Raphanus raphanistrum ssp maritimus Sea Radish C DD N
This is one of those plants which can be a small straggling thing with a few flowers to the huge plant in the LHS photo taken in North Wales. Yellow crucifers can be difficult to identify but Raphanus raphanistrum has very characteristic fruits shown in the RHS photo. This is the commonest of the sub species and large perennial plants like the one shown are not unusual.
Raphanus raphanistrum ssp maritimus is very much a coastal plant, rarely being found growing inland. It is common on the western coasts of England and on Welsh coasts but is uncommon in the east. It can be found on the south western Scottish coasts but not in the north or the east. In Ireland it is common on eastern and southern coasts and apart from a patch near County Clare, is less common in the west.
