Probably slugs eating the leaves. I have Kassandra and it is huge now. It is in a big pot the size of pots they sell trees in. I plant heucheras and mini roses in them for the patio. I try to plant big pots for the patio with perennials so I do not have to buy annuals every year

I'm pretty sure it's not slugs. The holes aren't typical of slugs, I don't think. I believe it an insect of some kind. And I never have slug damage on anything else. Not even hostas.
The first pic is Hecherella Alabama Sunrise. Not sure about the ID of the second but it is a Heuchera. Any ideas?

Hope you find out what is doing that, never had anything like that happen. There are a lot of lime green ones , possible Lime Rickey or Key Lime Pie.

Yes. I think it is one of those two because I remember buying one or the other years ago. Something with 'Lime' in the name. Or Citronelle maybe?
I hate myself for losing so many IDs over the years.

Look on the back of the leaves and see if you see little green worm look. They are hard to see because they match the leaves so you are going to have to look real close.

If you do not have to many you can pick them off and put them in a soap dish. I get them on my roses.

Go to the bottom of this page. It looks like it also could be japanese beetles.

Thanks for that page. But I'm pretty sure it isn't Japs. I've only seen one so far this year. I'm betting it's worms. I always mean to put down systemic insecticide for my heucheras but I never get around to it. Partly hoping for the best and partly laziness.

@quercusnut
Yes I thought you would know if they were J, Beetles because you cannot miss them. But those green worms are not easy to spot unless you look under the leaves. I have tried everything to grow these in the garden but in pots it is a jewel.

I've been researching beneficial nematodes. I think I'm going to give them a try.

@quercusnut
I have heard those are good. I have never tried them. The only problem I have ever had was slugs on my hostas and I use coffee and epsom salt and do not have any problems.

You can also use Pine needles for mulch , the slugs do not seem to crawl over them.

I did a Google search for diseases of heucheras and the best answer to my inexperienced eye was "heuchera bacterial leaf spot". When I did a Google image search there were several photos of leaf damage that look like what you have in your photos.

Thank you. Something to consider. I adore Heucheras, Heucherellas and Tiarellas. I need to get a handle on this problem.

I saw the name of this thread and it's just what I've been curious about.

After spending way too much money and having so little success I'd given up on trying to grow heucheras (or coral bells, don't know proper name). However a local nursery had a 4th of July sale where it was buy any plant and get others for 4 cents. So I caved and bought the only heucheras that were left. They're in 4" pots at the moment as I'm trying to figure out where to plant them.

So anyway, I took one of these little guys and potted it up. It's still inside but it's also still alive. The others are outside in their little 4" pots and still alive. From reading what y'all have posted it sounds like maybe growing them in pots might be the ticket for keeping them alive.

Since we're having a major heatwave, the ones that are outside are huddled in a very shady spot and I'm trying to keep them well but not overwatered.

Any advice / suggestions / opinions / etc that y'all can share would be appreciated.

BTW — Beneficial Nematodes are great but there's a caveat to that. There's more than one type of Ben Nems and it helps to know what your enemy is before you shell out $$. Of course any type is probably going to benefit the soil. Just saying.
