Description

A compact shrub growing to 1–2 metres high and wide with attractive green lobed leaves (similar to the cultivar 'Robyn Gordon'), its main horticultural feature is its flowering for 12 months of the year in warmer climates, such as Sydney and Queensland. The inflorescences are around 15 cm long by 9 cm wide and contain shades of orange, red and yellow.[1]

Cultivation

It has been very popular in Australian gardens since the 1990s, and widely planted in public spaces as well, though now there is an interest in ever smaller garden plants. The plant produces nectar and attracts both birds and bees. It likes a sunny, well drained position, will tolerate moderate frosts and grows well in a tub. Avoid using fertilisers that are high in phosphorus.[2]

Grevilleas, including this cultivar, can be pruned by up to one third in early spring.[3] This cultivar can be propagated fairly easily from cuttings.[4]

Toxicology

Along with a number of other grevilleas, this cultivar may cause allergic contact dermatitis for certain individuals who come into contact with it.

In the Public Eye

In 2003, Australia Post issued a 50c stamp depicting the cultivar.[5]

gollark: When he says "YOU WILL REGRET THIS", does that mean he's going to try and sabotage roads to get more money or something?
gollark: I am not aware of such an individual.
gollark: Well, if you don't start insisting that windows good FOSS bad again, sure.
gollark: We don't have a bot for that.
gollark: You can't really say "end of conversation" and expect people to agree with you. You *can* stop talking to them, but aren't.
