As climbers, Clematis are unsurpassed in their long flowering presence, their rich diversity of flower shapes, their wide array of colors and tolerances in terms of exposure and climate. It is no wonder they are so popular! From tree huggers to container varieties, there is a Clematis for every garden and flowers for almost every month of the year!
Members of the Ranunculaceae family, Clematis include more than 300 species and hundreds of hybrids. Many make terrific container plants, especially if trained up an obelisk or a small trellis.
- When choosing clematis cultivars for your container, look for compact plants that carry their magnificent flowers over a long period.
- Select slow-growing varieties and avoid vigorous varieties (e.g. Clematis montana) which would require too much room for their roots to grow. Generally speaking, any clematis that grows up to 8 ft. (2 m) will thrive in a container.
- Growing a clematis in a container above ground decreases its winter hardiness by a full zone. As an example, if you live in USDA zone 4 and wish to grow Clematis 'Josephine' in a container (USDA zone 4-11), you are changing it into a USDA zone 5, and it may not survive, although this would not be an issue if planted in the ground.
There are so many clematis varieties that finding the best one for your needs might be a daunting task. To assist you in selecting the right plant, here is a list of great clematis vines for your containers.
