Trichostema lanatum

Trichostema lanatum

Trichostema lanatum (woolly blue curls) grows to three to five feet high and four to eight feet wide.  The dark green leaves are pungent when bruised.  The purple flowers are fuzzy and appear in spring.  The plant will continue to bloom during summer and autumn if it is deadheaded.  Trichostema takes full sun and needs no supplemental water once established.  It does, however, require extremely good drainage.
