I pull up the plants late in the summer, before the pods start to decompose and tear, but when they are good and dry and relatively easy to strip. I take the uprooted plants to whatever part of the garden or landscape where I'd like them to grow in the future, and shake them rather briskly (not hard enough to break the stems.) If you pick them on a nice dry day, the seeds will fly! Most, but not all, are shed in this manner, and the remainder must be stripped by hand. Honesty is a biennial. It takes two years to mature. The first year after shaking branches of it in a particular area, you get nice little soft round plants that make a nice groundcover under and around other plants. They're easy to pull up if they sprout in the wrong place. I generally leave as many as possible in place. The second year, in the spring, each of the little plants sprouts into gorgeous bloom - you may have to thin them out at this time to allow enough space for them to develop. when the blooms fade, the seed pods start to develop, and the plant becomes more and more unattractive. This is when I yank out almost all of them, leaving a few in inconspicuous places to mature and dry. When rubbing the pods between my fingers, I work, for the most part, in an area where I'd like future plants to grow. However, I "clean" some of the branches over a piece of newspaper so I can collect and save the seeds. I store them for a year, and then scatter them in late summer. Otherwise you'll get silver pennies only every other year. this assures an annual crop.

They don't last very long no matter what you do.You can try keeping them dry and around 70 degrees is my guess. They will die evenually from the dry. There are some palm seeds that will take a year or two to germinate but these are not one of them.

Sue I store mine in a plastic bag in the freezer. I also use it once or twice a year (but I do like to eat it like candy sometimes and its good if your stomach is upset). Unfortunately, today when I went into the freezer to take it out (for my sweet potatoes tomorrow) I found that I'm out of it and my store didn't have any and I just didn't feel like driving way over to the other store to see if they had it. Darn it! Now I have to decide on something else to do with the sweet potatoes.

To dry allium heads, cut the flower head as soon as they begin to break open, bring them indoors and hang them upside down to dry.
