Answer: Sweet Autumn Clematis (sometimes listed as Clematis paniculata or as C. maximowicziana) is usually offered along with other clematis for planting in the spring. (It was in the 1998 Burpee catalog, for example.) You might wish to order the upcoming Burpee catalogs for easy reference; you can do that through the Burpee web site (www.burpee.com) or by calling 800--888-1447. They can also take orders and give you up to the minute availability information on the telephone. Good luck with your search -- It's a great plant!
