Growing & Care Guide
- Planting Time: Plant bulbs from autumn onwards for flowering from May to July.
- Location: Choose sunny spots with well-drained soil. Suitable for borders, rock gardens, and patio containers.
- Soil: Avoid planting in cold wet soils as the bulbs are prone to rot in these conditions.
- Watering: Moderate watering, particularly in dry spells, but do not overwater.
- Maintenance: No pruning necessary. Allow leaves to die back naturally for bulbs to store energy for next year.
- Feeding: A slow release fertiliser can be added to poor soils at the time of planting to improve fertility.
Garden Design Ideas
- Use taller alliums like 'Purple Sensation' or ampeloprasum as dramatic mid/back border features.
- Combine lower varieties such as moly or karataviense with sedums, ornamental grasses, or salvias.
- Fill containers for striking patio statements or weave through rockeries for naturalistic effect.
- Alliums combine well with perennials like Nepeta, Geranium, and Lavender for a pollinator-rich display.
