#ProPlantTips for Care:
These showy and whimsical Alliums reach their full potential in full sun and fast-draining soil. Fall-planted bulbs need moderate moisture needs. Any soil type is suitable so long as it is not soggy and add bulb fertilizer to each hole for best results. Their blooms last for weeks and they naturalize and spread over time unless you deadhead after the flowers fade. Deadhead after flowers fade, but let the leaves remain so they can make food for the bulb and next year's flowers! Once the foliage yellows in the summer or fall, you can then prune it to the ground.
- Full Sun For Strongest Growth
- Well-Drained Soil
- Moderate Moisture Needs
- Deadhead After Flowers Fade & Prune Mounds After Leaves Yellow
- Deer Seldom Bother Them
