Sparse Orchids after a Mild Winter

Certain plants seemingly do well no matter how much or much little care we give them in our gardens. One great example of a plant that seems to do great year after year is the low-growing sedum. It doesn’t matter if the weather has been too hot or too cold or too rainy, because this yellow-flowering succulent grows and gets bigger each and every year. We have some really poor soil up here on the mountain ridge and this plant excels even without fertilizing it.

The weeds in the fields in early Spring are the same way. They seem to grow into huge colonies no matter what kind of weather they experienced. Sure, their fastest growth might be delayed or the blooming times might differ slightly from year to year, but in the main they’re strong growers.

Other plants, not so much. An example of finicky plants, which seem to do well only in periodic years, are members of the orchid family, Orchidaceae. To them, it seems that the conditions must be just right for them to grow really well and bloom beautifully.

For example, the colonies of moccasin flower or pink lady slippers that we enjoy each year had a paltry blooming season this year. We can’t blame it on the mild winter or lack of rain only because we can’t go back and test for that. But, in comparison to the average year we didn’t get to enjoy much of them.

We’re left wondering if the weather is to blame or if these plants just can’t manage blooming and growing really well every year. This year we saw 11 lady slippers with only 6 of them blooming in an area that more typically has a couple of dozen plants with about half of them flowering.

Another orchid that we have the pleasure of seeing on our rocky land is the whorled pogonia and they didn’t flower this year at all. Only 14 plants were counted in an area that has seen 4-5 times as many orchids in a good season.

I’m wondering whether other nature children see such a great difference in the presence of orchid plants from year to year. Has this been a poor orchid blooming year in your area?

Pink Lady Slipper or Moccasin Flower Blooming in Pennsylvania, 30 April 2010.

Checking on the huckleberry plants the other week I was pleasantly surprised to see the Pink Lady’s Slipper or Moccasin Flower, Cypripedium acaule. After I saw one I looked for more lady slippers and found a number of them right along the trail near the stone monolith.

Pink lady slippers don’t bloom every year. Typically a third to a half of the plants in an area will bloom while the others just display their two thick leaves.

The pink lady slipper is fairly common in our territory here in the Appalachian Mountain ridges. I’ve seen them blooming plenty of times, but never saw one that formed a seed head. That may be a result of searching them out when they’re blooming and not paying much attention to them the rest of the year.

Here, there were two plants that must have formed seed heads the prior year. The brown seed heads were still attached to the plants.

Note in the image above that the brown seed head rose to about 16 inches.

The pink lady’s slipper was also flowering along the slope of the trail on the east side of the Box Huckleberry Natural Area.

Each Mother’s Day I look forward to seeing the native moccasin flowers blooming. Since Mother’s Day was celebrated on May 9, 2010 the Pink Lady’s Slippers bloomed right on time.
