Other Features:

Description: Although we have been growing Corylopsis pauciflora, Buttercup Winterhazel, for several years, we have also added to our list C. spicata - Spike Winterhazel. This is a more upright open shrub with larger flowers; racemes that are approximately 2 inches long, of pale yellow flowers very early in the spring. This shrub might reach 8 feet in height and probably the same width. The foliage is good clean foliage similar to that of a witchhazel, but, itís the yellow flower racemes nodding very early in the spring wind that make this shrub valuable for the shrub border. C. spicata is a bit more hardy than the other, being listed as a Zone 5 plant, whereas C. pauciflora is listed only to Zone 6. Corylopsis are good plants to feature in the garden center very early in the spring - they are plants that will draw early customers to your sales yard.
