Know before you buy
These bulbs should be planted in the fall. This allows them to establish their root systems during the cooler months before they bloom in early to mid-spring.
They are excellent for container planting. Because they stay relatively compact at 6-10 inches tall, they work well in pots, window boxes, or as a border in larger arrangements.
These bulbs are quite versatile regarding light. They will perform well in full sun, partial sun, or even full shade, making them a flexible choice for various spots in your garden.
Yes, they are considered deer and rabbit resistant. While no plant is entirely immune to hungry wildlife, these are generally avoided by common garden pests.
They require well-drained soil to prevent the bulbs from rotting. If you have heavy clay soil, consider amending it with organic matter or planting in raised beds to improve drainage.
For the best results, space the bulbs 15.24 cm (6 inches) apart. This provides enough room for the plants to spread and create a lush, full appearance when they bloom.
