Seen sipping nectar from the ubiquitous agapanthus, the butterfly does not require exotic plants to to be happy in the home garden.
In nature: swallowtails surf air streams, coursing from ridge lines into riparian canyons. Happiness for the butterfly grows on trees. Literally. Suburban landscapes offering munchies for the caterpillars - birch, citrus, sycamore and willows-green leaves are tasty temptation for this youthful stage of life. Having found abundant food, they will cocoon. Let them rest to emerge to a nectar-filled floral banquet; a bit of water to hydrate-they will consider your garden their haven.
