Saxifraga – what kind though?

I got this plant a few years ago from a woman in a gardening group that I’m no longer in. She told me that it was a Saxifraga and that it liked full sun. I planted it in a sunny spot but didn’t look for any information about it – I just planted it and let it do whatever. For two years all it did was get leaves and get bigger. I figured that was all it did. Imagine my surprise earlier this spring when I saw it putting up stalks of buds! Woo!

So I go to look it up, and find that there are a ton of varieties. Woe. I have no idea what kind of Saxifraga it is. Help?

Thanks in advance!
