Propagation
Sow fresh seed during early spring and pre-soak seeds in heated water 13º to 18ºC (55º-64ºF) for 24 hours. Seeds may require scarification (peeling treatment).

Semi hardwood cuttings taken during summer and apply bottom heat.
This plant has also been grafted on to G. robusta, using top wedge, whip and mummy grafting techniques.

Leaf: The variable flat silvery green leaves are (simple) linear to obovate with entire margins up to 170 mm (6¾ in) long overall or are divided into lobes (pinnatipartite) that are up to 130 mm (5⅛ in) long by 35 mm (1⅜ in) wide. They have an accumulate apex and a long slender petiole. The upper surface is slightly silky or glabrous with a prominent mid-vein and a lower surface is villous with a prominent mid-rib.
