Clematis are long-blooming vines that come in various colors, including white, blue, violet, purple, pink, red, or bicolor. They are hardy plants that can be trained to climb a wall, trellis, arbor, or other fixed structure. A wall or trellis covered in blooming clematis provides an architectural showpiece to any landscape or garden.
Clematis grows best in locations where it gets some full sun and some partial shade. It prefers areas where its roots are shaded and the flowering vines are in full sun. Well-drained, alkaline to neutral soil is ideal for successful growth.
Clematis varieties are divided into groups based on blooming time and other characteristics. When and how you prune depends on which group your clematis is from.
- Group 1 – Spring bloomers
- Group 2 – Repeat bloomers
- Group 3 – Summer or fall bloomers
