What makes lavender so attractive to bees?

I recently visited RHS Wisley and one of their features is a mount covered in lavender. Beautiful in its own right it harboured another beauty namely the thousands of bees that were foraging on its flowers. I know lavender is a good plant for bees but why is it so attractive. ​

Lavender is excellent for bees for several reasons. It produces a high quantity of nectar, which is the primary energy source for bees. Lavender flowers over a long period, typically from late spring to early autumn, providing forage when other flowers may have stopped blooming, offering a reliable food source. Studies show lavender is one of the most nectar-productive garden plants in the UK. It often ranks high in RHS trials for pollinator value. Lavender flowers have a tubular shape but are still relatively easy for bees to access. Bumblebees, honeybees, and solitary bees all thrive on lavender. The aromatic oils in lavender give off a strong, sweet fragrance that is especially attractive to bees. This helps them locate the flowers even from a distance.

Lavender loves the sun, and so do bees. Lavender flowers are often in open, sunny locations, making them easy for bees to find and access. Furthermore, bees have trichromatic vision, like humans, but their colour receptors are tuned to: ultraviolet (UV), blue and green. Lavender appears very bright to a bee they see a strong combination of blue and ultraviolet, which stands out clearly against green foliage. Lavender flowers often have UV patterns (called nectar guides) on their petals that direct bees to the nectar — like landing lights on a runway. Given all these factors its not surprising that lavender bushes are usually covered in bees.
