This is a native in the Pacific Northwest, it has done well in a predominantly dry bed under a native Garry oak and beside other PNW natives, occasional water the first summer. Mine blooms May-August

Another member of the Dasanthera Section, this one is relatively easy to accomodate. It can take a fair amount of drought but performs better with adequate moisture. Plants form an evergreen subshrub to nearly 2 feet. Winter foliage can turn purplish. Typically the flowers are purple to blue-purple but I grow a dwarfer, reddish-pink flowered version called 'Roseus'. The blooms are relatively large.
