Growing Guide: Simple Care for Spectacular Results

• Location: Choose a spot with full sun or partial shade; ideal for borders, beds, or against walls for added support.
• Soil Requirements: Prefers well-drained, fertile soil with neutral to slightly acidic pH. Avoid waterlogged sites.
• Hardiness: Hardy throughout the UK (USDA zones 4–9). Mulch in colder regions for winter protection.
• Watering: Water regularly during active growth but do not allow bulbs to sit in soggy soil.

• Pests/Disease: Watch for lily beetle; remove by hand if seen. Generally disease-resistant if planted in well-drained soil.

Planting & Care Tips

• No staking required: Thick stems support heavy blooms even in exposed spots.
• Pruning: Remove spent flowers but allow foliage to die back naturally to feed next year's growth.
• Companion Planting: Pair with hardy perennials like hostas or ornamental grasses for layered texture and colour.
