Not to forget the yellow Clematis orientalis, which bloom from July to October, followed by decorative pods in autumn and winter. There is no trace of frost sensitivity here.
Perennial clematis score with their robust winter hardiness
They have a special status within the multi-faceted clematis family. Perennial clematis do not climb, at least they can reach a height of 100 centimeters with a support. They present their lavish blooms in almost any location for complete retreat during the winter. In the following spring they sprout reliably again. The following types and varieties are particularly recommended:
- Clematis integrifolia 'Pastell Blue' with pretty, nodding bell flowers and a flowering period from June to September
- Clematis jouiniana 'Mrs. Robert Brydon' impresses with numerous white flowers from July to October
- Clematis aromatica exudes a bewitching scent from its dark purple flowers
All perennial clematis are not only extremely winter-proof, but have also established themselves as excellent companion to roses.
Tips for wintering
Are there any doubts about which clematis grows in your garden? Then take the following precautions so that the flower beauty comes through the cold season:
- A young or not hardy clematis protect against cold and snow with garden fleece
- Pile up the root area with leaf soil, bark mulch or straw
- Wrap the tendrils on the climbing aid with jute or fleece
If a clematis is considered winter-proof, this property does not apply to a container plant. In this case, moving to frost-free winter quarters should be considered. Alternatively, wrap the planter thickly in bubble wrap and place it on an insulating base made of wood or plastic so that the root ball does not freeze through.
Tips & Tricks
Do not be alarmed if your clematis freezes back to the ground for sunny locations such as Clematis texensis or viorna. At first glance, these summer bloomers appear like a perennial, but they thrive as a woody climbing plant and are winter-proof. If you cut these clematis back to 20 centimeters after flowering or in late winter, they will sprout happily the next year.
