Because the very nature of this herb is 'weed like', Xanthium is just so easy to grow if left to it's own devices.
Sown in late winter it usually fruits in late summer. It is very fortunate that the seeds 'are' the remedy, because, if left alone Xanthium could be quite invasive.
Not a particularly attractive plant it is, none the less a boon for those who suffer from allergies that block the nose and cause the sinus's to swell and ache.
We make a tincture of the Xanthium seed for our own use but it is consumed, almost as a food by the Chinese.
If your climate is cold in winter and you do not want to go without, they will grow quite well in tubs or pots as long as they can drain.
