Heuchera Primo Black Pearl
Heuchera Primo Black Pearl
Coral Bells

Heuchera ‘Black Pearl’ forms an incredibly dense mound of shiny, jet black leaves with scalloped, ruffled edges. Each large leaf has rosy purple undersides, revealed with the intense ruffling of the leaves. Oldest leaves have a slight silver overlay. To top it off—‘Black Pearl’ keeps its intense black color even in full sun, instead of bleaching to brown. White flowers with pink calyxes appear in midsummer. This plant is a Heuchera villosa hybrid. The villosa species is a large, late blooming type that exhibits an increased tolerance of high heat and humidity over other species. Most produce cream flowers in midsummer, though they are grown more for their fantastic foliage. H. villosa is native to the southeastern United States.

Growing and Maintenance Tips

Heucheras are easy care perennials. They like rich, well drained soil with a neutral pH. They dislike wet soils especially in the winter. Amend the soil with organic matter to enrich it but do not add peat moss which they dislike. Situate Heucheras where they will receive morning sun and shade over the hottest part of the day. 'Black Pearl' will thrive in full sun as long as there is constant moisture. Heucheras are evergreen so do not cut them back in the fall. Clean up tattered foliage in the spring. They will benefit from a winter mulch to prevent them from heaving out of the ground due to the winter freeze thaw cycle. Heucheras are somewhat salt tolerant so they can be used along pathways where salt might accumulate.
