Variety traits

Verbena flowering duration and abundance

Verbena L.

Verbena flowering characteristics are assessed by duration in days (from 60 to 120 days) and a multi-point abundance scale, which depends on the cultivar's bushiness and lighting conditions.

In the reference 21 varieties crop Vervain, where this is mentioned in the description.

The duration of verbena flowering under introduction trial conditions varies from 60 to 120 days. Flowering abundance is determined by expert evaluation using a multi-point scale and is closely correlated with the total number of flowers and the number of flowering points on the plant.

Flowering indicators of verbena are significantly affected by the light regime. As the plant is a facultative long-day species, increasing the photoperiod to 16 hours accelerates development and improves flowering quality, whereas a lack of light leads to elongated bushes and reduced abundance.

To maintain high ornamental value and abundance throughout the season, agrotechnical practices are applied, such as the regular removal of faded inflorescences to stimulate new flower stalks and the pinching of the bush, which promotes increased branching.
