This time last year we were heading into an awful, hot, drought-ridden summer — one that trounced the tomato plants, sent container plantings wilting if they didn’t get watered twice a day, and left gardeners exhausted and crabby. As we approach the summer solstice on Friday (yes, it’s still spring for a few more days) we’re celebrating a lush spring that’s been filled with cool days and plentiful rain. Many songbirds had a late start nesting and their melodies fill the woods across the road from our garden.
Earlier this spring, a pair of bluebirds began nesting in a box set in our mixed perennial and shrub border, but, sadly, they were chased off by sparrows. I pulled the empty nest, made of dried grasses, from the box in the hopes that they would return. And they did. They’ve rebuilt their nest, and I’ve seen them chase off curious, bullying sparrows.
The hummingbirds have been extremely slow to inhabit the garden this spring, and I was concerned that some might have fallen victim to the lingering spring cold and evening freezes, but I’ve seen a male and a few females flitting about the driveway and several feeders in the past few days.
My greatest surprise was showing my neighbor, photographer Ellen Hodges, a common rue (Ruta graveolens) that was blooming this week when we both spotted two swallowtail butterfly caterpillars that were busy chomping away on the plant. She snapped this photo (below). And today I spotted a black swallowtail sipping nectar from the blossoms as she deposited a few eggs. Black swallowtails and giant swallowtails use common rue as a host plant for their offspring.
I planted the rue for its ability to attract swallowtails, but it also offers healthy silver foliage and butter-yellow flowers. (Watch the sap as it can cause skin irritation.) There are many plants, including trees, shrubs, and perennials, that serve as butterfly host plants — edibles for the larvae and nectar plants for the adults.
