Variety traits

Clematis double flowering

Clematis L.

Clematis double flowering is an increase in the number of sepals due to the transformation of stamens into staminodes. The trait is cyclical and manifests primarily on the previous year's shoots.

In the reference 59 varieties crop Clematis, where this is mentioned in the description.

In clematis, double flowering is determined by qualitative morphological indicators. Unlike typical single flowers with 6 sepals, double forms can contain up to several dozen sepals, formed as a result of the transformation of stamens into modified petals.

The trait is closely related to the flowering type: for many cultivars, it is characteristic to produce double flowers only on overwintered shoots, whereas current-year shoots may bear semi-double or single flowers. This necessitates following the pruning group 2, as preserving last year's wood is critical for realizing the cultivar's ornamental potential.

Double-flowered cultivars possess biological characteristics that affect propagation: they demonstrate a lower capacity for cutting rooting and require more frequent rejuvenation of mother plants compared to single-flowered counterparts. Agronomically, such cultivars require careful covering and specific maintenance to ensure the preservation of the shoots.
