I would like clean, non-mildewed, dry yucca leaves for use in crafts. Only Chaparral Yucca (Yucca whipplei Torr.) from Southern CA, or Yucca Glauca or Narrow Leaf Yucca (Yucca angustissima). In exchange I offer Ponderosa pine needles for basketry; or seeds: Mixed Color Single Petal Hollyhocks, Rose Queen Cleome, French Dwarf Marigold, CA Giant Zinnia, Northern Sea Oats Grass(Chasmanthium Latifolium).

For the record, I've now grown all but agave harvardiana outside year round and they have all survived as long as you keep them dry in the winter. I cover them with clear plastic containers that have holes drilled in them to keep the air flowing to release humidity.

Thanks so much. My red ones just finished flowering & have about 8 seed pods that are green so the timing will probably be about the same. I'll contact you when my seeds turn brown & start splitting in a few weeks as a reminder since hers may be about ready, too. You & your friend are a "Blessing" to me & I'm "Thanking God" for you both, Trudy

A little late for this, but I would put it in the tub with some bleach water. and let it soak for a couple of hours. That should kill anything in it.
