x Heucherella –
This genus comprises crosses between Heuchera and Tiarella, which make evergreen, mat or clump forming, occasionally stoloniferous perennials. They have heart shaped or broadly rounded, lobed, distinct veined, sometime hairy leaves, shaded brown when young and turning reddish brown in autumn. Short loose panicles of dainty tubular-bell shaped, pink or white flowers, to 1/4″ long, are borne over a long period from late spring to autumn. They are excellent as a groundcover or edging in a herbaceous, mixed, or shrub border, or for a woodland garden.
Easy to grow in light, fertile, moist but well drained, neutral to slightly acidic soil, in sun or partial shade is best, but full shade is tolerated. Divide in autumn or spring.
