Description Buttercup Winterhazel is named for the profusion of fragrant pastel buttery-yellow flowers it produces in late March before the leaves emerge. A true herald of spring!

  Morphology:
This is a deciduous multi-stemmed shrub that grows in a spreading fashion to 6’ tall and as wide. It bears simple leaves which are arranged in an alternate fashion. The leaf blades are broadly ovate and have a cordate base. At maturity they are 2”-3” long and have bristly serrated edges. The veins of the leaves are deeply sunken making them appear wrinkled. During the summer the leaves are blue-green in color.

Attractive, pastel yellow flowers form in late winter. These are ½” long, in hanging clusters of 3 to 5 flowers.

  Adaptation:
This shrub survives in full to partial sun on moist acidic soils.

  Pests:
None reported.
