Vigor — Verbena × hybrida

Glandularia x hybrida (hort. ex Groenl. & Rümpler) G. L. Nesom & Pruski

This is a quality indicator of development rate, branching intensity, and the speed of vegetative mass formation in the plant. This trait determines the choice of planting scheme and the functional use of the variety in landscape design.

In the reference 9 varieties crop Common Garden Verbena, where this is mentioned in the description.

When evaluating Verbena × hybrida, vigor refers to the plant's ability to quickly occupy the allotted space. The parameter is determined visually or by measuring the dry mass of shoots in comparison with control samples, taking into account stem length and branching density under specific growing conditions.

High vigor dictates the need for an increased feeding area and often requires regular corrective pruning to maintain aesthetic appeal and stimulate flowering. Compact forms with low vigor, conversely, are preferred for dense plantings and container gardening.

There are no unified quantitative standards for this trait; therefore, in catalogs, vigor is indicated relative to other varieties within the same series. Descriptive categories such as 'compact', 'vigorous', or 'trailing' serve as the primary guideline for agronomists when planning plantings.
