Botanical Characteristics

Characteristic	Detail
Scientific Name	Grevillea 'Spirit of Anzac' (Hybrid Cultivar)
Common Names	Grevillea, Spider Flower (common genus name), Spirit of Anzac Grevillea.
Growth Habit	A highly vigorous, dense, upright evergreen shrub with a naturally neat and tidy structure, requiring minimal shaping.
Foliage	Features attractive, finely divided, dark green, lobed leaves that provide excellent texture and a rich background for the bright red flowers.
Flowers	Large, conspicuous, cylindrical racemes (toothbrush style). The color is a brilliant, fiery scarlet-red, known for its intensity and visibility.
Flowering Season	Celebrated for its remarkably extended bloom, often flowering year-round in mild climates, with peak production during fall, winter, and spring.
Nectar	Produces a significant amount of sweet nectar, making it a continuous and reliable food source for pollinators.

Mature Size

'Spirit of Anzac' is a medium-to-large shrub that offers substantial screening potential.

Height: Typically reaches 6–8 feet (1.8–2.4 meters) tall.
Spread: Achieves a dense, manageable spread of 4–6 feet (1.2–1.8 meters) wide.
Its upright, tidy form is ideal for formal or informal hedging where vertical structure is needed.

USDA Hardiness Zone

This high-performance hybrid is reliably hardy in USDA Hardiness Zones 9–11. It exhibits excellent tolerance for heat, drought, and coastal conditions. While it can handle light frost, it must be protected from prolonged or severe freezing temperatures.

Cultivation and Care

Aspect	Care Instructions
Sunlight	Requires full sun (at least 6 hours of direct sun daily) to ensure dense growth and maximum, year-round flower production.
Soil	Essential: Demands perfectly well-drained soil. Tolerates poor, sandy, or rocky soils but is highly intolerant of wet feet and heavy, compacted clay.
Water	Highly drought-tolerant once established. Water deeply during the first year. Mature plants are truly low-water and require only minimal supplemental water during extended dry spells.
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 a light prune after the main spring flowering flush to maintain a dense, tidy shape. It is easily clipped into a formal hedge or screen.

Landscape Use

Hedge and Screen: Its dense, upright habit makes it an excellent, fast-growing privacy hedge or windbreak.
Specimen Plant: Ideal for use as a dramatic focal point due to its intense color and continuous bloom.
Coastal Gardens: Performs reliably in coastal and mild-winter climates due to its resilience.
Xeriscape Design: A cornerstone, low-water, low-maintenance plant for native and arid-style gardens.

Wildlife Attraction

The rich, high-sugar nectar produced by the flowers is a powerful magnet for nectar-feeding birds, including hummingbirds in North America, and various native bees. Its year-round bloom provides a crucial, consistent food supply, supporting local biodiversity.

Pest and Disease Resistance

Grevillea 'Spirit of Anzac' is typically a hardy, robust plant with high natural resistance to most common insect pests. The primary disease concern is fungal root rot, which is solely a consequence of poor soil drainage or overwatering—a problem easily prevented by planting in well-drained soil.

Propagation

To ensure the resulting plant maintains the specific, superior vigor and scarlet-red flower color of the 'Spirit of Anzac' cultivar, propagation must be achieved through vegetative methods. Semi-hardwood cuttings are the preferred and most reliable technique, typically taken during the warmer months. Propagation from seed is not recommended as the hybrid characteristics will not be consistently reproduced.
