Ground covers, Perennials, Flowers
Vast and varied group (about 300 species) encompassing trailers, creeping or tufted miniature perennials, and erect kinds 1–6 ft. high or taller. Usually, flower stalks rise above basal leaf rosettes; basal leaves often differ from stem leaves. The perennial species tend to spread indefinitely from the root; width depends mainly on vigor of their rootstocks and the time they have been in one spot. Flowers are generally bell shaped, though some are star shaped, cupped, or round and flat. Bloom comes at some time from spring to fall, depending on species. Most species are grown fairly easily from seeds sown in spring or early summer.
Spreading, mounding, leafy clump to 8 in. high. Branching, semi-upright flower stems to 1 ft. or more. Elongated heart shape, irregularly toothed, slightly hairy leaves are 1–3 1/2 in. long and 3/4–3 in. wide. Star-shaped, 1/2–1-in.-wide blooms in blue-lilac, lavender, or grayish white. Spring to early summer blooming.
Very vigorous. Good for shaded border near pools or in partially shaded rock gardens with fuchsias and begonias. Good groundcover for small area. Needs little water.
