FAQs

When is the best time to plant these bulbs?

Allium 'Purple Sensation' should be planted in the autumn while the soil is still workable.

Do I need to lift them every year?

No, they are hardy perennials and can be left in the ground year-round provided the soil drainage is adequate.

Can I grow these in pots?

Yes, they thrive in containers, provided the pot has excellent drainage and is deep enough for the 15cm planting depth.

Are these bulbs deer or rabbit resistant?

Generally, Alliums are avoided by deer and rabbits due to their onion-like scent.

Should I cut the stems back after flowering?

You can remove the stem after the seedhead loses its ornamental appeal, but it is best to leave the foliage until it turns yellow so the bulb can store energy for next year.

Troubleshooting

Bulbs fail to emerge in spring

This is often caused by winter waterlogging; ensure your soil is well-drained and avoid planting in low-lying areas where water pools.

Flowers are smaller than expected

Bulbs may be overcrowded; consider lifting and dividing them every 3-4 years once the foliage has completely died back.

Pros and Cons

Pros

  • High visual impact with vibrant purple coloration
  • Loved by bees and essential garden pollinators
  • Very low maintenance once established
  • Provides multi-seasonal interest through seedheads
  • Excellent for cutting and floral arrangements

Cons

  • Requires very well-drained soil to avoid rotting
  • Foliage can start to yellow as the flowers emerge
  • Not suitable for heavy, waterlogged clay soil

Setup, Compatibility & Care

  1. Planting Time: Best planted in autumn before the ground freezes.
  2. Depth: Bury bulbs 15cm deep to ensure stability and proper root development.
  3. Spacing: Keep bulbs 10cm apart; overcrowding can lead to smaller blooms in subsequent years.
  4. Soil Conditions: Choose a spot with fertile, free-draining soil. If your soil is heavy, add a handful of horticultural grit to the base of each planting hole.
  5. Sun Exposure: Ensure they are in a position that receives full sun.
  6. Care: Avoid overwatering during the dormant phase. Once the foliage has died back naturally, you can tidy the area, or leave the architectural seedheads standing for winter interest.
