A week or so ago 6 of my grandilforas flowered so I pollinated the flowers by basically going along like my toothpick was a small bee and went from one to another. I now have 3 plants with swelling seedpod. I know my other temperate pings (P.macroceras) will drop their seeds and they will germinate without stratification so I was wondering if I need to collect the grandiflora seeds and plant them next spring or plant them as soon as the seedpods develop?
