How far along to harvest viable allium seeds?

The alliums in question have dead foliage and the flower heads are now only green seeds. If I remove the head at this point will these seeds be usable for this Fall or next spring or do I need to leave the allium head alone ie on its stalk in the ground until the seeds turn brown?
