To the eight people who would like some loofah seeds (The Quiet Life, Michelle, Tipper, Egghead, Vee, Melba, Ginger, and Betsy): Send your mailing information to me at firstname.lastname@example.org and I will send them right out.
Plant the seeds in spring in a place where they are free to grow, on a chicken coop, a fence, a trellis, the old bus shell out back.....and you will have plenty of Loofah and seeds of your own. To eat, you harvest at about 8 inches. To use them for sponges, wait until they turn medium brown, peel the skin off, and shake out the seeds. Some people bleach them. I don't see the point. Just leave them out in the hot sun for a while to dry them completely. You can cut the long sponges into shorter lengths or rounds to use for different purposes.
Egghead - You live in a cold climate, so the vine probably would benefit from a head start in a peat pot before setting outside.
The Quiet Life - The seeds will most likely do wonderful in San Antonio.
Ingeborg - I'll have to check how much it would cost to send seeds to Europe. I've never mailed anything outside of the US. If you would like to mail me your info, I will check.
Melba, Ginger and Betsy - I'll give you yours when I see you.
