In your zone, hardy perennial geraniums should sail through the winter....some varieties will even retain foliage through the winter. And most species and cultivars will bloom in summer, not spring.

What kind do you have?

Unfortunately Gardengal48 I am not sure. When i contacted Brecks I was told that it was a super sak ( a bag of 20 plant roots having a number of different varieties and colors) but it would have 3 or more plantings of Cinereum Ballerina, Sanguineum Album, Johnson's Blue, Patricia, Ann Folkhard, or Karmina. Does this help? I know it will be only these varieties though.

Those varieties vary quite a bit in size so it would be worth trying to sort out the different types by eye, even if you don't know their names yet. Once they flower the Name that Plant Forum can help you. I'm not quite clear about why they were put in the fridge. You can plant them straight away and, as Gardengal48 said, winter will not faze them.

The bag said it could be fridged for 2 weeks if you couldn't plant them straight away:/

Interesting - not a technique I've come across with hardy perennials. Maybe it's not needed over here. I'd have thought it would do more harm than good shutting them in the dark and cold when they want to grow. Maybe it would be a good idea in the winter when they're dormant. Anyway yours seem to have survived and are growing. Gardengal48 - can you throw more light on this technique for me?

If it helps, they were purchased from Brecks. I just wanted to be sure they'd be ok bc they really have taken off and I've never grown geranium.

floral, it's a new one on me as well! But then I am not inclined to do much mail order at all (I can get virtually anything I want locally), so have limited experience with how they package things. I also would have thought that this would be a technique more typically used in winter when the plants were dormant than now......my hardy geraniums are still growing and flowering.

I'm also not a big fan of the grab bag method of bundling various cultivars together........but that's a personal thing. I want to know what I have or better yet, pick and choose what I get. But can understand using this if a large area to plant, or new to cranesbills and working on a budget.

pp, you're going to enjoy these plants. In my tiny garden now I only have a couple of varieties but in my old garden, I grew a couple dozen varieties and found them to be very useful, long blooming and pretty much trouble-free plants.
