Undulatus
/un-dyoo-LAH-tus/🏷️ Taxonomy●● Intermediate
Also known as: undulata, undulatum
A texture and form epithet describing a surface or margin that undulates gently — with shallow, wave-like rises and falls rather than the deeper waves of sinuatus. It may refer to wavy leaf margins, wavy leaf surfaces, or gently rippled petals. Appears as undulatus (masculine), undulata (feminine), or undulatum (neuter).
Etymology
From Latin undulatus, meaning "wavy" or "undulating," from unda (a wave).
Example
“Hosta undulata and Tulipa 'Undulata' both have the gently rippled, wave-surfaced leaves or petals the epithet describes — a visual texture that catches light beautifully and adds movement to a planting.”
