Citrus

Citrus are evergreen shrubs or trees prized for their large, juicy fruits. All are extremely decorative plants with glossy, dark green leaves that set off the fragrant white flowers and then the vibrantly colored fruits. Most citrus bear fruit without cross-pollination and require little pruning. Exotic-looking, they are terrific additions to the landscape, patio containers or as houseplants. Wouldn't it be wonderful to pluck your homegrown lemons, limes, oranges or pummelos fresh from the tree?
