Origin of Scientific Name

Macros - Greek, meaning 'large'.

Fraseri honours Charles Fitzgerald Fraser (1883 - 1951), who was a Western Australian surveyor and pastoralist.

Description

This cycad is endemic to Western Australia and can be found as far north as the Geraldton Sandplains, to the southern contingent of the Swan Coastal Plain.

With a show of spectacularly structured fronds that can grow up to three metres long, at the right time of year, you may also be able to spot large conical fruit, with the bright red colour of the seeds contrasting against the evergreen habit of Macrozamia fraseri.

This plant is slow growing and the trunk of older plants can be up to one metre high, but are more often trunkless. Often these plants bear the blackened marks of a fire on their trunks – a testament to their hardy nature.

This species produces separate gendered plants with the female plant producing the large toxic red fruits. The Tranes genus of Weevil plays an instrumental part in the spore transfer between male and female cones. Once fertilised, the female cone produces vibrant red seeds which are poisonous, as Dutch explorers found to their cost when they first set foot on Perth soil in 1697.

Ancestors of the cycad existed 250 million years ago. It's tough sharply pointed and leathery fronds protected the plant from grazing dinosaurs.

There are 283 known species of cycad worldwide with 76 species in Australia, seven species in Western Australia.

Horticultural tips

  • Macrozamia fraseri grows well in sandy, free draining soil, although it is not common to see it in cultivation.
  • Plant in moist soil, in a sunny position. This plant has origins in a Mediterranean climate, where rainfall occurs in the winter months. It is also quite tolerant to cold temperatures.
  • This species is often reclaimed as a result of 'urban sprawl' and can be purchased as a mature plant for instant effect in your garden.
