The North American species of Aster (reclassified in the 1990s to other genera, but still commonly known as asters) are flowering perennial herbs usually bearing striking blue, mauve, pink, or white flowers. These lovely plants share an important symbiosis with bumble bees: the bees are one of the asters’ key pollinators and for many bumble bees, asters are a major food source. Asters are also easy to grow and thus a great choice for Canadian gardeners.Bumble bees are among the most resilient types of bees and prefer temperate climates. Because they are generalists, gathering nectar and pollen from a wide variety of flowers (up to 20 flowers per minute), it is somewhat easier for them to survive environmental changes. Nevertheless, like many bees, they are threatened by factors such as habitat loss, parasites, and pathogens. Luckily, anyone can help to support and attract bumble and other bee populations by planting a variety of native flowering plants.
