Zinnias
Zinnias (Zinnia elegans), natives of Mexico, are a summer gardener’s delight when planted in June. Sow seeds directly in sunny spots with well-draining soil, spacing them about 6–12 inches apart depending on the variety—larger dahlias-style zinnias need more room, while dwarf types can be closer together. They germinate in 5–7 days, and soon thick green foliage produces bright, pompom-like blossoms in pinks, reds, yellows, and purples. Their sturdy stems make them perfect for cutting gardens: I love snipping off a few blooms each morning for fresh vases—such an instant mood lifter!
Zinnias are also pollinator powerhouses. Bumblebees, butterflies (especially swallowtails and fritillaries), and native solitary bees swarm the flat, open centers searching for nectar, while lady beetles patrol for aphids that sneak in on emerging foliage. One tip: watch for powdery mildew, which can appear in late midsummer—plant resistant varieties like ‘Lilliput’ or ‘Benary’s Giant’ and ensure good air circulation by spacing plants adequately. When you deadhead zinnias regularly, they’ll produce new blooms well into September, making them a June planting you’ll thank yourself for when August heat bakes everything else.
