This rare and elegant perennial has glossy green heart-shaped leaves on maroon petioles and bears small, starry white flowers on wiry stems well above the foliage in spring. Foliage aquires bronze tints in cooler temperates. Height 18 inches;spread 24 inches. An excellent ground cover for shady sites; associates well with ferns, epimediums, hostas and hellebores. B. calthifolia has more smaller and more numerous 'teeth' on its leaf margins than does B. deltophylla.
For maximum freshness, please keep seed refrigerated in its original packaging until it is time to plant. Sow seed in containers in a cold frame as soon as available. Seed germinates easily within one year with and without stratification, although stratification does improve the rate of success. Grow in moist but well-drained soil in part- to full shade.
