More Seed Resources Seed Collecting Plants disperse their seed in almost as many ways as there are flower families.
Hardy geraniums have tiny built-in catalpults that literally throw seed when it is ripe.
Butterfly weed has silken parachutes to drift away on the wind. My preferred method to catching seed before it disperses is with pantyhose or nylon knee-highs. Since I was a bachelor for some years this method was quite time-consuming and expensive. Not the collection of the seed, for that was easy, but the obtaining of the pantyhose was the most difficult part. This involved meeting just the right individual, invitations to dinner with extensive wine lists, and the occasional collection expedition failure.
