u/pig_killer

A noun, from the French. ("o-rahnzh-ree" or "aw-rinzh-uh-ree" or "or-inj-uh-ree")

A dedicated winter home for tubbed or potted non-hardy citrus. Orangeries are typically built in the Northern Hemisphere.

Also seen as "orangery," which has a somewhat different flavor in text, but the same meaning-- a building for citrus trees.

Oranges are botanically referred to as a hesperidian berry, and the fruit, orange itself is a "hesperidium." . . . From this arises a new question-- would an ancient Roman orangerie perhaps be a hesperidiumarium?
