How to attract butterflies to your garden
While just about any flower with nectar can be a treat for butterflies, it is a slightly different story for caterpillar food or 'host' plants. In fact, most butterfly species have just a short list of host plants. Often this is because caterpillars need particular chemicals from that plant to bring out their warning colouration as butterflies.
Some butterflies and caterpillars overwinter, so shelter in the garden, such as thick growths of ivy, is also important.
