That “alien grenade” description is actually pretty accurate 😄 — what you’re seeing is very likely a magnolia seed cone from a tree in the genus Magnolia.
When magnolia fruits mature, they form a woody, cone-like structure. Inside are bright red (sometimes orange-red) seeds that pop out and hang by thin threads. The fuzzy or knobby texture and the sudden appearance of those vivid seeds make them look unusual—almost artificial.
A few things that match your description:
- Cone or grenade-like shape
- Slightly fuzzy or bumpy exterior
- Bright red “berries” (they’re actually seeds) emerging or dangling
- Found under a tree, especially in late summer to fall (though timing can vary by climate)
Those red seeds are attractive to birds, which help spread them.
If you want to double-check, look up at the tree—magnolias usually have:
- Large, glossy leaves
- Big, fragrant flowers (white, pink, or purple depending on species)
It’s harmless, just part of the tree’s reproduction cycle. If you’re curious, I can help identify the exact magnolia species if you describe the tree or share more details.
