| Dimensions | 8-10 inches tall, 10 plus inches spread, compact mounding growth form |
| Maintenance | I prefer to gently remove the dead leaves in the spring. Gently is the key word since some Heuchera do not produce stout clumps and pieces are easily broken off. Heuchera may frost heave and a mulch will help prevent this. If they do heaves, gently push the plants back into the ground or digging in to reset the plant. Do this in the spring. Rejuvenation by division may be need as the plants get older and form thick heavy stems at the base of the plant. Depending on the species some will produce a prodigious amount of flower scapes and these should be deadheaded |

| Cultivar Origin | Introduced by Dirk Scheys of Belgium. |
| Author's Notes | I have grown and observed many different Heuchera over the years. I ran a nursery when "Palace Purple" was the most popular. Now there are so many cultivars its mind boggling. In my opinion the best place to grow them is in an area that gets some full sun but the plant isn't baked, like an east exposure. In the full sun they will need some additional moisture. Heuchera Blackout is on it's fourth year in my garden and still going strong (2014). |
