White-flowered rocket carpeting western Mediterranean vineyards and orchards in winter and spring; ample nectar and pollen in a lean season.
White wall-rocket is an annual herb that forms dense carpets in vineyards, citrus groves and orchards and on ploughed fields in eastern Spain, southern France, Italy and North Africa. Its white, purple-veined, four-petalled flowers offer easily reached nectar and plenty of pollen. In these regions it is regarded as one of the most important food sources for bee colonies in winter and early spring, when there is very little else.
Where winters are mild it starts flowering after the autumn rains and continues until May; the peak is February–April.
It goes into mixed winter and spring honeys; its pollen contribution is decisive for early brood rearing. It is not known as a common monofloral honey.
It does not grow wild in Turkey. Where it occurs, early tillage between the rows or herbicides wipe out this winter source; it pays for beekeepers to agree with growers on late tillage.
