Trichostema lanatum (Woolly Blue Curls) - This California native evergreen shrub comes from dry slopes of the south coast ranges. It grows to 3-4 feet tall and sprawls to 4-5 feet with narrow aromatic leaves that are shiny green above and woolly white underneath. From late spring through summer appear the 1 foot long clusters of blue (typically) flowers with long recurved stamens. The bloom period can extend into fall with a little supplemental summer watering (only when soil drains adequately). Plant in full sun in a very well-drained lean soil as it will not tolerate summer moisture in heavy soils. Do not amend or fertilize heavily. Hardy to 10 degrees F without freezing back and has been known to recover from the base at temperatures down to below zero. Gets a little leggy with age and benefits from early pruning. Makes a great cut flower for the vase. Our plants from seed that exhibits some variability in flower color from nearly white to dark violet blue. Another listed common name for this plant is Romero, which comes from the similarities between Rosemary (Romero) and Trichostema lanatum, that were noted during the Portola expedition in 1769. Other names include California Rosemary and American Wild Rosemary.  This information is based on research conducted about this plant in our nursery library and from reliable online sources. We also take into consideration observations of it in our nursery of crops, as well as of plants growing in the nursery's garden and those in other gardens we have visited. We will incorporate comments received from others and welcome getting feedback from anyone who may have additional information, particularly if it includes cultural information that would aid others in growing Trichostema lanatum.
