The short version
Tomatoes are one of the most popular crops to grow. You can start them from seed indoors or buy young plants, then grow them outdoors or in a greenhouse, in pots or in the ground. RHS: How to grow tomatoes Garden Organic says there are hundreds of varieties, and calls tomatoes a great crop for someone new to growing. Garden Organic: Tomatoes growing guide
Cordon (indeterminate) tomatoes are vigorous, very tall plants that need tall supports. Bush (determinate) tomatoes are naturally more compact, great for smaller spaces. RHS: How to grow tomatoes Small-fruited varieties tend to be the easiest to grow, the fastest to fruit and the most prolific. RHS: How to grow tomatoes
Tomatoes grow particularly well in a greenhouse, usually giving an earlier and larger crop. Outdoors, these tender plants need a warm, sunny, sheltered site. RHS: How to grow tomatoes University of Minnesota Extension calls tomatoes the most popular homegrown vegetable. They need a long, frost-free season and full sun.

The wild tomato came from the Andes of South America, probably mainly Peru and Ecuador. Encyclopaedia Britannica: tomato The Spanish brought the tomato to Europe in the early 16th century. The Spanish and Italians seem to have been the first Europeans to eat it. Encyclopaedia Britannica: tomato
