Are clematis annual or perennial?

Clematis come in several groups based on their pruning needs. All three groups are generally perennial in zones 5-8


However plants can be found perennial to zone 3.


This site lists clematis by zone

Catergory I are not pruned


Cat II early/mid season large flower types that require light pruning only.


Cat III are herbaeous or non climbing as well as large flowered, and autumn blooming small flowered varieties that must be hard pruned.





In cat I are several genus including alpina, armandii, macropetala, and montana. Since these are unpruned and both cirrohosa and armandii are evergreen this is sometimes what is being referred to as the hardier clematis. Many of these plants are zone 3 hardy.





Cat II includes only large flowered cultivars. When most people speak of clematis these are the ones they usually mean because they have such glorious blossoms. The majority are zone 5-8, although there are some perennial to zone 3.





Cat II includes my favorite group the viticellas. These are typical from zone 6-9. These can be pruned right down to keep small or allowed to climb to full height. They can be showy like Clematis 'Purpurea Plena Elegans' and cold hardy to zone 3
