Grafted Grevilleas

If you live where your preferred grevillea originates, then you likely have the kind of soil and climate that will help it thrive. You won't need a grafted grevillea. That's most of our grevillea range.
Grafted grevilleas are attached to (usually) Grevillea robusta, which is robust and resilient, ideal as a root donor. Any grevillea grafted onto its roots, can use those roots to grow in a wider range of soils and climates.
