Grevillea ‘Orange Marmalade’ is a hybrid whose parents are said to be Grevillea glossadenia and Grevillea venusta and appeared in a Brisbane garden.
Grevillea ‘Orange Marmalade’ is an open shrub that has reached a height of two metres in a sheltered position in our garden.
Elliptical leaves are about seven centimetres long with prominent veins. Leaf shape and appearance are similar to that of the rare Grevillea shiressii.
Large flowers are carried in terminal racemes and are an unusual orange colour with red styles and resemble the colour of orange marmalade hence the name. Flowers are carried for many months and are attractive to honeyeaters particularly Eastern Spinebills.
Both parents, of this colourful hybrid, are Queensland species.
To grow ‘Orange Marmalade’ in our frosty garden requires a sheltered area. We tried a plant in an exposed part of the garden. Unfortunately, this specimen never made it through the first winter. The survivor is thriving against the north facing wall of the house where Eastern Spinebills are constant visitors.
Grevillea “Orange Marmalade” is a striking plant.
