The wild radish, Raphanus raphanistrum, is common on Skopelos, growing in disturbed ground, fields and roadsides; it may even be found on the upper reaches of the sandy shore.

The four petaled cross-shaped flowers are easily recognisable; most commonly they are pale yellow but white ones also occur. The annual plants grow rapidly in spring; the flowers opening below the new buds, which develop at the growing tip, as the seed pods form behind.  It is  more delicate than its cousin, the rougher black mustard and the two are often found in the same vicinity.

All parts of the plants are edible and the leaves can be used in the savoury pie, hortopita, with other varieties of wild greens: adding a little hot spice.
