Macrozamia riedlei
Also called Zamia Palm
Macrozamia riedlei, commonly known as a zamia or zamia palm, is a species of cycad in the plant family Zamiaceae. It is endemic to southwest Australia and often occurs in jarrah forests. It may only attain a height of half a metre or form an above trunk up to two metres with long arching fronds of a similar length. The giant cones amidst the crown of palm-like fronds contain edible seeds surrounded by red sarcotesta. The seeds are consumed by birds and animals, and can be a favoured part of the human diet when prepared correctly. M. riedlei benefits from a close association with bacteria that fix nitrogen, which also produce substances found throughout the plant that are toxic to some animals when consumed. The species is cultivated for ornamental use in urban and domestic environments.
Macrozamia riedlei has horticultural potential as a large container plant or specimen plant. It grows in well-drained soil and is sensitive to fungal attack. Large specimens can be transplanted. Seed germinates in 12 to 18 months.
Most of the genus Macrozamia are cultivated and M. riedlei is one of the better known species. The plant is well suited to rockeries and containers (Wrigley & Fagg, 2003). The trunk may reach two metres in cultivation, the pinnate fronds, dark green and palm-like, also reach or exceed two metres as specimens advance in age. The urban garden plant resembles the size of those seen in the field, one or two metres in height, although they are slow growing in their native habitat; container planting tend to produce smaller sized specimens. They respond well to applications of a general fertiliser, and favour full sun or partial shade. They are a recommended indoor plant, being tolerant of low light and temperature, slow growing and able to remain in a container indefinitely.
Occurring on lateritic soils, often in Jarrah forest, it is an endemic species of southern Western Australia.
