Does Allium multiply?

Why have my alliums disappeared?
The reasons alliums do not flower is usually because the bulb is not yet mature, planted too shallow, or planted at the wrong time of year. Drought, lack of sun and boggy soil can also prevent alliums from flowering.

A happy allium will self-seed freely. If you want to decide where your new plants will appear (rather than leaving it to chance and chaos), you can collect the seeds from the plant before they fall. Remove the heads (and stalks) as soon as they turn brown.
