Last year, I planted Jack Frost Brunera in a bed that is shaded by a cedar tree. They looked beautiful. I also had a lime green variety of brunera. In any case, the lime green variety is doing well this spring, but None of the Jack Frost have come back. Can they thrive under a cedar tree? There are also Sycamore and Pecan trees that provide plenty of shade in this particular planting bed. I live in Missouri and the deer are a big problem in my area, so I like brunera because they will not eat them.

Brunnera are shade plants so that's not the problem. How close are the Brunnera to the pecan? Do you know what Juglone is? My other thought is that with all those large trees, there's not a lot of room for other plants: too much competition for nutrients. Variegated plants need more of everything.

Is the soil dry near the cedar tree? Brunnera doesn't like to get too dry - I once tried 'Jack Frost' under a maple tree and while it was shaded it tended to be a dry spot and the Brunnera dwindled away. I have not tried any other Brunnera besides 'Jack Frost' so I don't know if they would have done any better.

There was a nice thread over in the Perennials forum about Brunnera last year. Some haven't had much luck with 'Jack Frost'. I've tried in twice and failed.

Thanks for the info. I might stick with lungwort and ferns 😊

I would try Silver Heart it seems to be a better grower. I have never had a Jack Frost overwinter here, no problem with the Silver Heart.
