Tomato plants are vines, largely annual and vulnerable to frost, though sometimes living longer in greenhouses. The flowers are able to self-fertilise.

The cherry tomato is a type of small round tomato believed to be an intermediate genetic admixture between wild currant-type tomatoes and domesticated garden tomatoes. [2] Cherry tomatoes range in size from a thumbtip up to the size of a golf ball , and can range from spherical to slightly oblong in shape.
Heirloom tomato cultivars can be found in a wide variety of colors, shapes, flavors, and sizes. Some heirloom cultivars can be prone to cracking or lack disease resistance. As with most garden plants, cultivars can be acclimated over several gardening seasons to thrive in a geographical location through careful selection and seed saving.
