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-summer.
Yes, ornamental onions are naturally resistant to deer and rodents. Their pungent scent, which is generally undetectable to humans, acts as a natural deterrent to these garden pests.
Absolutely. Alliums are well-suited for containers, provided you use a pot with good drainage and high-quality potting mix. Ensure the container is deep enough to accommodate the 4-6 inch planting depth.
The most important requirement is well-drained soil. Alliums are prone to bulb rot if left in standing water, so avoid areas that stay soggy or boggy after rain.
Yes, these are perennial plants. If planted in the correct hardiness zones (3-9) and provided with proper drainage, they will return and bloom reliably each season.
For the best visual impact, space the bulbs 4 to 6 inches apart. This density allows the plants to create a cohesive, architectural look in your beds or borders.
