Cultivars A number of forms have been selected for cultivation, including the following: •
Allyn Magic, a compact form of var.
minor with greyed-orange new foliage bred by Noel Jupp of
East Gresford, New South Wales. •
Elizabeth Isaacs (also known as 'Variegata'), a slightly smaller cultivar that has new growth flushes with a combination of pink, green, cream and cream-margined leaves. •
Firescreen, a select, fast growing, broad leaf form. Glossy, copper–red new foliage growth is encouraged by a regular prune and feed, maturing to mid green. Selected for hedging from 1.2 m high, Firescreen has a semi-pendulous, dense habit, a short leaf internode and holds its foliage all the way to the ground. Unpruned height over 6 metres. Can also be used as a pot specimen for topiary or as a standard. Firescreen tolerates full sun to shade, windy conditions, heat waves and cold to −2 °C and it is psyllid and borer resistant. Bred by Tracey and Stuart Knowland of Bangalow Wholesale Nursery NSW, with
plant breeders' rights granted in 2010. •
Hedgemaster is a compact shrubby form reaching a metre (3 ft) tall and 0.5 m wide. It has a bushy dense habit and small leaves, and can be used in

Don Burke [Note: plant breeders rights since terminated]. •
Red Head, a select, broad leaf, compact tree form. Glossy, burgundy-red new foliage is encouraged by a regular prune and feed, maturing to very dark green. Unpruned height 8m+. Selected for compact, bushy form suitable for pleaching, topiary, standards or as a stand-alone tree in urban areas. 'Red Head' tolerates full sun to shade, windy conditions, heat waves and cold to −2 degrees. 'Red Head' is psyllid and borer resistant.
