Double-flowering in Hibiscus syriacus

Hibiscus syriacus L.

Double-flowering in Hibiscus syriacus is an ornamental trait defined by the number of petals and petaloids, which is evaluated on a five-point scale for cultivar assessment.

In the reference 16 varieties crop Rose of Sharon, where this is mentioned in the description.

A five-point scale is used to evaluate the degree of double-flowering in Hibiscus syriacus blossoms. A score of 1 indicates the presence of individual petaloids in the center, 2 indicates the presence of two rows of petals, and 3 indicates the formation of anemone-type flowers. Scores of 4–5 are assigned to cultivars with pronounced double-flowering, characterized by a uniform filling of the flower with numerous petals and petaloids.

Double-flowering forms of hibiscus may possess 10–30 or more petal-like structures, which visually makes them resemble peony or camellia flowers. This trait significantly affects the ornamental qualities of landscape compositions, while cultivars with varying degrees of double-flowering show different capacities for forming seed capsules.
