It's been a couple years since I first grew them. Some recently volunteered in some potted plants and are just now starting to bloom. Some poppy seed can remain viable for several years, possibly 10 or more.
I had one reach about 6 feet in height so don't count on 2 or 3 feet as the maximum height . It started blooming at the top and then sent out clusters of flowers from it's leaf axils , In descending order ( if my memory serves me correctly ) . I believe most poppies need sunlight to germinate and as their seeds are tiny , germination is best when seeds are scattered on bare soil. Soil may be lightly scratched , no furrows .Most poppies do not tolerate transplanting. Full sun is best.These guys are prickly .
