Willow herb EPILOBIUM PARVIFLORUM seeds wanted

Not he same as fire weed. Looking for these for medicinal purposes. I have some more interesting medicinal herb and vegetable seeds to offer. If you can swap plants that is even better as sometimes herbs are finicky to start, even if they grow like weeds, where we do not want them.
