Detailed Information

Flower: Flower shape: 4-petals Cluster type: whorled

[photo of flowers] Clusters of 2 to 9 flowers on square stalks at the top of the plant, whorled around upper leaf axils, and at the end of few branching stems arising from upper leaf axils. Flowers are 1/3 to ½ inch long with 4 petals, each have a tubular spur up to 1/5 inch long, extending back past the sepals, becoming broadly oval above the spur and narrowing to a pointed tip. Blooms are observed mostly closed like a short cone, opening only slightly with petals tips curled out. Color is mostly light green or purplish, especially into the spur. The sepals are green, elliptic, adjoined between the spurs, about half the length of the petals above the spur.

Leaves and stem: Leaf attachment: basal Leaf attachment: opposite Leaf type: simple

[photo of leaves] Leaves are ¾ to 1½ inches long, ¼ to ½ inch wide, toothless, hairless, and glossy. Basal leaves are oval to spatula shaped, narrowing to a short stalk; stem leaves are broadly rounded at the base, tapering to a sharp point, strongly 3 or 5 veined, mostly stalkless, and widely spaced on the stem. Stems are hairless, square and unbranched or few branched.

Fruit: Fruit type: capsule/pod

[photo of fruit] Fruit is a conical capsule that protrudes from the opening of the flower like a rhinoceros horn.

Notes:

The flowers on the Spurred Gentian, like many of the gentians, never fully open. Between the subdued flower color and  green of the foliage it is a species easy to pass by in the lush undergrowth of damp woods and bogs. If you manage to notice one, suddenly you see the many around you.

Saw this all over working on the Sturgeon River Trail in the Superior National Forest North of Chisholm.

We found this along the Dr. Roberts trail, not knowing what it was. As you described, by the time we had figured it out, we realized it was all around us.

I found it on the trail in a boggy area. I didn't know what it was, thought it may be related to the aquilegia but was delighted to find it a gentian.

Found a patch of plants growing near the shore in mid-August, on an island in the park.
