I know many people poo-poo butterfly bushes as a plant for pollinators. It's not native, some people say it's invasive, although I've never seen that in any of my garden settings, and it's not a host plant. But as a nectar source for a wide variety of butterflies, it's hard to beat. When I took these photos, in addition to the swallowtails and monarch, there were skippers, sulfers, a buckeye, and some small frittilaries feeding.
Although milkweeds serve as both a host plant and a nectar source, that's fairly uncommon. Many plants are either a source of nectar for adult butterflies or a host plant for the caterpillars. Plants like parsley, dill, fennel and rue are host plants for swallowtail butterfly caterpillars, but don't produce much nectar in their flowers. That's why having a wide variety of plants in your garden is so important.
Here is a native plant, Joe Pye weed, providing a meal for a bumblebee.
With the regular rainfall, there's lots to harvest from the garden. Mints, basils, chamomile, savory, lemon balm and verbena, oregano, calendula and more are all drying on my racks. Take advantage of the good weather and harvest now so you can enjoy the garden's bounty after the growing season ends.
