Grevillea x 'Moonlight' carries very large creamy-white toothbrush flower spikes almost continuously through the year, each one up to 20 centimetres long and heavily worked by honeyeaters. Few native shrubs flower this hard for this long.
'Moonlight' grows to 4 to 6 metres tall but only around 2 metres wide at 20 to 40 centimetres per year, giving a tall narrow frame clothed in fine silver-green divided foliage. That upright habit suits narrow garden beds, screening along a fence line, or a single feature in a large pot.
This Australian native grows in full sun to part shade, tolerates light to moderate frost once established, and is highly drought tolerant. It needs free-draining soil and low-phosphorus feeding, and rewards a light prune after each main flowering flush with denser growth.
Frequently Asked Questions
About Grevillea 'Moonlight'
How tall does Grevillea 'Moonlight' grow?
'Moonlight' grows to 4 to 6 metres tall and only around 2 metres wide, giving an unusually tall narrow form for a grevillea. It suits narrow beds and screening positions.
When does Grevillea 'Moonlight' flower?
'Moonlight' flowers close to year round, with the heaviest flushes in spring and autumn. The large creamy-white toothbrush spikes can reach 20 centimetres long.
Does 'Moonlight' attract birds?
Yes. The nectar-rich flowers are a magnet for honeyeaters and other nectar-feeding birds, and the dense fine foliage provides shelter for smaller species.
How fast does 'Moonlight' grow?
It grows at a moderate 20 to 40 centimetres per year, reaching a usable screening height within four to five years in a warm free-draining position.
What soil and feeding does 'Moonlight' need?
It requires free-draining soil and will not tolerate waterlogging. Use only low-phosphorus native fertiliser, as grevilleas and other Proteaceae are damaged by high-phosphorus formulations.
Is Grevillea 'Moonlight' drought tolerant?
Yes. Once established it is highly drought tolerant and needs only occasional deep watering through extended dry spells.
Should I prune 'Moonlight'?
Yes. A light prune after each main flowering flush keeps the plant dense and prevents it becoming leggy at the base. Avoid cutting back hard into bare old wood.
