I've been finding these little green (seed/berry) like objects in my garden for three years now.
This picture shows either a large variant or simply a later lifecycle stage of development.
At their smallest, they look artificial - kind of like nerds candy - almost too green to be natural. In the picture above, it is obvious that the item is a berry, but at the smallest sizes, my first thought was that it was fertilizer. And indeed, I would've continued to think that if not for two things:
- We re-mulched our garden two years ago, and didn't fertilize (nor have we ever, but this house is only 3 years old).
- When you squeeze even the smallest sized objects, they squirt juice or water.
When the larger berries are crushed, many little seeds come out along with liquid; and it looks almost like a miniature pickled tomato.
There is nothing in my garden that produces any kind of visible berries; and I've never seen one of these attached to a plant. That is part of what makes them so odd (and part of what made me think they were fertilizer); I always find them mixed (sometimes deeply) in soil or mulch.
If no one knows after a couple days, I'll go take a picture of one of the baby ones to help. Any thoughts?
Location: Brighton, MI (USA).
Update:. Here are some other shots. These are both flash shots because it is overcast today. These are also of the younger variant because I couldn't find any of the mature berries today. Hope this helps.
