Calamondin Orange
Citrus × microcarpa
Family Rutaceae
Calamondin Orange is the citrus that never leaves the house — flowering and fruiting at the same time, often all winter, so a sunny sill carries fragrant white blossoms beside ripe orange fruit in midwinter. The fruit puckers lips raw but makes marmalade people fight over.
Compact at three to six feet potted, self-fertile, and generous nearly year-round, it doubles as a Filipino kitchen staple — calamansi — squeezed over everything from noodles to grilled fish. Collectors call it the gateway citrus for a reason. Clear a spot at your brightest window.

Is calamondin orange safe for kids and pets?

One caveat on this one: Skin oils mild pet irritant. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.
When do you harvest calamondin orange?
Small tart orange fruit nearly year-round, holds on the tree beautifully.
How do you propagate calamondin orange?
