Taboule, I planted some leggy Peacevine seedlings in a compost pile one year.
"Hippie style" we called it. Laid the long stems down and covered with earth let them come what may. It was a good summer and they roamed happily around there and ripened a nice lot of cherries in September.
And the spring after that my Mom asked for a Peacevine and I said sorry, I didn't start any. Then I went out and lo behold a little seedling in the compost pile!! I potted it up and gave to her. What mother wants....mother nature provides.
It was true to seed, too.
