Sinojackia xylocarpa

Similar to S. rehderiana, this is also a large Chinese shrub or small deciduous tree, but with slightly larger elliptic foliage and bigger fruit. The pendulous flowers, in May and June, are pure white and dissected into 4 or 6 lobes, spreading wide to show the yellow stamen. They are usually borne in short racemes, en masse below the branches. For a lime free soil.
