Lollo Bionda (green) and Lollo Rosso (red) are terms used referring to the fancy lettuce with tight curly leaves, otherwise known as coral lettuce. The leaves are produced loosely in a whole head, are tender in taste, with a slight bitterness.
These very decorative lettuce types add a punch of colour, texture and volume to salads. The curled leaves also have a practical function as they increase the surface area enabling salad dressings to be caught up in the leaf and not to the bottom of your salad bowl.
The oak leaf lettuce is named because of the shape of the leaves, resembling an oak tree. Normally green but also available in red varieties. They have a sweet, tender taste to them, with somewhat of a velvety texture.
Often grown as a whole head, sometimes in hydroponics where the roots are still attached and is also the cut leaves come in pre-packaged salad mixes. This decorative lettuce is often mixed with other lettuce to create contrast, various textures and colours in salads.
