These perennials just bloom their sweet little heads off! Upright stems with vibrant green foliage 24-30” tall in a 2’ wide clump are topped with pucker up red violet tubular flowe rs (hummers must see these from a million miles away) from early summer right up until frost if deadheaded once in awhile. Full sun, soil with decent drainage, occasional water. Show more
