Detailed Information

Flower: Flower shape: indistinct Cluster type: raceme Cluster type: spike

[photo of flowers] Flowers are in a densely packed spike-like raceme 1 to 2½ inches long at the top of the stem. Individual flowers are about 3/8 inch across with 4 white petals that drop off soon after blooming, and 4 thick creamy tipped stamens that project out like the points of a star. One plant has a single cluster, though not all plants flower.

Leaves and stem: Leaf attachment: alternate Leaf type: simple

[photo of leaves] Sterile plants have 1 leaf; fertile plants have 2 or occasionally 3 leaves of unequal size, with heart-shaped bases and pointed tips. The largest leaf is up to 3 inches long and 2 inches wide. There are feint stripes and parallel veins along the length of the leaf. Leaves are toothless and hairless. The main stem zig-zags between the alternately attached leaves.

Fruit:

[photo of fruit] Fruit is a green berry about ¼ inch in diameter, mottled with dull pale red that ripens to dark red in late summer.

Notes:

Canada Mayflower is a common woodland spring wildflower, typically found growing in colonies of various sizes. Formerly in the Liliaceae (Lily) family, all Maianthemum species have been reassigned to Ruscaceae (Butcher's Broom).

Our house lot was part of a tree farm - the flowers are in a small colony underneath a group of scotch pine

I have these growing all over in my native vegetative lot. Quite nice little flowers and can definitely replace the over used Lily-of-the Valley.

Surprised to spot some of these in Eagan MN (Dakota County). Usually I see them further north.

I have a small patch of these growing amid sugar maple seedlings, red baneberry, and near a blue cohosh in a vegetative area under mature sugar maples.

These are growing in the pine forests near the Scenic Drive/Highway 61. They are growing near bunchberry plants.
