The trait of doubleness in Freesia is evaluated as a qualitative characteristic of the flower during Distinctness, Uniformity, and Stability (DUS) testing. The grading scale includes three states: single flowers with a standard number of petals, semi-double, and double, for which a quantitative threshold of nine or more perianth segments has been established.

In agronomic practice, it is important to distinguish varietal doubleness as a trait of flower structure from pathological viral changes characteristic of other plant species.
