General Culture:
Best grown in a light, moderately dry, well-drained sandy loam. Best in cool summer climates. May struggle in the heat and humidity of a typical St. Louis summer. Plants are generally best left undisturbed once established.
Noteworthy Characteristics:
'Blue Diamond' is a dwarf sea lavender cultivar which typically grows to only 10" tall. Features a rounded, cloud-like mass of tiny blue flowers on long, wiry, multi-branched, nearly leafless stems which rise from a sprawling basal rosette of leathery, oblong-elliptic leaves. Blooms in summer. Valued for dried flower arrangements.
Problems:
Crown rot and root rot are occasional problems. Well-drained soils and good air circulation will minimize the onset potential for these diseases.
Uses:
Rock gardens, border fronts or containers.
