Dianella Caerulea 'Cassa Blue'

• Native to eastern Australia, Dianella Cassa Blue is a compact flax lily cultivar developed for garden use and container growing.
• Features attractive blue berries that follow small blue flowers, creating ornamental interest through multiple seasons.
• Grows in a neat clumping habit with arching strappy leaves, making it perfect for modern landscaping and native gardens.
• Popular with gardeners for its low maintenance requirements and ability to attract native wildlife while providing structural interest.

• Water weekly during growing season, reducing to fortnightly in winter - check soil moisture before watering as overwatering is the main cause of problems.
• Position in partial shade with morning sun and afternoon protection - avoid deep shade which reduces flowering and fruiting.
• Plant in well-draining native plant mix or add sand and organic matter to improve heavy clay soils.
• Feed with low-phosphorus native plant fertiliser in spring and autumn - avoid high-phosphorus fertilisers which can damage native plants.
• Prune spent flower heads to encourage more blooms and remove old foliage in late winter to refresh the plant.
• Maintain good air circulation and avoid overhead watering to prevent fungal issues in humid conditions.

• Provide bright indirect light to partial shade - too much direct sun can scorch leaves while too little light reduces flowering and fruiting.
• Water regularly during establishment then reduce to weekly deep watering - allow soil to dry between waterings as this plant prefers drier conditions.
• Maintain moderate humidity and good air circulation around the plant to prevent fungal issues.
• Tolerates temperatures from 5°C to 35°C - protect from frost when young and provide shade during extreme summer heat.

• Scale insects may appear on foliage - treat with horticultural oil or insecticidal soap applied weekly until cleared. Remove heavily infested leaves to prevent spread.
• Root rot can occur in poorly draining soils - ensure good drainage and reduce watering if soil stays soggy. Yellow lower leaves often indicate overwatering issues.
• Leaf spot fungal diseases may develop in humid conditions - improve air circulation and avoid overhead watering. Remove affected foliage promptly.
