How to collect allium seeds


Alliums are spectacular plants and it's worth saving a few seeds to sow in the spring to grow some more for the garden. The seeds will germinate quickly and reach flowering size in a couple of years.

How to do it


Cut the seedheads from your allium plants as they start to break open.


Bring them indoors and let them dry out.


Gently tap out the seeds and store them in labelled paper envelopes.

Our tip

If the weather is damp when you pick the seedheads from your alliums, they can be hung in a paper bag in the airing cupboard to dry out thoroughly before storing.

This spring for the first time ever I have started growing some vegies in pots and have a small raised bed with beans, peas and tomatoes. I have just acquired an allotment and as a complete novice I don`t actually know where to start or what to start growing. Any advice would be most appreciated. Thank you.

I have just taken all my saved alium seeds out of the airing cupboard. Going to sew them in the next couple of weeks.

HI there, I sent a comment the other month saying how I had grown 2 dozen alliums from seeds I found in the gardens of Queen Victoria,s Osbourn House while on honymoon there. IM sure Prince Charles would be "most amused" . I think his a grand chap. MY point is that I have not seen my comment posted or have I broken your code of conduct?. Kind Regards "Old Greenfingers"
