For the second year running, most of my large lush patch of astilbes has turned crispy. I think I have to accept that thanks to a combination of weather, the neighbours improving their drainage and me planting a crab apple tree, my shady damp border is now a shady dry border where astilbes will no longer thrive. (And a big clump of phlox maculata has vanished without trace.
)
Any ideas what I can replace them with?
