Tomatoes are often considered an outside plant, but there are several varieties that grow well indoors. Smaller grape and cherry varieties are the most common type of indoor tomato plants, but there are also a handful of larger tomatoes that do well inside. Regardless of their location, all tomato plants require moist soil and adequate sun exposure. Indoor plants should be placed in direct sunlight and watered frequently.
Pixie tomatoes (Lycopersicon esculentum) grow on a dwarf bush that yields tennis ball-sized fruit that typically matures in about 52 days. The pixie tomato bush grows well indoors and reaches a height of approximately 2 feet. It prefers warm conditions with adequate sun exposure, as well as moist, well-drained soil.
The patio tomato (Lycopersicon esculentum) is a cherry tomato that typically reaches maturity in about 50 to 70 days and produces a 4-ounce, or slightly larger, fruit. This variety grows easily in a small pot or window container. The patio tomato prefers temperatures above 75 degrees Fahrenheit, as well as plenty of sun. Frequent watering is necessary for moist, well-drained soil conditions.
The better boy (Solanum lycopersicum) variety is an improved version of the big boy tomato. A larger-sized tomato, better boy grows well both outside and indoors in a container. The better boy tomato typically matures in about 72 days, producing a firm and round 12-ounce fruit. Better boy requires moist--but not wet--soil and at least six hours of sunlight per day. This variety of tomato is very popular both for its ease of growth and flavorful taste.
The husky gold (Lycopersicon esculentum) is a hybrid, slightly larger-sized golden tomato. A popular choice for indoor containers, fruit reaches maturity in approximately 70 days, yielding a 7-ounce globe-shaped tomato. The husky gold requires consistently moist soil and should be placed in direct sunlight. Husky gold grows in a compact manner and yields sweet-tasting fruit.
