Trichostema ovatum is an uncommon species of flowering plant in the mint family known by the common name San Joaquin bluecurls.[1]

Distribution

[edit]

It is endemic to the San Joaquin Valley of California, where it occurs in grassland habitat, as well as disturbed and alkali soils, such as chenopod scrub.

Description

[edit]

Trichostema ovatum is an annual herb approaching 80 centimeters in maximum height, its aromatic herbage coated in woolly glandular and nonglandular hairs. The pointed oval leaves are 1 or 2 centimeters long. The inflorescence is a series of clusters of flowers located at each leaf pair. Each flower has a hairy calyx of pointed sepals and a tubular, lipped purple corolla. The four stamens are long and curved, measuring up to 1.6 centimeters long.

The plant blooms in May through October, with peak flowering in the hot summer.[2] Adequate rainfall is necessary for germination.[2]
