Horticulture
A thicket forming, sparsely branched, evergreen shrub or small tree with stout shoots. The 5 to 11-lobed leaves, to 90cm (35in) across, scaly, mid-green above and felted pale green beneath, are clustered at the shoot tips. In winter the plant produces umbels, 1cm across, of white flowers in panicle-like inflorescences, to 50cm long, followed by spherical fruit, to 3mm across. It grows to 2.5m high by 2.5m wide.
Borderline frost hardy.
Brickell, C. (2003). A-Z Encyclopedia of Garden Plants. Dorling Kindersley. p.1029
Grow in any well-drained soil in full sun, sheltered from strong winds. In order to restrict the spread of established clumps, remove suckers at the extremities. Where top-growth is killed by frost, it maybe almost herbaceous, growing again from below ground. Prune in early spring, when dormant, removing misplaced or crossing shoots to maintain a permanent, healthy framework.
Brickell, C. (2003). A-Z Encyclopedia of Garden Plants. Dorling Kindersley. p.1029
To propagate, sow seed in containers in a cold frame in autumn. Remove suckers in spring or summer.
