Variety traits

Drought tolerance of Hibiscus syriacus

Hibiscus syriacus L.

An adaptive trait of Hibiscus syriacus, assessed on a five-point scale to determine the potential of cultivars in southern regions.

In the reference 6 varieties crop Rose of Sharon, where this is mentioned in the description.

A five-point scale is used to evaluate the drought tolerance of Hibiscus syriacus, where scores of 4–5 are considered high. Cultivars with these ratings exhibit the greatest adaptability and are capable of maintaining their ornamental appeal and productivity during the summer period, which is critical for sustaining continuous flowering.

In scientific research, anatomical, morphological, and physiological indicators are used to analyze tolerance. With an insufficient level of drought tolerance (below 4 points), plants experience reduced flowering intensity, slowed growth, suppressed photosynthetic activity, and leaf scorch.
