I am a heuchera novice, I have four from nursury, yet my mum who almost lives with us put small cutting all over from her own garden. Since we have a large garden, this is the score:
1) cuttings are in heavy clay and exposed to strong winds have done really badly, ie they didn't grow an inch since last summer, however they are not dead yet and may try to get up and go this season.
2) Two reasonable size heuchera's from nursury are in a dry, sunny and exposed postion, yet soil has slightly better drainage than above clay have survived winter and escaped various animals attacking other plants such as lupins and lambs ears around them, look fine however they don't seem to have added more leaves on or made any progress.
3) Two heucheras from Coblands, one dark and one chocolate in our front garden which are near and part forest condtions, ie moist dark, under trees so soil is rich with leaves and mould, mostly shady throughout the day, seem to be glossy, added leaves on and very happy inspite of previous nibbles
I think for me the answer is visible.
Enjoy and good luck.
