Introducing Grevillea Royal Mantle 

The Grevillea Poorinda Royal Mantle is just one of many Poorinda cultivars that were introduced during the 1970s and 1980s. The name Poorinda comes from a property in Gippsland, Victoria, that belonged to Leo Hodge.

He was the creator of various hybrids of Grevillea. The name comes from an aboriginal word and means ‘light’.  If you have a low wall that needs some of nature’s decorating, the Grevillea Royal Mantle will look great draped over it. 

The shrub flowers throughout the year, but its most generous blooms are during winter and spring. If the Grevillea Royal Mantle is grown in full sun, you should enjoy an abundance of red flowers that are toothbrush shaped. When the new leaves emerge, they are a brilliant shade of brown, bronze and red. 

Grevillea Royal Mantle is able to grow down very steep banks, and offers generous coverage that spreads quickly. The shrub can achieve a maximum spread of up to 6 metres. You’ll find this lovely shrub growing in most parts of Australia. It is both drought and frost tolerant.
