I'm looking for seeds of any native plant that attracts butterflies. I want to sow seeds for both host and nectar plants. Also would like to attract lacewings and other beneficial insects:>)
If you haven't already canvassed the Butterfly forum, here's a fellow from Radford VA area who has similar interests to yours.
Maybe he'll part with some of his bounty.
