Ornamental Onion Growing and Maintenance Tips

Allium is easy to grow in any well-drained soil in full sun or partial shade. It will tolerate periods of drought relatively well. A. senescens is a bulb which multiplies by producing bulblets. These can be lifted, seperated, and used to start new plants. Division can be performed in either spring or fall.
