couldn't hurt to try. The clover has white flowers and the puncture vine (aka goat weed or goathead weed) has yellow flowers, so even if you couldn't see the pattern of the leaves, you'd have a few days once you saw any yellow flowers, if any goat weed did come up.I've been trying to find a ground cover that would choke out the puncture vine, I wonder if the miniclover would do that?
