Nettles are a food plant for the caterpillars of the Comma, Small Tortoiseshell, Red Admiral and Peacock butterflies. If you want to attract butterflies to your garden, and are thinking of including a patch of nettles in your garden, remember that the nettles need to be growing in a warm, sunny spot, so the butterflies will be able to find them.
If you're looking to attract butterflies, bees, and other pollinating insects to your garden, there are lots of flowering plants to choose from. Pictured here outside the Butterfly Dome at the RHS Hampton Court Palace Flower Show 2016 are cornflowers (Centaurea cyanus), Astrantia, and Geraniums. Other good butterfly plants include Buddleja, Knautia macedonica, thyme, and lavender to name but a few.
