Benefits for UK Wildlife

While grown mainly for its dramatic flowers, Sprekelia formosissima can still support garden biodiversity.

• Open flowers provide pollen for visiting insects
• Can attract pollinating insects when grown outdoors in warm conditions
• Works well in wildlife-friendly container gardens on patios or balconies

Plant it near other nectar-rich flowers to increase insect activity in your garden.

Where to Grow Aztec Lily

• Sunny patio containers
• Greenhouses or conservatories
• Warm, sheltered borders
• Exotic-style planting schemes

In much of the UK, containers make care easier. You can move the plant to a frost-free spot during winter.

Planting Tips

• Plant bulbs in spring after the risk of frost.
• Use free-draining compost with added grit.
• Position the bulb with the neck just above soil level.
• Place in full sun for the best flowering.
• Water lightly until growth appears.
• Feed during the growing season to build bulb strength.
• Reduce watering once the leaves fade and the plant goes dormant.

Leave bulbs undisturbed where possible. Over time, they may form offsets and produce more flowering stems.
