Orange Tree (Calamondin)

This perennial shrub is actually a cross between a kumquat and a tangerine. Woody stems of this dwarf citrus tree are densely covered with oval, glossy green leaves that have a citrusy aroma.

You can expect an abundance of flowers and fruits, beginning in its second year. Fragrant, white, star-shaped flowers will appear at the tips of branches in summer, followed by 1-2 in (2.5-5 cm) fruits. Ripening slowly, the fruits change from deep green to bright orange. You'll usually see flowers and fruits on the tree at the same time, making calamondin tree a fresh, colorful accent for a sunny room.

There is no hurry to pick calamondins. They're long-lasting, so you can enjoy them for months on the tree. These oranges are tart, to say the least.
