I was already getting worried as the Green Horn and Ventergreen seeds took their time germinating. But after a couple of rainy days there they came. I'm sure they would germinate even better in the fall: these were harvested in February and might still be a bit too fresh.

These were a product of selfing and I actually didn't expect anything to germinate. We'll see how they'll develop.
