Cultivation details

Prefers a sunny position in a rich strong loam with abundant moisture at the roots[11, 200]. Grows well by water[11]. Succeeds in areas that do not experience prolonged winter temperatures below about -12°c[200], but young plants and the young shoots of older trees can be cut back by winter frosts[11]. A very ornamental tree[1], it fruits freely in Britain[11]. The leaves are sweetly resinous[245]. The deeply furrowed bark is aromatic[245]. Produces suckers profusely[98]. Plants in this genus are notably resistant to honey fungus[200].
