Summer in the Portland metro is flower season: long, warm, mostly dry days and a wide range of blooms all at once. Here is your guide to summer flowers in Tualatin, Sherwood & the South Metro for 2027.

🌻 What’s in Season: June–August

June: Peonies (early June, last chance), roses (peak season begins), sunflowers, dahlias (early varieties), stock, delphinium, sweet peas, lisianthus
July: Roses (full peak), sunflowers, dahlias (main season), zinnias, gladiolus, hydrangeas, lilies, lavender
August: Dahlias (peak), sunflowers, zinnias, rudbeckia, celosia, late-season roses, asters

Long summer days tend to produce flowers with vivid color and strong stems. This is a typical calendar, and what is available in any week varies, so the stems in a given arrangement can differ from the list above.

📅 Summer Occasion Calendar

Late May–mid June: Graduation season — congratulations bouquets, plants, and gifts (each school sets its own date)
May 31 (Monday): Memorial Day — cemetery tributes and patriotic arrangements
June 20 (Sunday): Father’s Day — arrangements, plants, gift baskets
July 4 (Sunday): Independence Day (observed Monday, July 5) — red, white, and blue arrangements, BBQ centerpieces, hostess flowers
June–September: Wedding season — flowers for couples, hosts, and the people who love them
All summer: Birthdays, congratulations, get well, housewarming, thank you

🌡️ Summer Flower Care

Keep arrangements cool. Summer arrangements last longest in an air-conditioned room, away from direct sunlight and windows that heat up in the afternoon.
Change the water daily when temperatures climb past 80°F. Warm water grows bacteria faster, and fresh, cool water helps flowers last longer.
Plan the delivery. If the recipient will not be home, say so in the delivery notes and name a shaded porch or covered spot.

🎉 Summer Hosting & Outdoor Flowers

BBQs, patio dinners, pool parties, outdoor graduations — summer hosting calls for flowers that can handle warmth and look great outdoors:

Sunflowers, dahlias, and zinnias are among the most heat-tolerant cut flowers. They tend to hold up at outdoor events better than roses or hydrangeas.
Low, compact centerpieces work best for outdoor dining tables — wind will not knock them over and they do not block conversation.
Potted plants as table decor — succulents, herbs, or small blooming plants that guests can take home as favors.
