Prairie Monn says C10 so they need only ten days of cold, moist stratification. You can sow them at a time when you know they will get that outside. Legume seeds are better sown when young because they lose viability faster. Same with Apiaceae seeds. They'll probably still germinate. Let me guess, they came as freebies in a Prairie Moon seed order? They are like Verbena bonariensis, once you plant them, you'll always have them. There's also a Sensative Partridge Pea , Chamaecrista nictitans. I want seeds for those. I really love watching and listening to all the bumblebees on my Partridge Peas.

I planted some (also from Prairie Moon) a couple years ago, in a sunny bed. As I recall, I presoaked/nicked some, and left others untreated. No stratification. Didn’t seem to matter. They took a while to get going, but there were masses of them eventually.

To Jay’s point, I had even more last year, all self-seeded. I believe they came up a little earlier on their own — maybe the effect of stratification?

Can I just scatter them about at the back of the property

==>>> sure why not ... the only downside is.. will you recognize them when the sprout.. or will you end up weeding them out in some frenzy of weed killing.. lol ..

i would take 4 sticks found in the lawn ... and stick them in the ground.. and sprinkle the seeds within said defined area.. so if they do sprout.. you might think.. hey.. there are those sticks.. didnt i throw something down there.. and then when you focus and see a bunch of tiny babes that seem to look pea-ish.. just maybe.. you will remember what you threw down there .. or at least think.. hey.. i had some evil plan ... may as well wait and see what develops.. lol ...

i know it not precisely the question you asked.. but its a secondary consideration ...

HAHA yea, good point -- it would be DH tooling along on the tractor not paying any attention when he's cutting the grass in the pasture. Some stakes and caution tape should take care of that.

Yep, they were free Prairie Moon seeds.
