Heptacodium miconioides

The 'Seven Son Flower of Zhejiang'. Only introduced from China in 1981 this vigorous, easy, very hardy and attractive large shrub has proved its worth. The foliage has 3 prominent veins and each leaf curls under the branch creating a tube effect. Clusters of scented white starry flowers are borne in late summer, the calyx turning red if it's warm.
