Yellow wax bells (Kirengeshoma palmata) is an exception to the rule that most shade-loving perennials bloom in the spring. Growing to a stately six feet tall and producing numerous waxy, bright-yellow, bell-shaped blooms, it really does live up to its name.
These blooms open from August into September, and it is a lovely plant for a tree-shaded garden area.
Related to the hydrangea, it is native of Japan and Korea but makes itself perfectly at home here in our Shade Border. There is a large clump near to the arbor—close enough to admire while you are seated on one of the benches.
