HI, Mary, You are not alone with temperamental Heuchera. A couple of things could be causing poor growth: 1) Even though sold as a shade-loving plants, Heuchera do best in partial shade. 2) Heuchera roots tend to 'lift' out of the soil over time. They should be lifted and replanted or mulched every year. 3) Heuchera do best in neutral soil and they don't like clay - loam or sand is best. 4) Climate - not sure where you live but too hot and humid could cause poor growth. Too dry or too wet could as well. Any of the above sound like possibilities? Kathy C
I have four v.green plants. Two in shade (I bought them to cover weeds IN shade and grow into each other). The other two in sun (where I know they shouldn't grow ). Both have grown equally as badly. They have been there three years and are still only 8" across at best. Why? They are under a v.firtile/tall holly. The others near it. Nearby plants do well except Roses. The soil is well draining alkaline.
