Bright periwinkle flowers bloom in early summer and develop into large, impressive clumps over time. Allium Azureum is lovely when paired with your favorite colored roses. 15 bulbs per bag. Bulb size 4-5 cm. Late blooming ornamental plants that work great with early flowering perennials. Do not plant too closely together since they multiply rapidly. Plant Alliums in full sun in early fall. Water well throughout the growing season.
Watering can resume in the spring. The plant self-seeds, so flowers should be deadheaded to inhibit their spread.
While alliums are fine for human consumption, they are poisonous to dogs and cats. Don't grow these in your garden if your pets can access them, and never give a dog or cat table food that has been seasoned with onion or garlic.
