This species seem to be rare in cultivation, but Charles Williams of Caerhays Estate shared his experience cultivating this species. The estate’s ten year old plants initially required staking as they produced a single tall leading stem, before forming an umbrella-like head of top growth. Young plants were sparse flowerers but now flower reasonably well in comparison to other Styrax species. It flowers comparatively early, in late May or early June, and has good autumn colour. After 10 years the largest plant at Caerhays is c. 2 m tall with a crown 1.5 m across. (C. Williams, pers. comm. 2018).
