Pollen Color Notes

The visual color shown for Willow 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

Willow is listed for spring. The record lists USDA zone 2 - 9; hardiness zones are planning context, not a precise flowering calendar. Approximate bloom months in the supplemental notes: March, April, May.

Its forage type is pollen and nectar, with pollen value marked as high and nectar value marked as high. Willows can be valuable early forage because pollen and nectar may be available before many showy flowers bloom.

Identification Notes

Willows are trees or shrubs with catkins that often bloom early. Compare catkins, wet-site habitat, and early spring timing before using pollen color as an identification clue.

Flower color note: Catkins, often yellowish or greenish depending on species and sex. Flower color and pollen color may differ.
