Heuchera Primo® 'Black Pearl' Description
When it comes to black foliage plants, Promo Black Pearl coral bells from Proven Winners is one of the best and it's sun loving to boot!
Take your gardening to new heights with the hardy new colorful groundcover foliage plant. You'll find this low growing form very appealing with attractive mound forming habit and dense, stately jet black leaves that spray out flat so you can best appreciate the color. Only 8-10 inches tall and 18" wide so it fits almost anywhere.
Where most coral bells need some shade, these have been trialed in containers in full sun, where it just thrives!
Landscape garden design ideas:
- Use in containers. (They really shine in a white, blue or yellow container!)
- Line a sunny to part shaded pathway
- Tuck into small spaces
- Tuck or edge in front of a medium growing shrub such as buxus
- Mix and match with other colorful heuchera (we like working in blue - such as hosta Blue Mouse Ears)
- Yellow - such as lysimachia aurea, acorus, carex Bowles Golden, Thuja Forever Goldy
- Blue - carex Blue Zinger, festuca, campanula Rapido Blue
- Greens - such as hardy ferns, or buxus
No perennial garden is complete without a few heucheras dotted around the landscape. They are widely adaptable to various soil types and temperature extreme and keep their good looks from spring-fall. Heuchera prefer a rich, humus, moisture retentive soil. Take care not to bury the crown as it should sit at the soil line. They are not heavy feeders and have low fertilizer requirements.

Soil: Coral bells like a neutral to slightly acid soil pH, somewhere between 6.0 and 7.0. Good drainage is a must, especially in shaded areas. They do well in soil where some organic matter has been added.
Light: As a general rule, heucheras do well in shade, but for the highly colored varieties, some morning sun will bring out more intense coloring. The color can wash out in full sun, and too much heat and light can cause the leaves to scorch.
Water: Average -- better too dry than too wet when established. Keep the soil evenly moist, but not consistently wet to prevent root rot. To reduce the risk of foliar disease, heuchera require watering during the early morning so any excess moisture can evaporate before evening. Drip irrigation effectively delivers moisture directly to the soil, further reducing the plant's vulnerability to disease.
Spacing: 1.5 ft
Fertilizing: Use good quality compost, or well aged livestock manure, or a combination of the two. Apply a few pounds for each plant, each year or two. On poor soils, top dress every year, or every other year on moderate quality soils. Spreading a 2-inch layer of mulch over the soil surrounding heuchera helps insulate the soil during winter, and improve moisture retention. About 3 inches of space between the plant's crown and the mulch allows air circulation, which prevents rotting and disease. Replenishing the mulch throughout the year ensures proper winter protection, and hinders the establishment of competitive weeds. Heuchera does not require fertilization during the fall or winter months.
Winterizing: Winter mulching will prevent the freezing and thawing that can heave plants roots.
Maintenance & pruning: Cut back the entire flower stalk after flowering to put the plants energy into growing more leaves. Divide coral bells every 3-5 years to keep them from dying out in the center.
ReviewsWrite a reviewUSDA 9 does not equate to heat zone 9Ann Fraley | Jul 22, 2020The caption says it colors up best in full sun. I live in the Houston area, zone 9, and the leaves on this one do fry in the afternoon sun. It's only very late afternoon, well past the hottest hours but it just doesn't like it. Also, you can probably tell but they should have been named "Purple Pearl". Just sayin'. Still, happy with them, but we have to be reminded sometimes, that "full sun" doesn't mean "full Houston sun".
Very FrustratedSharon Marini | Jun 27, 2020The plants came nicely packaged and a good size very healthy. The main reason I purchased these Heucheraas was because they were advertised as deer resistant in the product description on your website. I planted 8 of them in the afternoon and the next morning the deer had eaten them down! I am extremely disappointed that I trusted the recommendations from Great Gardens web site only to find their information on deer resistance to be untrue. I spent a lot of money and time digging and planting these 8 plants.
