I have some penstemon plants here that make stinky seeds--like PU catbox stink. The plants have NOT been spritzed by cats--it's their seeds that stink that way. Yuccch.
Does anyone have some suggestions for descenting them? I've already tried placing them in the sun on a plate and airing them--but it doesn't seem to have changed their scent. I don't want to spray them with lysol and dry them again--I'm concerned with sending seeds that have any artificial additives coating them.
