Use large splashes of color and select single rather than double flowers. The nectar of single flowers is more accessible and easier for butterflies to extract than the nectar of double flowers which have more petals per flower. Large splashes of color will attract butterflies. Groups of flowers are easier for butterflies to locate than isolated plants. Include caterpillar host plants in the garden design.
Host plants provide food for caterpillars and lure female butterflies into the garden to lay eggs.
Provide damp areas or shallow puddles in the garden . Butterflies cannot drink from open water, but prefer damp areas and shallow puddles. Male butterflies will congregate at puddles. Place flat stones in the garden. Butterflies often perch on stones, bare soil or vegetation, spread their wings and bask in the sun.
