About

The tomato (US: , UK: ; Solanum lycopersicum) is a plant whose fruit is an edible berry that is eaten as a vegetable. The tomato is a member of the nightshade family that includes tobacco, potato, and chili peppers. It originated from western South America, and may have been domesticated there, in Mexico, or in Central America. The Spanish introduced tomatoes to Eurasia in the Columbian exchange in the 16th century.

Tomato plants are vines, largely annual, and vulnerable to frost, though sometimes living longer in greenhouses. The flowers can self-fertilize. Modern varieties have been bred to ripen uniformly red, in a process that has impaired the fruit's sweetness and flavor. There are thousands of cultivars, varying in size, color, shape, and flavor. Tomatoes are attacked by many insect pests and nematodes and are subject to diseases caused by viruses, mildew, and blight fungi.

How to grow it

The tomato is grown worldwide for its edible fruits, with thousands of cultivars.
