The Canada mayflower (Mainanthemum canadense) is a small flower that is native to the northeast of North America.You may spot it in upland woods and clearings. But don’t say you weren’t warned: Once you see one, you begin to spot mayflower everywhere.
There’s good reason the Canada mayflower is so prolific: It can create carpeted colonies through its network of rhizomes, or extensive system of underground roots. Another well-known plant, bamboo, also makes use of this type of horizontal root system.
Canada mayflower is actually part of the lily family with leaves that appear heart-shaped as they clasp to the zig-zag pattern of the stem.
The Latin name translates to the “when, what and where” of the origins of this plant. Maius meaning “May”, anthemon meaning “flower” and canadense meaning “Canada.” In some circles, it is also called “bead ruby,” in reference to the red, edible fruits that develop in the fall.
True to its name, Canada mayflower first emerges around May. At first, one to three leaves come up from the ground tightly curled, giving it a spikey appearance. Only those plants that have two or more leaves will develop flowers. Larger clusters of the plant may pop up in places where the canopy opens and allows more sunlight to reach the forest floor.
Canada mayflower serves another purpose in the forest ecosystem. It acts as a form of sustenance for many woodland creatures. Slugs and moth larvae eat the leaves in the spring while grouse and small rodents feast on the juicy berries in autumn.
Canada mayflower is a welcome visual in the northwestern New Jersey landscape. If you’re out and about enjoying nature this time of year, keep your eyes peeled for these pretty, flowering plants.
