Variety traits

Vigor of verbena

Verbena L.

A qualitative characteristic reflecting the plant's development energy, rate of shoot elongation, branching intensity, and ability to fill the allotted volume.

In the reference 48 varieties crop Vervain, where this is mentioned in the description.

For verbena, vigor is determined through a set of parameters, including the rate of internode elongation, foliage density, and the ability to recover after pinching. Evaluation is conducted visually using scales that categorize varieties into compact, medium-growing, and vigorous.

High vigor is characteristic of trailing and ground-cover forms, which require increased spacing and control of shoot stretching. Moderate vigor is typical of pot series; such plants require careful agrotechnical management to prevent fungal diseases.

This trait serves as a technological guideline for planning planting schemes and nutrient strategies. Excessive development of vegetative mass, stimulated by nitrogen fertilizers, leads to a loss of ornamental value; therefore, temperature regimes and growth regulators are used to manage the habit.
