Design and Handling Notes

Harvest Stage: For cut use, dahlias should be harvested when almost fully open — buds rarely open in the vase.
Hydration: Recut stems at an angle, place in deep water, and allow several hours to rehydrate before use.
Temperature: Store cool (not cold); avoid refrigeration below 7°C, which can damage petals.
Longevity: Dahlias are best for short- to medium-term events (3–5 days); use closer to event time for peak freshness.
Design Role:
- Large decorative forms: focal flowers.
- Ball and pompon forms: structure and rhythm.
- Cactus and collarette types: texture and movement.
Colour Planning: Dahlias shift in tone with maturity and light — coral tones often fade to blush, while dark reds may deepen in cooler light.
Pairing Suggestions:
- With roses and lisianthus for romance.
- With grasses, amaranthus, and seed heads for autumnal naturalism.
- With cosmos and scabiosa for soft, meadow-inspired design.

Whether designing a modern neutral arrangement, a jewel-toned autumn centerpiece, or a painterly editorial piece, dahlias bring dimension, texture, and depth like no other flower.

Mastering their variety, seasonality, and handling transforms them from mere blooms into expressive design tools — a signature of artistry in late-summer and autumn floral work.
