My plant has very poor form. The leaves are large and just lay there.

Nice colour, but weakest of the Coral Bells I planted. Emergence was slow in the spring and lags behind two others I planted ("Dolce Licorice" and "Dolce Key Lime Pie"). By the second year, it was dead.

I find this to be a very hardy Heuchera, although a slow grower. Mine is planted in a bed that receives a fair amount of late afternoon sun.

I planted two of these in a very shady spot beneath my big Japanese Maple back in March and they have thrived. One is now beginning to bloom. Perhaps it's just due to aggressive countermeasures, but they haven't yet been bothered by the snails and slugs that decimated the hostas that were previously in the same spot. These are very pretty plants and easy to grow in my area.

This is the weakest of my coral bells. It seems to struggle for survival each year and doesn't grow as large as the others. I think I would say it is marginally hardy in my zone.

Planted one this spring and have already divided it into 3 quite large plants.Very vigorous grower.Also planted Amber Waves in the same spot(east wall) and while colouration is very similar Marmalade has slightly more crinkly leaves and is a MUCH faster grower.
