Plant of the Week: Clematis
Care Tips and 2024 Availability!
We ❤ clematis for several reasons, namely, because there are SO many beautiful colors and shapes to choose from! We always struggle to decide which to grow each season and are extra excited for this year’s selection. Clematis can be a bit finicky to start in a greenhouse setting, especially in cooler months, but we altered our growing schedule and techniques and the plants look extra healthy and lush as a result! Clematis are most often grown vertically on a trellis or arbor, but many varieties also do well in pots or sprawling over a wall.
CLEMATIS GROWING TIPS
Clematis has a few specific needs that, once met, ensure a healthy, heavily blooming perennial vine year after year. Clematis are said to like having their “heads in the sun and feet in the shade”. Mulching around the roots will help keep the soil cool, as will the foliage of a low-growing perennial placed in front of this vine. The key is really maintaining moisture around the roots, as well as preventing hot afternoon sun from fading the blooms.
Choose an area with plenty of morning and midday sun, but some protection from direct sunlight in mid to late afternoon (or if in sun all day, preferably northern or eastern facing). When planting clematis, make sure to dig a large hole (up to 2 feet wide and deep), and amend the soil to improve drainage and give it some extra nutrition (try mixing ½ compost with existing soil and a bit of bark/soil conditioner). Plant the clematis with the crown of the plant 1-2 inches below the edge of the hole, and then fill the top in with mulch (straw and bark are both fine). Watering deeply once a week will help ensure lots of blooms!
Check on which pruning group your clematis is in to know when and how to cut it back for the best blooming results. (Pruning Group 1: prune mid to late spring after flowering has occurred, Pruning Group 2: prune in February and again after the first flush of flowers in early summer, or Pruning Group 3: prune in February.) Don’t panic if you don’t find the time to prune - it just may mean fewer blooms or only one flush for the season.
Below are our 2024 varieties and what makes each one special –
good luck picking just one!
All are sold in one-gallon pots for $18.50.
ASAO
One of the earliest clematis to bloom. Bold, fragrant, bright pink flowers. A good choice for containers or small gardens with trellising. Deadhead after first flush of flowers to encourage rebloom. Climbing 7-9’. (Pruning Group 2)
