Detailed Information

Flower: Flower shape: irregular

[photo of flowers] One to rarely two flowers, the inflated lower petal (the slipper) is  ¾ to 1¼ inches long, glossy yellow, with purple splotches lining pouch opening and faint purple veination on lower pouch. Bright yellow flower column, splashed with purple, broadens into a flat oval lip, appressed tightly into pouch opening. Lateral petals are narrow, up to 2 inches long, typically spirally twisted, dark purple/brown but can be lighter, flecked with greenish striping. Sepals are similar in color, 2 are fused behind the lip; upper sepal is broader and is erect above the lip. A single leaf-like, sparsely hairy floral bract stands erect at the top of the stem, behind the ovary.

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

[photo of leaves] 2 to 5 leaves, oval to elliptical, 2½ to 6½ inches long with distinct parallel veins are alternately attached and sheathe the stem. Several scale-like leaves sheathe the lower stem. 10 or more stems may emerge from a single root.

Fruit: Fruit type: capsule/pod

Fruit is an oblong-elliptic capsule containing numerous tiny seeds.

Notes:

From frequent clumped masses in sunny damp ditches along Hwy 59 in Red Lake County, this dainty ballerina like flower migrates deep into coniferous bogs in the Cass Lake area. More adaptable than most native orchids it is increasingly cultivated and available for purchase. There are 3 accepted varieties of Yellow Lady's-slipper, 2 of which are found in Minnesota. The most noticeable difference between var. makasin and var. pubescens (Large Yellow Lady's-slipper) is the flower size; the latter flowers are about twice the size and is overall hairier, the former has flowers about the same size as C. candidum (Small White Lady's-slipper). Also, var. pubescens sepals tend to be more yellowish-green and var. makasin more dark maroon.

Where C. candidum and C. parviflorum (either or both vars) are in close proximity to each other, such as the edge where prairie meets forest, hybrids are likely to occur; the hybrid between C. candidum and C. parviflorum var. makasin is known as C. ×andrewsii. According to Welby Smith's book “Native Orchids of Minnesota”, the hybrids can be baffling, most with intermediate characteristics in flower size and color, but some with different traits of each parent. In each case, the flower color may be white, creamy or yellow. It also mentions a study in Iowa showed hybridization was more common than previously thought, the hybrids cross-breeding between themselves and their parents, known as a hybrid swarm.

Saw a small group of these yesterday. I am not sure if they are the larger or smaller of the yellow lady slippers. I was so excited to see these strange looking flowers!!

There are several clumps of these on a wooded ridge above the Le Sueur River in Blue Earth County. It is a spot just south of Mankato, a 15 or 20 minute walk down river from Red Jacket Park.

Saw two of these in Whitewater State Park on May 30, 2015. One was past its prime. They were located on the trail between Chimney Rock and Inspiration Point.

I was checking the progress of some showy lady slippers that I discovered at a nearby public access and lo! and behold! There were two clumps of small yellow lady slippers in the grass and such tiny flowers that I almost overlooked them. I was shocked at how small they are, I have regular yellow lady slippers on my property blooming now and they are monsters compared to these little guys!

Found a few of these plants today. Flowers are still closed very tightly. Will check back in a few days. My first yellow lady slipper find so am very excited.

This little patch of small yellow ladyslippers are the only ones I have seen in the area. This seems to be the outer fringe of their range.

I found one unusually small yellow lady's slipper, which I think is var. makasin, along a road next to a remote lake in central Cass County. The slipper itself looked to be 1-1.5 inches at the largest. I'm going back to measure it.

Follow up to May 31 posting - I went back and measured, and the yellow slipper is only 1 inch, so I feel sure it's var. makasin.

10 years ago they were prominent in the gravel shoulder in Kabetogama, near cannister site. Transplanted small group to similar conditions. Doing well,but have to be protected from deer.

I LOVE these dainty mini yellow orchids growing wild by our summer cabin on Lake of the Woods at Morson, Ontario (we have the Showy pink Lady's Slippers and larger Yellow Slippers also). I photograph them and paint them in watercolor. We're from KS but spend summers here...thrilling to see the gorgeous and unique wildflowers, weeds, insects, wildlife, etc. of this area.

I discovered quite a few on the ditch bank at my Dad's place in shotely township 2 miles south of upper red lake. None of us had ever noticed them before and they were down in the tall grass hard to see. As I was leaving the guy that mows the ditches had just mowed that section of the ditch. I couldn't bare to stop and look if they had made it.

On 6/1 17 I reported finding one var. makasin - small yellow lady slipper. I went back to the site this spring (6/2/18) and now there are seven!

The plant was in a ditch on a forestry road that is part of the local four wheeler trail. I was delight to see it.
