Jackman Clematis is a lovely, old-fashioned vine that is well suited to our urban landscapes. Showy deep purple-violet flowers cover the vine most of the summer. Once established, it is a fast grower to about 18 feet. Prune in the spring.
Plant in light, loamy, well-drained soil. There is an adage regarding clematis: "heads in the sun; feet in the shade," follow this! But there is a caution: don't place it where it will bake, for in our hot, dry summers, it is possible to get too much of a good thing. Timing of pruning depends on when the clematis blooms: as a general rule, spring and early summer blooming clematis ought to be pruned immediately after flowering; mid-summer and fall bloomers can be pruned in the spring. Clematis are twining and need support.
