Alphabetical list of plants.

Radishes are an edible root vegetable. They come in a variety of colors, with the most common being red and white. The root of the radish is crisp and has a sharp peppery flavour, with some radish varieties being hotter than others.
Radishes are most commonly used in salads, and can be preserved by pickling them. Radish leaves and seeds are also edible but not as many people eat them as eat the root.
Raspberries are the fruit of a very vigorous deciduous thorny bush related to blackberries, roses and strawberries. Raspberries can spread by sending out roots a long way under the ground that then sprout new plants. Raspberries can take over your backyard if you don't keep them pruned.
Raspberries can be eaten fresh, made into juice, or cooked into pies. Raspberries are very good for you.
Rattan is a type of palm tree that grows like a vine. It grows very fast, and can grow up to a hundred metres long. Rattan is harvested mainly to make cane furniture from.

Red valerian, also called Jupiter's beard, spur valerian or just valerian, is a pretty garden plant grown for its large spikes of pink flowers. It will tolerate drought, frost and highly alkaline soils - it can even grow in the cracks of a limestone wall. The whole plant is edible but is not particularly tasty.
It can be confused with true valerian, which is an unrelated plant with medicinal properties.
Rice is the largest crop grown for food in the world. Most rice is grown in China and India. Rice is a type of grass that grows to about a metre high. Rice needs a lot of water to grow, and in countries like Australia that have a low rainfall people are calling for rice growing to stop.
Rice is usually eaten cooked plain, but can be prepared in a lot of different ways and served with lots of different foods. Rice can even be puffed, a little like popcorn.
