grandiflorum
/gran-dih-FLOR-um/🏷️ Taxonomy● Basic
Also known as: grandiflorus, grandiflora
A floral epithet marking a species whose flowers are notably large, either against its close relatives or against garden plants generally, and the neuter form used where the genus is neuter. Size is judged relative to the genus, not in absolute terms. Appears as grandiflorus (masculine), grandiflora (feminine), or grandiflorum (neuter).
Etymology
From Latin grandis, meaning "large," with flos/floris (flower).
Example
“Trillium grandiflorum (large white trillium) and Epimedium grandiflorum 'Lilafee' (barrenwort) take the neuter ending to agree with their genera.”
