This plant was incorrectly identified as Oreocallis wickhamii until 1991 when it was correctly described, named and transferred to the new genus Alloxylon by our own botanist, Peter Weston.

Alloxylon flammeum has a very restricted natural distribution, but is very accommodating when grown in cultivation.

A beautiful plant in cultivation with a spectacular floral display in spring.
Grows well in most soils as long as drainage is good and there is no water stress in dry periods. Plenty organic matter used as a mulch is most beneficial. Tolerant of moderate frost once established. Propagates readily from seed or cuttings.

Alloxylon flammeum is not known to be weedy.

Presently available from the Growing Friends.
