Raphanus sativus Radish (1 Page of 5) The Raphanus sativus plant species is found in A plant of cultivation. the origin of which is obscure. It probably arose through cultivation. It is a member of the Cruciferae family. Common gardeners may know the plant as Radish. Some home gardeners know the variety as R. raphinastrum sativus. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Raphanus sativus Common Name: Radish Family: Cruciferae Author: L. Known Hazards: The Japanese radishes have higher concentrations of glucosinolate, a substance that acts against the thyroid gland. It is probably best to remove the skin[160]. Mature Height: 0.45 Mature Width: 0.2 Habitat: Not known in the wild.
Cultivation Notes: Prefers a rich soil with ample moisture[16, 52]. Dislikes very heavy or acid soils[16, 37]. Some of the Oriental radish cultivars have been selected for growing in clay soils, the swollen part of the root is formed on the soil surface[206]. Plants are susceptible to drought and require irrigation during dry spells in the summer or the root quality will rapidly deteriorate and the plant will go to seed.
Radishes are widely cultivated for their edible roots. There are many named varieties[183] that are able to supply roots all year round. There are numerous types of radish though they can loosely be divided up into 4 main groups:-
The first group are small rooted and fast maturing radishes that are grown primarily for their roots which are used in salads. These are mainly grown for spring, summer and autumn use and can produce a crop within a few weeks of sowing.
Another group does not produce roots of good quality and is cultivated mainly for the edible young seedpods which are harvested in the summer.
A third group contains the Japanese radishes and other winter radishes. These are grown for their larger edible root which is available throughout the winter.
Finally there are the fodder radishes, grown mainly for their leaves and used as a green manure or stock feed though they can also be eaten by people. The roots of these plants soon become fibrous, though they make acceptable eating when young.
Radishes are a good companion plant for lettuces, nasturtiums, peas and chervil, tomatoes and cucumbers[18, 20]. They are said to repel cucumber beetles if planted near cucumber plants and they also repel the vine borers which attack squashes, marrows and courgettes[238]. They grow badly with hyssop[18, 20] and with grape vines[201].
