Bee Happy Plants managing director Sarah Holdsworth encouraged people to buy bee-friendly plants to boost dwindling bee populations. She said varieties such as Melittis melissophyllum (honey-scented balm), Vicia cracca and Geranium pratense (meadow crane's-bill), which have become a scarce sight in the countryside, were all bee-friendly choices.
Holdsworth added: "Without bees there would be no natural fruit or plants. Imagine a world where fruit must be hand-pollinated with a paintbrush. A bag of apples could cost £100."
She blamed neonicotinoids, a class of insecticides that acts on the central nervous system of insects, for honey-bee colony collapse. Although there has been no scientific proof of damage to the bee population from neonicotinoids, some countries have already banned the use of certain variations.
No bee-friendly plants were for sale because of Kew's disease prevention rules.
