Notes: Wild Radish is a larval host plant of a number of butterflies: Large White, Small White and Green-veined White. It is a significant source of pollen and nectar for a variety of pollinators, especially for honey bees in early spring. Raphanus raphanistrum varies in colour, usually from white to purple but sometimes light orange to yellow, often with colour shading within a single petal. It has been introduced into most parts of the world, and is regarded as a damagingly invasive species in many continents. This species that spreads rapidly is often found growing on roadsides or in other places where the ground has been disturbed.
