Red leaf lettuces are a group of lettuce cultivars with red leaves. Red leaf lettuce cultivars include “Lollo Rossa”, “New Red Fire Lettuce”, “Red Sails Lettuce”, “Redina Lettuce”, “Galactic Lettuce”, and the “Benito Lettuce”.

The zucchini or courgette is a summer squash, of Mesoamerican origin, which can reach nearly 1 metre in length, but is usually harvested when still immature at about 15 to 25 cm. A zucchini is a thin-skinned cultivar of what in Britain and Ireland is referred to as a marrow.

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. 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.

A cherry is the fruit of many plants of the genus Prunus, and is a fleshy drupe. Commercial cherries are obtained from cultivars of several species, such as the sweet Prunus avium and the sour Prunus cerasus.

Romaine or cos lettuce is a variety of lettuce that grows in a tall head of sturdy dark green leaves with firm ribs down their centers. Unlike most lettuces, it is tolerant of heat. In North America, romaine is sold as whole heads or as “hearts” that have had the outer leaves removed and are often packaged together.
