Drought tolerance — Buddleja davidii

Buddleja davidii Franch.

The drought tolerance of Buddleja davidii is defined as the qualitative adaptive ability of the plant to maintain viability after the root system has formed, evaluated by the degree of leaf turgor.

In the reference 6 varieties crop Butterfly bush, where this is mentioned in the description.

For Buddleja davidii, there are no quantitative physiological indicators of drought tolerance. The criterion for water stress is the drooping of leaves during the daytime with subsequent recovery of turgor in the evening. If the loss of turgor persists into the morning hours, this indicates a critical moisture deficit requiring irrigation.

The plant acquires drought tolerance only after the rooting period is complete. In the first year after planting, regular watering is required; subsequently, the frequency of irrigation can be reduced, carrying it out only during prolonged periods without precipitation. The depth of the root system development directly correlates with the crop's endurance under conditions of limited moisture.
