The fragrant yellow-flowered shrub of Mediterranean coasts; nectarless but rich in pollen, a good early-summer pollen source in maquis.
Spanish broom is a shrub with green, almost leafless-looking stems, very common in maquis, on road embankments and in abandoned fields along the Mediterranean and Aegean coasts. Its flowers contain no nectar; when a bee lands on the flower, the wing petals open and pollen is thrown onto the bee's underside. Thanks to this mechanism honey bees collect plenty of pollen in a short time.
From May to July, in the coastal belt, it bears strongly scented yellow flowers for about 6-8 weeks. Part of the flowering coincides with the start of the summer drought.
As it produces no nectar, it makes no direct contribution to honey production; but in coastal apiaries it can supply a large share of the early-summer pollen intake.
It is a good plant for erosion control and road embankments. The plant contains cytisine and is poisonous to animals; no harm is known for bees or pollen. It is invasive in California and Australia, while in Turkey it is a native species.
