allium

薤白（小根蒜）Allium macrostemon

Allium or FLowering Onions are grown for their huge rounded flowers. The allium comes in a range of colors, purple, white, pink or yellow. Flowering onions can be found in different sizes from the 4 foot tall Giant Onion with 6 inch balls of flowers to a 6 inch variety known as the Lily Leek. Their blooms only last for 2 weeks during the late spring - early summer period. You should plant in full sun in well drained areas. After the flower is finished blooming you can cut the flower stalk. Leave the leaves on the plant to help feed the bulb for next year. The allium requires little care once the plant is established. When the leaves turn yellow, you can cut them down at ground level. The allium is a bulb. Each year smaller bulbs grow around the parent bulb. You can gently lift the plant out of the ground and remove the smaller bulbs if
