What is the best way to attract butterflies into my garden?
There is a whole range of suitable plants that will certainly attract butterflies (and moths) of certain species, but what they really like are places that have been left untended. Many modern species of plants are totally unsuitable for butterflies because they either do not provide the nectar or because it is there but the butterflies can’t reach it. Some plants they find unattractive, perhaps because they are the wrong colours. For an example, the cultivated buddleias in my garden get a fraction of the butterflies on them compared with one growing wild just a few hundred yards away. The Royal Horticultural Society publishes a booklet on some of the plants that you can grow, which you may find a help.
