Remove suckers during spring and pot-up into a deep container or plant in situ. Keep moist during establishment.

Note:
In cold climates this cycad is grown in a conservatory or glasshouse and is planted in deep pots with equal parts of loam and coarse sand with some granulated bark and the addition of slow-release fertiliser. It should be placed in a bright filtered light, humid position and watered regularly during summer.

Botanic information
Leaf: The large arching glossy dark green pinnate fronds are up to 2 m (6 ft) long and have numerous leathery textured oblong to oblong-ovate leaflets with several spiny lobed teeth towards the apex that are up to 150 mm (6 in) long by 50 mm (2 in) wide. The overlapping coppery-brown new leaflets are slightly pubescent, becoming glabrous as they mature.

Flower: The cycad is dioecious and the 1-6 reddish cylindrical male cones that are up to 500mm (20 in) long by 100 mm (4 in) in diameter and appear in a cluster on a peduncle up to 30 mm (1⅛ in) long. The 1-5 yellowish-orange sessile ovoid female cone is up to 500mm (20 in) long by 250 mm (9¾ in) in diameter and appear at the centre of the whorled leaves during summer. 

Note:
Both the male and female cones appear on the plant consecutively.

Fruit: The orange-yellow female cones produce masses of flesh covered seeds that are up to 50 mm (2 in) long and are bright orange to red in colour and when mature they fall to the ground. the seats are disbursed by birds and monkeys that discard the seeds once they have eaten the fleshy covering. The seeds are toxic and should not be eaten.
