This light purple allium flower is a nice addition to the landscape, not only for its color but also for its globular shape.
Purple alliums are bulb plants. Like other spring-flowering bulbs, purple alliums need to be planted in the fall. The specific planting date in fall is determined by where you live. Plant in September if you live in zone 2 or 3. Plant in December if you live at the other end of the scale (warmer climate), in zone 8. For those in between, plant in October or November.
