A well designed and maintained garden is a joy but what make a garden complete is to have it full of bird song and the fluttering of butterflies.
Shrubs are used to add structure to a garden and can provide interest all year round. The shrub most loved by butterflies is Buddleia but they also like Choisya, Ceanothus, Ceratostigma, Hebe and Lavender. For acid soil try Hydrangea.
In most parts of the country the butterfly season runs from March to November.
