This perennial will grow 1.5'-2.5' tall and 1'-2' wide. It has medium-size green leaves with lavender-blue flowers that appear in summer through fall. Blooms resemble pin cushions on top of thin, wiry stalks, attracting butterflies. This plant prefers full sun, well draining soil and regular moisture, more during hot summer months. Great for borders and rock gardens. Foliage is narrow, gray green.
