Pollen Color Notes

The visual color shown for Onion 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

Onion is listed for summer and USDA zone 5 - 10. Approximate bloom months: June, July, August. USDA hardiness zones are planning context, not a precise flowering calendar.

Its forage type is pollen and nectar, with pollen value marked as low and nectar value marked as medium. Onion flowers can provide nectar and pollen in seed-production or bolted crop contexts, but value varies by cultivar and management.

No named honey type listed is the honey-type note currently attached to this plant record. Use the values here as a field-guide reference rather than a local bloom guarantee.

Identification Notes

Onions have hollow leaves and rounded umbels of small flowers when allowed to bloom. Use the allium scent, bulb crop context, and umbel structure with pollen color.

Flower color note: White to pale purple. Flower color and pollen color may differ.
