Buddleja davidii

''Buddleja davidii'' , also called summer lilac, butterfly-bush, or orange eye, is a species of flowering plant in the family Scrophulariaceae, native to Sichuan and Hubei provinces in central China, and also Japan. It is widely used as an ornamental plant, and many named varieties are in cultivation. ''B. davidii'' is named for the Basque missionary and explorer in China, Father Armand David, who first noticed the shrub. It was found near Ichang by Dr Augustine Henry about 1887 and sent to St Petersburg. Another botanist-missionary in China, Jean-André Soulié, sent seed to the French nursery Vilmorin, and ''B. davidii'' entered commerce in the 1890s.

''B. davidii'' was accorded the RHS Award of Merit in 1898, and the Award of Garden Merit in 1941.
