Remontancy of Clematis

Clematis L.

Remontancy in Clematis is the ability of a cultivar to bloom repeatedly during a single growing season, which is primarily characteristic of cultivars in the second pruning group.

In the reference 4 varieties crop Clematis, where this is mentioned in the description.

The ability to bloom repeatedly in Clematis is conditioned by their biological developmental rhythm, which allows for the formation of flowers on previous year's shoots at the beginning of the season and on current year's shoots in the second half. This trait does not have rigid metrological scales and is assessed by experts through recording the periods and abundance of each flowering wave.

In agronomy, the remontancy of Clematis directly determines the pruning strategy, as a violation of the technology can lead to the loss of the second flowering wave. Plants with the potential for repeated flowering require increased phosphorus-potassium nutrition throughout the season to ensure high ornamental quality, although the intensity of the second wave may vary depending on the characteristics of the cultivar.
