the coast. Only eight naturally occurring locations are known to exist. This species was formerly classified as a subspecies of Monardella linoides, and many sources still list it that way.

Despite its rarity and protected status, this plant has been propagated and is sometimes available at nurseries. It has a delightful fragrance. The pink to lavender flowers are quite attractive, and it does well in containers. Although it can be tricky to provide the right soil and water conditions, it is recommended for coastal gardens in the southern part of the state.

Site Type
In the wild this plant is found on marine terraces, mesas, benches, and stabilized sandbars along ephemeral drainages in coastal sage scrub or riparian scrub habitat. These semi-open washes and drainage areas typically contain little to no canopy cover and are maintained by large intermittent water flows that erode and deposit alluvial material, developing benches and sandbars.
