Detailed Information

Flower: Flower shape: 6-petals Cluster type: raceme

[photo of flowers] A single raceme of 5 to 15 star-shaped flowers on slender stalks at the top of the plant. Flowers are ¼ to 1/3 inch across with 6 white tepals (petals), 6 white stamens with creamy tips that turn reddish with age, and a creamy colored ovary in the center with a 3-parted style protruding at the top.

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

[photo of leaves] 2 to 4 leaves, usually 3, are alternately attached, nearly erect, and sheathing at the base. Leaves are oval to elliptic, 2 to 4¾ inches long, 1 to 1½ inches wide, with pointed tips, tapering towards the base, toothless and hairless, with numerous faint lines on the surface. The main stem is smooth and green to reddish.

Fruit: Fruit type: berry/drupe

Notes:

Three-leaf False Solomon's-seal tends to grow in colonies. Overall the plant is similar to Canada Mayflower (Maianthemum canadense), but the flower cluster on the latter is more compact and is primarily a woodland species. This species also goes by Latin name Smilacina trifolia but the accepted name in Minnesota is Maianthemum trifolium. Formerly in the Liliaceae (Lily) family, all Maianthemum species have been reassigned to Ruscaceae (Butcher's Broom).

Plant has three long green leaves, stem in middle with three blue berries on little stems on top. Have never seen them before, Only noticed them today walking in woods. Never saw any flowers on them.

We are in the process of restoring our small wooded acreage, once badly overrun by buckthorn. It is located in an area of the Rochester Plateau and pre-settlement vegetation was thought to be oak openings and barrens. We've been at it for about five years now and were thrilled to find a small colony of what looks like these plants up in the woods while hunting for morels this morning. We will continue to watch the area as the summer progresses, in order to make a positive identification, but they sure look like it so far - three light green leaves, sort of like Solomon's seals or Lily-of-the-Valley.

The flowers of this plant are fragrant at least at night. I have seen this plant frequently throughout MN over the years during the day but never noticed a fragrance. Tonight while in a large patch of these in a swamp I became very aware of their fragrance which is sweet and filled the air.
