Presenting Grevillea magnifica

Scientifically labelled Grevillea magnifica, this plant's unofficial common name is ‘Grevillea Pink Pokers’ which is an obvious nod to the pink flower spikes. It was previously recognised as a subspecies of Grevillea petrophiloides and is closely related to Grevillea oligomera.
Part of the Proteaceae family, this species is native to Western Australia and thrives in temperate to Mediterranean climate zones. In good conditions, this shrub will flower from winter to spring with spot flowering occurring all year.
Grevillea Pink Pokers' Growth Habits and Uses
Grown in gardens, this shrub will typically reach up to 4 metres tall and 2 metres wide with a medium growth rate. It can be kept smaller if grown in containers. The blooms will attract nectar-feeding birds and bees.
Grevillea pink pokers can be used for general garden shrubbery or gap filling. It will also make for an excellent feature plant if allowed to grow and spread. Alternatively, it will perform well if grown in patio container gardens.

Planting and Growing Conditions for Grevillea magnifica
These shrubs will perform best in an open position in the garden with good air circulation. Planting should be done in spring or autumn once temperatures are less hostile.

Fertilising Grevillea magnifica
While not needed, you can feed with a native plant fertiliser low in phosphorus during spring to boost overall plant vigour during flowering.
Add a healthy layer of organic mulch or pine bark mulch around the shrub in summer to maintain a cool environment for the roots.
