There are quite a few nice heuchera around that match what you're looking for. Afternoon shade will be great for growing most of the lime green ones, as they burn in afternoon sun. I'll post some that I think you might be interested in. Also, if you search my threads you will be able to see the ones you're interested in at different times if the year. Heuchera tend to change color quite a bit. They're at their brightest in spring and/or fall. Some of mine have already begun to fade a bit, but you'll get the idea.

This first one is 'Zipper'. It's even brighter orange at the start of spring and turns bright orangey-red in fall.

Heucherella 'Stoplight'

'Rio' is super bright and has large leaves.

'Root Beer' is red now and in the fall. In the summer, it's more the color of root beer...hence the name.

Heucherella 'Blue Ridge' is interesting. It's a different green than you'll see in most heuchs.

'Southern Comfort' gets pretty large and has great color.

If you're looking for something small, 'Sweet Tart' is a mini.

Heucherella 'Brass Lantern' offers all sorts of cool color changes.

'Delta Dawn' is bright green in the summer. The leaf center is red in the spring and fall.

'Mahogany' has shiny leaves and rich color.

'Pear Crisp' is super bright yellowish-green. I like the serrated leaves on this one.

Heucherella 'Sweet area' is a forum favorite. It's a large plant.

'Lime Marmalade' is a good grower.

'Dolce Peach Melba' is a pretty, peachy-orange.

'Circus' is green with bright red veins.

Thank you Flower- frenzy all those are just gorgeous. Now I want them all but think I have room for maybe 3-5 more, or if I extend the garden 15-20 more :) I appreciate your help

dazlr, I suggest looking up what will grow in your zone. Although Herculeras are sold as hardy zone 4- 9 it really is not true. I remember running out all excited at all the pretty leaves and after winter or a rainy summer I was looking at dead coral bells I have learned to read up on what has been developed and who developed them. Which Coral Bells will survive my environment.

I have had trouble growing anything that was developed by TN. Some developers are rushing them to the market and they were not tested in enough region/zone gardens for viability.

Wonderful if you do not have a harsh winter environment but at the price of these plants it is not the most pleasant experience when spring arrives and you are looking a dead coral bells.

Just be careful what you fall in love with and check the boards of what people have had survive in their gardens in your zone.
