I picked up some great bargains at our local garden centre last weekend. Some real treats including a variety of Anemones, Cosmos, Asters, Salvia-Mystic Spires. even hardy fushias, Japanese daisies, French Lavender, and lots of varieties of Dahlias. Can I plant them into the ground now? we don't have a green house, so difficult to know where to keep them from being killed off by frost. we do have a south facing garden though. Please help!
