Hydrangea angustipetala f. formosa
Hydrangea, Willow leaf
This deciduous shrub is a Hydrangea but has willow-like leaves. Flowers are tiny yellowish fertile flowers with scattered marginal white fading to yellowish fertile florets. This is a new and little-known introduction which we obtained from Tony Avent at Plant Delights Nursery. It is native in forests in Taiwan at relatively high elevations. Try it in semi-shade with good soil that is well-drained but kept moist. Famous horticultural expert and plant breeder Dr. Michael Dirr has recently written of his interest in cutlivating this plants and enthusiasm for using it in his plant breeding work.
