Attracting Pollinators

Pollinator populations have declined significantly in recent years, mainly due to habitat loss. Homeowners can help by creating pollinator-friendly gardens. Knowing plant traits such as flower color, shape and scent will guide you to which plants to choose for pollinators.

Hummingbirds are attracted to flowers of vivid shades of red, yellow, and purple with a tubular shape that they can access with their long narrow beaks.

Bees prefer purple, blue, orange, or yellow flowers with short tubes or no tubes which they can easily access.

Butterflies are drawn to white, pink, red, yellow, or purple flowers with a place they can perch while sipping on nectar.
