This photo of Clematis tangutica 'My Angel' beautifully illustrates the three stages of a clematis. The bud is full and eager as a child for their first day of school. Then there's the velvety flower, glistening delightfully with its elegant anthers. And finally, it shows the woolly, silvery seed head.
The 'My Angel' clematis is a fast grower, so some space is required. It looks great against a wall or pergola, but it also thrives between shrubs.
