Any suggestions on how to get Passiflora edulis seeds to sprout. I
received a bunch as a gift last fall, so far I've tried pete tabs and
sowing them straight into potting soil in 4 inch pots. So far nary a
sprout is to be seen. Should I pre-soak the seeds? score them, soak
them in alcohol or peroxide?

Urine works a treat.

Soak them in urine for 3 days.
