Summer Flowers: Sunflowers, Dahlias & Heat-Wise Care
Summer is the season of sunflowers, dahlias, lavender, garden roses and many wilder textures. In the Northern Hemisphere that is roughly June–August; in Australia, December–February. Heat is the practical issue: the same flower that lasts a week in a cool room may fade in two days beside a sunny window.
Northern Hemisphere
- Early summer: garden roses, peonies at the tail in cooler climates, hydrangeas, lisianthus.
- High summer: sunflowers, lavender, zinnias, cosmos, gladiolus.
- Late summer: dahlias begin their long show into autumn.
Australia and the Southern Hemisphere
- Australian summer is December–February. Local sunflowers and dahlias follow that heat.
- Indoor air-conditioning in the UAE and hot US cities can help vase life if the cold chain was respected before delivery.
Bouquet ideas
- Sunflowers for an informal birthday.
- Dahlias and garden roses for a late-summer wedding.
- Hydrangea-heavy designs when you need volume.
Care in this season
- Use more water than you think and recut stems on arrival.
- Keep arrangements out of direct sun and away from fruit bowls.
- Hydrangeas and sunflowers are especially thirsty in heat.
Availability
- Field flowers are plentiful in the local summer.
- Imported peonies or ranunculus in high summer are off-season luxuries in the north.
