Many Alliums are grown for their ornamental qualities; however this cannot be said for all of them. Some are persistent weeds. Have a look at the different types of alliums:

  • The Invasive Type – White-flowered species cause the most problems. Not only do these include native species, but naturalised too. Some of these include:
  • Allium Paradoxum – This species spreads by seed.
  • Allium Subhirsutum – This has eye catching white flowers but self seeds.

Controlling Alliums

Try to avoid adding potted plants or soil with suspected ‘weedy’ alliums. Also a residual weed killer can be used around established woody plants or in uncultured areas.
