Spring brings a quiet renewal of life after a long winter. As the snow melts in April and before the trees leaf out, the forest floor comes alive with the first wildflowers.

These are known as spring ephemerals. They bloom, are pollinated, set seed, and go dormant within a short window, before the forest canopy fills in and limits the light reaching the ground.

Their survival strategies are as fascinating as their beauty. Many ephemeral seeds are dispersed by ants, which collect them for their protein-rich coating and later discard them in their nest compost, a nutrient-rich environment that provides an ideal place to grow.

These early blooms also play a vital role in supporting pollinators. Bumblebees, mason bees, mining bees, hoverflies, and bee flies are among the first insects to emerge, relying on these flowers for nectar and pollen. Butterflies such as mourning cloaks, which overwinter as adults, also depend on these early food sources.

Some trees, including red and silver maple, flower at this time as well, providing an important early source of nectar.

By May, familiar favourites like trilliums are in bloom. Around the same time, wild leeks, stinging nettles, dandelion greens, and morel mushrooms begin to appear.



You can spot many of these species at Marsh’s Falls Nature Reserve in early spring. Protecting forests like these helps ensure that spring ephemerals and the pollinators they support continue to thrive across the Lake of Bays region.
