Insects and Your Garden: The Vital Partnership of Pollination

While some insects are unwanted indoors, many play essential roles in pollinating plants and dispersing seeds—without them, most plants couldn’t reproduce. Gardeners know this cycle matters, but few fully understand why it occurs or how it benefits both plants and animals.

Rewards for Pollinators

Nectar: A sugary solution prized for taste and energy. Flowers store nectar in nectaries (often in flowers, sometimes leaves). Plants protect nectar from non-pollinators with specialized access. Sugar concentrations have co-evolved to match pollinator needs—e.g., bees require 30–35% sugar for winter honey, so bee-pollinated flowers evolved high-sugar nectar.

Pollen: Eaten by bees, made into protein-rich “bee bread” for larvae. Some plants (peonies, poppies, roses) offer only pollen. Others produce two pollen types: normal reproductive pollen and sterile, tasty pollen to attract pollinators while ensuring reproductive pollen spreads.

Attracting Pollinators

Bright colors attract sight-oriented pollinators; strong scents attract nocturnal, smell-oriented ones. This co-evolutionary partnership is a fascinating study in mutual dependence.
