Snapshot is a post-emergent herbicide only, so it is not made to kill any existing plants. Geranium cinereum (ballerina) is listed as intolerant of over-the-top Snapshot applications, while the common weed Carolina geranium is prevented from germinating by using Snapshot. Geranium incarnum and Geranium subcaulescens are listed as tolerant plants of Snapshot. Since the exact species you mention is not listed as either tolerant or intolerant, we would recommend testing over a small area before treating around a large area of this groundcover, or selecting a different product for your needs.
If you would like to tell us more specifically which plants you are wanting to kill/prevent and which are the desirable plants, then we can better assist you.
