Hebe Heartbreaker

I am not sure what type of plants you are wanting and what your climate might be. If you are looking into cold frames, check out the raised beds and cold frames from Easy-Garden at www.easy-garden.com.

If the Hebes are very small it might be better to over-winter them in a cold frame, I think. They haven't got many weeks left (unfortunately) to get established before the first frost may threaten!
