Purple Palace is fantastic. Very hardy.

Bunnies opt for my hostas before my heucheras. But if you need a little extra insurance, you can use Liquid Fence to keep them at bay.

I have all the following that perform well for me....

Amethyst Mist, Stormy Seas, and Plum Pudding. I just added Midnight Rose and Frosted Violet last season. So the jury is still out on those two, but so far they seem to be doing well. I am replacing my Palace Purple with newer cultivars that I find perform better.

Not sure those fit what you are looking for, but that's my two cents. As far as bunny damage, I have never had that problem even though I usually do find a bunny or two in the yard. They seem to be more interested in the clover in the law*n. I would think if a bunny will eat one heuchera, they will eat any heuchera, no?

I have Cherries Jubilee and Purple Petticoats. Both have performed very well. Although Purple Petticoats is very pretty, the bloom is the dingy white common to many Heucheras. Cherries Jubilee seems to be hard to find and I don't understand why. The bright cherry pink bloom is outstanding and begins early and stays late well above the deep purple/green foliage. Here it is.

Hands down, without a doubt, for me it is Plum Pudding!

I second the nomination for plum pudding...great color

The most vigorous and reliable of the @six kinds I grow has been Amethyst Mist. It has gone thru all kinds of winters. I have eight of this cultivar in an exposed, unfriendly position and they do great.

All heucheras benefit from being dug up every year or so and planted deeper. It's that climbing out of the ground thing that does so many of them in.

Another vote for Amethyst Myst as the most vigorous and I grow a large number of heuchera. Plum Pudding is a good one too. Palace Purple sometimes has a good purple color that will last.

mao

Flora, the plant in your picture is not 'Purple Petticoats' as it has creamy-white-green flowers.

Thanks everyone. I'll look for Amethyst Mist and Plum Pudding when I go to the nursery today.

gazania~Cherries Jubilee looks like a real stunner, thanks for sharing with us! The blooms on heucheras are often overlooked.

I ended up getting Plum Pudding. They didn't have Cherries Jubilee or I would have gotten that. Plum Pudding looks really nice though and the plants are big already.

Late to the party but Amethyst Mist is the best performer for me. It does not diminish like a lot of the others. I love, love, love the color of Frosted Violet but alas, it too is the incredible shrinking heuchera. I also have Plum Pudding but it's getting smaller too. Good conditions are critical. Palace Purple is meh, blah, there are so many better ones out there now.

Stormy Seas is a vigorous one that has lasted a while too.
