Designing a Colorful Mid-Summer Garden: Perennials, Annuals, and Hydrangeas

Mid-Summer Peak

Perennial border at its best: sun-loving flowers blooming, early bloomers lingering, late bloomers emerging. Annuals peak. Full shrubs backdrop. Late perennials fill gaps.

Focus: Perennials and Annuals

Most flowering trees/shrubs done. Autumn color months away. Spring bloomers fading, late bloomers starting.

Sun-Loving, Taller Plants

Unlike early shade/woodland border, mid-summer border centers on taller, sun-loving varieties—many from mid-west prairies.

Star Performers

• Daisies: Abundant, varied colors/sizes. Deadhead for new flush.
• Hollyhock & Delphinium: Old-fashioned, tall, full-sun, cottage garden classics.
• Daylily: Classic, abundant short-lived blooms.
• Lady's Mantle: Yellow flowers, great edging.
• Geranium: Low-growing, front of border.

Hydrangeas: Indispensable

Versatile shrubs for summer color/texture. No garden complete without them.

• Preferences: Part shade, rich organic soil, morning sun/afternoon shade. Avoid morning shade/afternoon sun (heat stress).
• Water heavily, especially young plants. Mulch well.
• Fertilize spring and late summer.
• Varieties: Lacecap (ring of flowers), Nikko Blue (pom-pom), Oak Leaf (oak-like leaves, white-to-pink blooms), Climbing (white vine, aerial roots).

Plan Ahead

So many choices—prepare a list before greenhouse visit. You'll still discover surprises, but a list keeps you focused.
