I've come into possession of some seeds from 2008 that for sentimental reasons, I'd like to give a shot at growing. Anyone have any general advice of tips specifically for older seed germination? They are Cape Gooseberries, so more of a warm weather-type plant.

You might check germination using the damp paper towel/baggie method. Not familiar with gooseberries, but many seeds have a pretty substantial life span. Good luck with your experiment--please come back and let us know how this turns out.

Cape Gooseberries are Physalis aren't they? If so I would soak them in warm water for a day or two the same as any other member of the Solanaceae family including Iochroma which are a similar size seed. Physalis seeds have a naturally low rate of germination in my experience.

You are correct! Thanks!
