barefeet , The morning glory, the sage , sound good I only have a red morning glory ,only one seed of the last of them came up this year ,
of course I have the weed things too
Milk Thistle
Stinging Nettle

Coneflowers have a antibiotic , the purple but I don't think I have seeds , as of right now I will see if I have half a dozen different seeds , you might like ..
