Tiarella wherryi is a related species with pink flowers and a clump-forming habit, which is native from Virginia and Tennessee to Georgia, Alabama, and Mississippi. Foamflower is a low, evergreen woodland plant that has dainty maple-like basal leaves and white flower spikes. It should be mulched well and watered in times of drought. Plants can be increased by lifting mature clumps in fall or early spring before flowering and gently separating the crowns. A mature plant should yield from four to eight crowns.
Flowers mature from the bottom of the spike to the top.
Begin looking for ripe seed approximately five to seven days after the uppermost flowers have faded. When the minute, shiny black seeds are mature, cut the stalk below the bottom seed capsule and carefully deposit in a paper bag. Seeds are easily lost, so move slowly and hold the seed pods over the bag before tilting them into the bag. The seeds may then be refrigerated until a later time for sowing. Since seeds are so small, direct sowing in the garden is not recommended.
