Fun Facts About Dahlia

While dahlias don’t produce edible fruit, they’re loved by pollinators and gardeners alike for their vibrant, show-stopping blooms. Their color spectrum ranges from deep burgundy and coral to soft peach and pure white—making them a visual favorite in summer gardens.

These flowers thrive in warm weather and begin blooming in mid to late summer, lasting all the way into early fall. They’re especially important in July and August when other nectar sources start to fade.

Dahlias are native to Central America and were cultivated by the Aztecs, not just for their beauty but also for their tubers, which were once used for food and medicine.

Here’s a fun detail you might not know: dahlias are considered a symbol of creativity, resilience, and grace under pressure—making them as meaningful as they are beautiful.

Planting Requirements For Dahlia

Light: Dahlias need full sun—at least 6 to 8 hours of direct sunlight each day.

Soil: They thrive in rich, well-draining soil. Add compost or aged manure to boost nutrients and drainage.

Spacing: Space dahlias 18" to 24" apart to give the plants room to grow and allow for airflow.

Planting Time: Wait until the danger of frost has passed (late spring). Dahlias begin blooming in July, making them a summer star in your garden.

Zones: 8 – 10 (In Zones 3–7, tubers should be dug up and stored indoors after first frost.)

Time of Bloom: Mid to late summer through early fall. In most areas, July is the kickoff for their prime blooming season.
