Wild thyme, common clover, sainfoin, buttercup, willow-herb, wild sage, five-finger and lilies are only a sample of the many flowers that colour the mountain meadows and attract the bees. There are also flowers that repel bees, reserving their nectar to other pollinating insects who skilfully penetrate inside the flowers' deep and unusually shaped corollas. In woods where lime trees, wild cherries, mountain ash, beech and fir-trees grow, great quantities of nectar and honeydew lie hidden. In clearings raspberry, rhododendron, blueberries and heather offer nectar-filled flowers that the bees have no trouble collecting.
