Abundance and duration of flowering — Buddleja davidii

Buddleja davidii Franch.

Abundance and duration of flowering are key quality indicators for Buddleja davidii cultivars, assessed on a scale from 1 to 9 points and by calendar dates.

In the reference 11 varieties crop Butterfly bush, where this is mentioned in the description.

The assessment of flowering abundance is based on the percentage of the crown covered by inflorescences, where a low rating is considered up to 25% of the area, medium is about 50%, and high is up to 100% coverage. The flowering duration of Buddleja davidii typically ranges from 30 to 45 days, depending on varietal characteristics and growing conditions.

Since Buddleja davidii flowers on current-year shoots, mandatory annual early pruning is necessary to maintain high abundance. Removing faded inflorescences stimulates the formation of new flowers, preventing seed set and extending the plant's decorative period.
