Allium flavum has been growing in my zone 6-A garden for five years. I look forward to its blooms each June/July. The lemon yellow flowers are about the size of quarter on the top of 10-12" stems. They make an attractive clump at the border's edge. The soil in my garden is naturally ACID, not alkaline.

Prefers full sun. Soil should be relatively dry. Flowers are a dainty yellow.
