Is Grevillea 'Sandra Gordon' suitable for my climate and garden size?

Grevillea 'Sandra Gordon' is well known for its hardiness and adaptability, making it a great choice for a wide range of climates, especially in Australia. It thrives in full sun and well-drained soil, and it's drought-tolerant once established. This beautiful grevillea can grow up to 4–6 meters tall, so it's perfect for larger gardens, screening, or windbreaks. If you have a smaller garden, regular pruning will help keep it compact and manageable. Avoid planting in heavy clay or areas prone to waterlogging for best results.

How do I care for Grevillea 'Sandra Gordon' to keep it healthy and flowering?

Grevillea 'Sandra Gordon' is low maintenance but will reward a little care with masses of showy, large yellow blooms almost all year round. Plant it in a sunny spot with free-draining soil, and water regularly when young to establish roots. Once mature, it needs minimal watering. Lightly prune after flowering to maintain shape and promote more blooms. Use a low-phosphorus, native plant fertilizer for best results. Watch for signs of overwatering or poor drainage, as grevilleas don't like 'wet feet.'

What makes Grevillea 'Sandra Gordon' a great choice for attracting wildlife?

One of the standout features of Grevillea 'Sandra Gordon' is its spectacular sprays of large golden-yellow flowers, which are rich in nectar. These blooms are magnets for native birds—particularly honeyeaters—as well as butterflies and bees. By planting this grevillea in your garden, you'll not only enjoy a striking display but also support your local ecosystem with a steady supply of food for beneficial wildlife throughout much of the year.

The Grevillea 'Sandra Gordon' is a distinctive and highly ornamental Australian native shrub or small tree, cherished for its spectacular, large, golden-orange blooms and its graceful, weeping habit. This popular hybrid provides an extraordinary burst of warm color, blooming heavily through winter and spring and intermittently throughout the year. Its unique, dense, and slightly pendulous form makes it an excellent specimen plant or an effective, low-maintenance screen. As a highly drought-tolerant and bird-attracting choice, 'Sandra Gordon' is a standout feature for water-wise gardens, native landscapes, and any setting requiring year-round structure and vibrant color.

Botanical Characteristics

Characteristic	Detail
Scientific Name	Grevillea 'Sandra Gordon' (Hybrid Cultivar)
Common Names	Grevillea, Spider Flower (common genus name), Sandra Gordon Grevillea.
Growth Habit	A vigorous, dense, and slightly pendulous evergreen shrub or small tree with a distinctive weeping structure and rounded canopy.
Foliage	Features fine, deeply divided, bright green leaves that contrast beautifully with the warm flower colors. The fine texture adds visual softness to the landscape.
Flowers	Large, conspicuous, cylindrical racemes (toothbrush style). The color is a vibrant blend of golden yellow and apricot-orange, often appearing copper-toned in bud.
Flowering Season	Renowned for its long and heavy blooming season, typically running from late fall through spring, with scattered blooms possible in summer.
Nectar	Produces a rich supply of sweet nectar, making it a prime food source for native birds and hummingbirds.

Mature Size

'Sandra Gordon' is a versatile medium-to-large Grevillea that provides significant structure.

Height: Typically reaches 8–10 feet (2.4–3 meters) tall.
Spread: Achieves a broad 6–10 feet (1.8–3 meters) spread, developing its characteristic rounded and slightly weeping form.
Its size makes it ideal for use as a prominent focal point or screen.

USDA Hardiness Zone

This hybrid is reliably hardy in USDA Hardiness Zones 9–11. It performs optimally in hot, dry-summer conditions typical of Mediterranean and Australian climates. It tolerates light frost but requires protection from severe or prolonged freezing temperatures. It is an excellent choice for coastal gardens.

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, vibrant flower production.
Soil	Essential: Requires perfectly well-drained soil. Tolerates poor, sandy, or gravelly soils but is highly intolerant of wet feet and heavy, poorly draining clay.
Water	Highly drought-tolerant once established. Water deeply during the first year to encourage deep rooting. Mature plants require minimal supplemental water, perfect for water-wise landscaping.
Fertilizer	Crucial: AVOID all high-phosphorus fertilizers. Grevilleas are extremely phosphorus-sensitive. Use only a specialized low-phosphorus formula for Australian natives or skip fertilizing entirely.
Pruning	Benefits from light tip pruning throughout the year to maintain density and encourage new blooms. A harder prune can be done after the main spring flowering flush to control size.

Landscape Use

Specimen Plant: Used as a commanding focal point in the landscape due to its unique weeping habit and striking flower color.
Screening/Hedge: Its dense canopy provides a beautiful, soft visual screen or large, informal hedge.
Erosion Control: Suitable for planting on dry slopes and banks where its spreading root system can stabilize the soil.
Xeriscape Design: A reliable, colorful, and low-water cornerstone plant for native and arid-style gardens.

Wildlife Attraction

The large, nectar-filled flowers are a powerful food source, making this plant a phenomenal wildlife magnet. It is highly attractive to hummingbirds in North America and nectar-feeding birds elsewhere. Its extended bloom provides a crucial, reliable food supply, supporting local biodiversity.

Pest and Disease Resistance

Grevillea 'Sandra Gordon' is a hardy, robust plant with strong natural resistance to most common insect pests.¹ The main disease issue is fungal root rot, which is solely caused by poor soil drainage or overwatering—a risk easily mitigated by correct planting in porous soil.

Propagation

To ensure the resulting plant retains the superior floral color and distinct weeping habit of the 'Sandra Gordon' cultivar, propagation must be conducted using vegetative methods. Semi-hardwood cuttings are the preferred and most reliable technique, generally taken during the summer months.² Propagation from seed is not recommended as the hybrid traits will not be consistently reproduced.
