This double flowered dogwood is also known as 'Plena' in the trade. It flowers in early spring with 6 to 8 white bracts instead of the typical 4. The doubling of the bracts is at the expense of true flowers so while there will be few if any fruits, the unpollinated flowers with their showy bracts last for an extra long time. Plants are susceptible to powdery mildew so plant them where there is good air circulation. Expect excellent purple-red fall color. Plant in full sun to part shade.
