💛 Grevillea Honey Gem: Large, Fast-Growing Orange-Yellow Flowering Australian Shrub

The Grevillea Honey Gem is a magnificent, fast-growing Australian native shrub renowned for its vigorous growth and year-round display of spectacular, large, honey-colored flowers.1 This popular Grevillea hybrid (a cross between G. banksii and G. pteridifolia) is an evergreen powerhouse that quickly establishes itself as a striking feature plant in any garden. Its dense, fern-like, deeply lobed foliage provides a beautiful backdrop to the distinctive, showy, honey-yellow to apricot-orange blooms, which resemble elegant cylindrical brushes. A reliable source of color, the Honey Gem Grevillea is highly valued for its exceptional nectar production, making it an outstanding choice for attracting nectar-feeding birds and adding a lively, dynamic element to the landscape.2 It is also highly drought-tolerant and relatively low-maintenance, thriving in warm, full-sun environments.

    Growth Habit

    A vigorous, upright, and spreading evergreen shrub, often forming a dense screen or tall background specimen.

    Foliage

    Finely dissected, fern-like, deeply lobed leaves of a soft, deep green color, providing a lush, textured appearance.

    Flowers

    Large, cylindrical or brush-like flower heads, up to 6 inches long. Color ranges from vibrant orange-yellow to apricot or honey-gold.

    Flowering Season

    Exceptional for its prolonged flowering, often blooming profusely for most of the year, with a peak in the cooler months.

    Cut Flower Use

    Excellent and distinctive cut flower, adding texture and a bright, warm color to floral arrangements.

     

    Mature Size

    Grevillea Honey Gem is known for its rapid and commanding size, making it suitable for quick screening.3

    • Height: Typically reaches a substantial 10–15 feet (3–4.5 meters) tall, occasionally taller under ideal conditions.
    • Spread: Achieves a dense spread of 8–12 feet (2.4–3.6 meters) wide.
    • Its size is ideal for creating a fast-growing hedge or a large, vibrant backdrop.

    USDA Hardiness Zone

    This resilient Grevillea hybrid is well-suited for USDA Hardiness Zones 9–11. It performs best in a mild, warm climate and can tolerate light frosts once established, but requires protection from hard freezes.

    Cultivation and Care

    Aspect

    Care Instructions

    Sunlight

    Requires full sun (a minimum of 6 hours of direct sun daily) to ensure dense growth and maximum flower production.

    Soil

    Demands perfectly well-drained, slightly acidic to neutral soil. Thrives in sandy or gritty soils. Heavy, wet clay must be avoided.

    Water

    Highly drought-tolerant once established. Water deeply but infrequently. During the first year, water regularly until roots are set.

    Fertilizer

    Crucial: ABSOLUTELY AVOID all phosphorus fertilizers. Grevillea species are highly sensitive to phosphorus. Use a specialized low-phosphorus native plant formula or skip fertilizing.

    Pruning

    Responds well to light, regular pruning to maintain a dense shape and encourage new blooms. Prune after a main flush of flowers, removing spent blooms and cutting back to a desirable bud.

     

    Landscape Use

    • Screening/Hedge: Its fast growth and dense foliage make it an outstanding choice for a tall, informal, privacy hedge.
    • Specimen Plant: Used as a vibrant focal point due to its large size and prolific flowering.
    • Bird-Attracting Garden: An essential plant for gardens focused on attracting native Australian birds and hummingbirds with its rich nectar.4
    • Xeriscape: A highly successful, low-water, low-maintenance plant for water-wise gardens.

    Wildlife Attraction

    Grevillea Honey Gem is a premier choice for wildlife. Its abundant, sugar-rich nectar in the numerous flowers acts as a powerful lure, making it one of the best bird-attracting plants. It is frequently visited by hummingbirds (in North America) and native honeyeaters (in Australia), which are the primary pollinators.

    Pest and Disease Resistance

    This hybrid exhibits strong resistance to most common pests and diseases. As with most Grevilleas, the most common cause of decline is root rot or collar rot, which is almost always a result of poor drainage or excessive watering. Ensuring excellent drainage is the key to a healthy, robust plant.

    Propagation

    For commercial purposes and to guarantee the plant retains the vigorous growth habit, orange-yellow flower color, and other specific characteristics of the 'Honey Gem' cultivar, vegetative propagation is necessary. This is most reliably achieved using semi-hardwood cuttings taken during the warmer, non-flowering months, ensuring the clone is true to type.
