It would depend on how many heucheras you really like and which ones they are. I prefer the variety of plants approach but ymmv. Where in the world you are would dictate what plants you could grow with them.

I am in Michigan in zone 5B. I have always liked Heucheras and have had them scattered in my flower beds for years. I am working on a new spot that I can see from the house and would really like to transplant my Heucheras into that spot, so there is a intense showing of them. The area is 5' by 12', I'm guessing, on a slight incline and on the edge of some trees. I have about a dozen different colors (purple, orange, green and marbled) and didn't know if someone had a suggestion of placement, color wise, so that I don't have to think too hard about it. I guess it'll be a shot in the dark as long as they compliment each other. I am going to have a solid green hosta behind the Heucheras and the other half of the planting area is going to have a bleeding heart (that my daughter gave to me about 16 years ago) with raspberry splash lungwort, jack frost brunnera and a lady's mantle. Love to see some pictures of similar areas you have done. Thanks for any ideas you might have.
