KUL-tih-var/ˈkʌltɪvɑːr/
A plant variety produced or maintained through cultivation.
These two rose cultivars display different flower colors and shapes.

Etymology
Cultivar compresses “cultivated variety” into a name for a plant variety produced through cultivation. The formation puts human growing and tending at the center of the distinction.
In context
also known as Japanese bunching onions. Basically, they have this really long stalk, and they don't produce the bulb. So, the true scallion doesn't, actually, produce the bulb. It's a cultivar of the onion species
