Cultivation Notes: Prefers a good deep fertile loam which can be on the stiff side[1, 11]. Young plants tolerate reasonable levels of side shade[200]. Tolerates moderate exposure, surviving well but being somewhat stunted[200].
A very ornamental plant[1], it grows well at Kew, occasionally producing fertile seed[11]. It prefers warmer summers than are usually experienced in Britain, trees often grow poorly in this country and fail to properly ripen their wood resulting in frost damage overwinter[200].
The tree flowers on new growth produced in spring, the seed taking two summers to ripen[229].
Intolerant of root disturbance, trees should be planted in their permanent positions whilst young[11].
Hybridizes freely with other members of the genus[200].
This species is notably resistant to honey fungus[88, 200].
