The same happens here iin Australia,the catalogues start coming just before spring. But we tend to get them all year round because we can grow lots more plants veges and flowers than most of the US and all of Canada,during most of the year. At our place I have Pansies all year round,because its cooler than down on the coast or out west. If I keep the water up to them they do well. I've started pruning my roses lightly in mid summer then a heavier prune the beginning of the last month of winter. If they are pruned too early they shoot then get frosted,which sets them back considerably.
