In cooler northern gardens, clematis can rival the morning glory for prolific blooming and beauty. Unlike morning glories, clematis blossoms are sturdy and can last several days. They bloom in late spring and often again in autumn, if the weather stays mild. I've even seen them bloom as late as January, when frost was late. They have attractive foliage, and are vigorous growers in the right conditions.

Clematis come in a number of sizes and colors, but the most common are purple, white, magenta, and pink. They all seem to do equally well, so there's no reason to choose basic purple unless you want to. Many people plant several different kinds.

Clematis benefits from cooler weather, sunshine, and a location where it can climb. It likes to have cool roots, and appreciates a rainy climate. Xenia Fields recommends an application of hydrated lime and maybe some well rotted manure in the spring.
