18-24" x 18" wide, (cutting propagated). 'Buena Vista' is a very special cultivar. It blooms twice per season (late spring and again in fall, in areas with a moderately long growing season), has superb fragrance and eye-catching, strongly bi-colored flowering spikes with a lax, informal habit. Bred in Oregon, 'Buena Vista's' attractive elongated flower spikes have very dark blue calyxes and lighter blue corollas (flowers) that are very different from more compactly flowered English lavenders like 'Hidcote Superior'. This is a distinctive and highly desirable cultivar not often available to the gardening public. *Not recommended for fall planting in Zones 5 & 6.* Zones 5-10.
