Maybe, being a teen, s/he just moved on......
At any rate, I am chock to the gills with Asclepias tuberosa seeds from several years.
Dunno how long they are good for but I also DO HAVE some 2012 and 2013.
My seed collecting got ahead of my seed planting..... Late winter, I am going to just go sprinkle them everywhere, but milk jug "cloches" on them and see what comes up!
SO if you want some Asclepias t, let me know!
