Grevillea ‘Winpara Gem’ – Winpara Gem Grevillea

Grevillea ‘Winpara Gem’ – Winpara Gem Grevillea

Habit and Habitat:
Grevillea ‘Winpara Gem’ is a vigorous hybrid grevillea, believed to have originated from a cross involving Grevillea thelemanniana and Grevillea olivacea. Although not naturally occurring in the wild, it combines the resilience and floriferous nature of its parent species into a fast-growing, evergreen shrub. It thrives in sunny, open positions with well-drained soils and is highly adaptable to temperate and Mediterranean climates.

Place in Local Habitat and Ecosystem Distribution:
As a cultivated hybrid, ‘Winpara Gem’ fulfils many of the ecological roles of wild grevilleas. Its dense foliage provides refuge for small birds and insects, while its abundant nectar-rich flowers are an important food source for honeyeaters, spinebills, native bees and butterflies over an extended flowering season.

Planting Companions:
This grevillea combines beautifully with Callistemon viminalis (Weeping Bottlebrush), Correa reflexa (Native Fuchsia), Banksia spinulosa (Hairpin Banksia), Dianella revoluta ‘Little Rev’, Lomandra longifolia, and native grasses. These companions create a colourful, wildlife-friendly native garden.

Human and Wildlife Uses:
The vivid crimson-red spider flowers are produced in abundance and are highly attractive to nectar-feeding birds throughout much of the year. Its dense branching also provides excellent nesting and shelter opportunities for small birds. Widely used as a screening shrub or feature specimen, it is prized for its reliability, rapid growth and outstanding ornamental display.

Care Instructions:
Plant in full sun to encourage maximum flowering. ‘Winpara Gem’ prefers free-draining soils and is drought-tolerant once established. Avoid heavy clay and high-phosphorus fertilisers, as with all members of the Proteaceae family. Light pruning after flowering will maintain a dense, bushy habit and promote continuous flowering.

Size, Height, Width, Flower, and Leaf Characteristics:
Typically growing 2–3 metres high and 2–3 metres wide, this shrub develops a dense, rounded form. The foliage consists of narrow, olive-green leaves with a fine texture. Brilliant crimson to deep red spider flowers are borne in profusion for much of the year, particularly from autumn through spring, creating a spectacular display against the foliage.

Latin Etymology:
The genus Grevillea honours Charles Francis Greville, an English horticulturist and patron of botany. As a cultivated selection, ‘Winpara Gem’ is a registered cultivar name rather than a botanical species epithet.

Traditional Uses:
Although ‘Winpara Gem’ has no direct traditional Indigenous use, many naturally occurring grevillea species were valued as a source of sweet nectar, which was consumed directly from the flowers or soaked in water to produce a refreshing drink.

Planting Guidelines:
Select a sunny position with excellent drainage and allow sufficient space for the shrub to reach its mature size. Water regularly during establishment, then only during prolonged dry periods. Apply a coarse mulch to conserve moisture while keeping it clear of the stem. Ideal as a feature shrub, informal hedge, screening plant or wildlife attractor, Grevillea ‘Winpara Gem’ is one of the most dependable and rewarding grevilleas for Australian native gardens, providing colour and habitat throughout the year.
