Native: Most Clematis species are native to Asia, but they are also native to various regions across the Northern Hemisphere, including North America and Europe.
Description: Clematis plants are climbing vines with a wide variety of flower shapes, sizes, and colors. The flowers can be small or large, single or double, and come in many colors, including white, pink, red, blue, purple, and bicolors.
Growth Habit: Clematis plants have a diverse range of growth habits, including climbers, scramblers, and herbaceous perennials. Climbing varieties use their leafstalks to twine around structures for support. Scrambling types have a more relaxed growth habit and can sprawl or clamber over nearby plants. Herbaceous clematis forms bushy clumps and doesn’t climb or scramble.

They display an array of colors, from vibrant purples, pinks, and blues to soft pastels and crisp whites. Their exquisite flowers add charm and elegance to any garden.
Foliage: The leaves are usually compound with several leaflets, and they are arranged alternately along the stem.

Hardiness: Hardiness varies by species, but many are hardy in USDA Zones 4-11.
Uses: Clematis are popular in the landscape as climbers on trellises, fences, and walls, but they can also be grown as ground covers or through shrubbery.
Pollinators: Attracts bees, butterflies, and hummingbirds, serving as a food source for these beneficial insects and birds.
Toxicity: Clematis plants are toxic if ingested and can cause skin irritation.
