Can someone who has these varieties in their garden tell me how much sun they can take? I'm seeing a lot of conflicting info. The place I want to put them gets a lot of morning to early afternoon sun, and is in a dry spot. I had read that the darker colored or all green varieties can withstand more sun, but I saw that one of the darker Indian Summer varieties I put there had scorched leaves pretty quickly. I hate to waste the time and energy putting any of the 3 I mentioned there, and then have to move them somewhere else later. Thanks for your input!!!

I have a number of heuchera in full sun in zone 6a. But none you listed. Timeless Night is doing very well. I tried Fire Alarm a few times under different conditions and it never overwintered. For a red look see if you run across Monster Mahogany which has done great for me. Others I have in full sun that have done well are Brownies Pinot Noir , Pinot Gris , Caramel, Midnight Rose , Northern Exposure Silver, Encore, Mocha. Frosted Violet and Bronze Wave. All burn a bit at first if I get them from a place that grows them in shady areas , if they were already in sun they do fine.
