(Sault Ste. Marie, Ontario Canada)
5-point tiny white waxy flowers with almost bugle-weed type foliage, low growing ground cover.
Hi Erin, this looks to be Sedum acre, but those aren't flowers - I believe that your clump has finished flowering and those are the dead flower head/seed capsules.
This is classed as a noxious weed in some areas because it spreads by seed and every single little piece of it that drops when it's stepped on.
The worst situation is when it gets into a lawn, where it's almost impossible to eradicate.
If you grow it in a patio situation such as between pavers, it's easier to keep under control.
Hope that helps,
