I can't believe we are up to mystery seed #125 already. Some weeks it is hard to come up with something new, but then I look again at a common plant that I've taken for granted and there's our mystery seed 🙂
If you live in a warm climate, you may have seen these green fruit hanging on a shrub or small tree.
Over time they start to darken.
This is what they look like when they've fallen off the plant.
Any ideas what plant these belong to?
Edit: the answer is now posted.
