Physalis Germination

Seeds germinating in the growth chamber at BTI

It’s been 11 days since we planted our Physalis seeds here at BTI, and as of yesterday we are starting to see the first signs of germination. This is right on track as we expect Physalis seeds to take anywhere from 7-14 days to germinate (and maybe even longer!). It is too soon to estimate our germination rate, but from what we are seeing it appears to be promising. In a few weeks the seedlings should be ready for transplanting into bigger containers.

We have also heard from some of our project participants that they have had successful germination! Vanessa, who has been growing hers on the windowsill of her office since March 6th, has already had successful germination and some noticeable growth.

The next few weeks should be full of new growth and development. Although your seeds may have seemed slow to germinate, once they start growing they will grow quickly, with development times differing based on growing conditions. For reference I have included a picture of an eight-week old pruinosa plant grown under optimal conditions.
