Spike Winterhazel. This is a larger version of the Winterhazels with heart-shaped serrated leaves of 4" or more across. Smaller in a sunnier site. Since this plant is native to Japan, it is found naturally in woodland settings. It flowers just a bit later than C. pauciflora with 2-3" racemes of from 6-12 flowers of clear yellow. It shows up so well because it flowers before most deciduous shrubs begin to leaf out. Truly one of the great woodland shrubs. Some of ours have reached 10', but 6' with a slightly greater spread is more common. Yellow fall color stands out nicely in its woodland setting as you can see in pictures below.
