Kirengeshoma (yellow wax bells) is one of those perennials that I couldn't live without in our garden. I brought a piece from Green Dome Garden in Brooklyn, where we volunteered, shortly after we moved. Green Dome has a nice group of three in the shade of a huge oak tree. I have room for one due to its large size. I think this one is kirengeshoma palmata, but I've never been sure. It's originally from Japan and Korea, but grows happily on the north side of our garage, in a shady, moist spot. I value it for its late bloom time and shrublike stature. My kids love the thick, foamy feeling of the flowers.
I just wished they lasted longer. As soon as I notice that they are fully open, they start to drop.
