Pleniflorus
/plee-nih-FLOH-rus/🏷️ Taxonomy●● Intermediate
Also known as: pleniflora, pleniflorum
A floral epithet indicating the flower has extra petals — either fully double (in which the stamens and pistils are wholly replaced by petals) or semi-double. Double-flowered forms are highly prized in cultivation for their voluptuous, petal-packed blooms. Appears as pleniflorus (masculine), pleniflora (feminine), or pleniflorum (neuter).
Etymology
From Latin plenus (full, complete) + flos/floris (flower), meaning "full-flowered."
Example
“Prunus avium 'Plena' (double gean) and Rosa 'Pleniflora' selections — with their many-petalled flowers — exemplify the extra-petalled abundance this epithet promises, often at the cost of the fruit or seed production of the single-flowered form.”
