Answer: Unfortunately morning glories are not perennial in cold climates. They begin to bloom in mid summer and then continue until frost, so they do bloom for many months. Planting too early will not help them bloom sooner -- they really prefer hot weather. You may find however that they will self sow and thus come back on their own from year to year and thus seem almost like a perennial. Burpee (800-888-1447) offers morning glory seeds.
Although the amount of bloom would not equal that of a morning glory, some clematis such as the Jackman Clematis will bloom off and on all summer if they are kept in vigorous growth and if the weather that year is to their liking, meaning not too hot or dry. To enhance their blooming, provide them with ample water and a cool root run with rich soil. Clematis plants are widely available at garden centers and through catalogs such as The Compleat Garden Clematis Nursery, 217 Argilla Rd., Ipswich MA 01938 tel. (508) 356-3197 or Carroll Gardens 444 East Main St., Westminster MD 21157, tel. (800) 638-6334.
