Pollen Color Notes

The visual color shown for Dahlia is grouped broadly with orange and amber pollen tones. It is intended for comparison and identification support, not as a laboratory measurement.

Pollen color is highly variable. Lighting, pollen age, moisture, collection method, cultivar, and local growing conditions can all change how pollen appears. Use this as general visual guidance, not a scientific color standard or guaranteed field match.

Bloom, Zone, and Forage Context

Dahlia is listed for summer to fall. The record lists USDA zone 8 - 10; hardiness zones are planning context, not a precise flowering calendar. Approximate bloom months in the supplemental notes: July, August, September, October.

Its forage type is pollen and nectar, with pollen value marked as low and nectar value marked as low. Single and open-centered cultivars are generally more accessible to bees than densely doubled forms.

Identification Notes

Garden dahlias are tuberous plants with opposite leaves and composite flower heads in many forms; highly doubled cultivars may hide pollen-bearing disk florets.

Flower color note: Many colors, including white, yellow, orange, pink, red, and purple. Flower color and pollen color may differ.
