Flowers:

• Blooms: Abundant clusters of deep pink to crimson flowers cover the tree in spring, creating a spectacular display.
• Fragrance: The flowers may have a delicate fragrance that enhances the garden ambiance.

Fruit:

• Fruit: Small, spherical fruit that starts green and matures to red or reddish-purple in autumn. While edible, they are typically tart and often used for making jams or jellies.

Foliage:

Form and Size:

• Size: Typically grows 3-4 meters tall and wide, forming a rounded canopy.
• Habit: Upright and spreading when young, becoming more rounded with age.

Growing Conditions:

• Climate: Thrives in temperate to cool climates, suitable for many regions of Australia. It prefers mild summers and cool winters.
• Soil: Prefers well-draining, slightly acidic to neutral soil enriched with organic matter. Mulching helps retain moisture and regulate soil temperature.

Maintenance:

• Pruning: Prune in late winter to early spring to remove dead, damaged, or crossing branches. Light pruning after flowering can help maintain shape and promote air circulation.
• Fertilizing: Apply a balanced fertilizer in early spring to promote healthy growth and flowering.
• Pests and Diseases: Generally resistant to pests and diseases. Monitor for aphids, caterpillars, and apple scab, especially in humid conditions.

Notes:

• Hardiness: Hardy in USDA zones 4-8. In cooler regions of Australia, ensure protection from late frosts that can damage flowers and young leaves.
