Alyssum

• Alyssum originates from the Mediterranean region and has naturalised in temperate zones worldwide. Its botanical name comes from the Greek word meaning 'without madness', as it was once believed to cure rabies.
• The plant forms low mounds 10-15cm high with tiny four-petalled flowers clustered in dense heads. Its sweet honey fragrance intensifies in the evening, attracting butterflies and bees.
• Gardeners love Alyssum for its ability to self-seed and return year after year with minimal care. It's ideal for softening hard edges, filling gaps between pavers, and creating romantic cottage-style gardens.
• The cascading growth habit makes it perfect for hanging baskets, window boxes, and spilling over retaining walls. Flowers appear in abundance, often covering the foliage completely.

• Water Alyssum when the top 2-3cm of soil feels dry, typically 2-3 times weekly in warm weather. Reduce watering during cooler months and avoid waterlogged soil which causes root problems.
• Position in full sun for best flowering, though plants tolerate partial shade in hot inland areas. Morning sun with afternoon protection works well in warmer Australian climates.
• Plant in well-drained soil enriched with compost; Alyssum tolerates poor soil but performs best in moderately fertile conditions. Add sand or perlite to heavy clay soils.
• Apply a weak liquid fertiliser every 4-6 weeks during the flowering season to maintain continuous blooms. Avoid high-nitrogen feeds which promote leaves over flowers.
• Deadhead spent flowers regularly or give plants a light trim to encourage repeat blooming and maintain a tidy appearance. Cut back by half if plants become leggy mid-season.
• Alyssum requires no special humidity and thrives in average garden conditions. It handles dry periods well once roots are established.
• Plant in autumn in warm climates for winter-spring colour, or in spring in cooler regions. Allow plants to self-seed for effortless returns each season.

• Plant Alyssum in full sun to partial shade, though flowering is most prolific with at least 4-6 hours of direct sunlight daily. In hot Australian climates, afternoon shade prevents stress.
• Water moderately, allowing soil to dry slightly between waterings; Alyssum is quite drought-tolerant once established. Reduce watering during winter when growth slows.
• Feed lightly with a balanced liquid fertiliser every 4-6 weeks during active growth to promote continuous flowering. Over-feeding reduces blooms and encourages leafy growth.
• Trim back by one-third after the first flush of flowers to encourage a second wave of blooms. This keeps plants compact and tidy throughout the season.
• In warm climates, Alyssum performs best as a cool-season annual; plant in autumn for winter and spring colour. In cooler regions, it may bloom from spring through summer.

• Aphids can cluster on new growth and flower buds; spray with a strong jet of water or apply insecticidal soap. Check plants regularly during cooler months when aphids are most active.
• Powdery mildew may appear as white patches on leaves in humid conditions; improve air circulation and avoid overhead watering. Remove affected foliage promptly.
• Overwatering causes root rot and yellowing leaves; ensure soil drains freely and allow the surface to dry between waterings. Alyssum prefers slightly dry conditions.
• Leggy growth occurs in too much shade or when spent flowers aren't removed; trim back regularly and ensure plants receive adequate sunlight. Deadheading encourages bushier growth.
