Cracked pea gravel makes a great decorative gravel and can be used as a non organic mulch in flower beds . It will not rot down like mulch so is a long term solution.
Weed mat can be purchased to stop weeds growing from below.
It also can be used on a path or driveway. Due to it being an angular gravel it locks together when you stand or drive on it so will not roll about as with the round pea gravels.
Looks great with a cream paver to contrast against it.
