I try to provide both host and nectar plants in my garden. Some of the nectar plants are pentas and lantana. Host plants include my passion vine for zebra longwings and gulf fritilaries, milkweed for monarchs and queens and parsley and dill for swallowtails

The passion vines are quite prolific and the flowers are beautiful. They require little care. The passion vine grows very well on a trellis. However, when the zebras and fritillaries move in, they can really make a mess of the leaves, but the vine is prolific and grows very fast, so there'll almost always be enough leaves for the caterpillars.
Pentas, especially the red ones seem to be about the most popular nectar plant in the garden.
