Summary

Trichostema lanatum, commonly known as Woolly Bluecurls, is an evergreen subshrub or shrub native to the chaparral and coastal sage scrub of California and the northern part of Baja California in Mexico. It typically grows to a height of 1.5 meters (5 feet) and is characterized by its many-branched form and narrow, pointed green leaves that emit a pleasant fragrance when crushed. The distinctive flowers of Woolly Bluecurls are a striking blue color, with smooth petals and dense clusters that bloom from March to June. The stems and calyces are covered in woolly hairs, which can appear blue, pink, or white, adding to the plant’s ornamental appeal.

Woolly Bluecurls is valued for its vibrant blue flowers and aromatic foliage, making it a popular choice for native plant gardens, xeriscaping, and as a border plant in dry climates. Its low water requirements and preference for well-draining soils make it suitable for drought-tolerant landscapes. While it thrives in full sun, it can also tolerate part shade. Gardeners should note that Woolly Bluecurls can be challenging to establish and may not transplant well, but once settled, it requires minimal maintenance. It is not known for significant disease problems, but overwatering can lead to root rot.CC BY-SA 4.0
