Photo of the Week – April 19, 2012

We’ve been a little short on April showers this spring, but the warm weather is bringing on plenty of flowers.

False Solomon's seal flowers.

The little prairie garden in our yard is greening up much faster than it normally does.  Today, the False Solomon’s seal was blooming, and the thin clouds overhead made good conditions for photography.  White flowers can be tricky to photograph because it’s difficult to keep the white from washing out, even in diffused light.  To compensate, I underexposed the photos (made them look a little darker than I normally would) and then brightened them carefully with Adobe Photoshop.

False Solomon’s seal (Maianthemum stellatum) is a widespread species that occurs across most of North America.  In Nebraska, it is found in both grasslands and woodlands.  Along the Platte River, I see it both on the tops of sand ridges in lowland meadows, as well as in the nearby cottonwood woodlands.  It’s also common in the oak woodlands in the eastern part of the state.

False Solomon’s seal is named for its similarity to the true Solomon’s seal (Polygonatum biflorum), which does have a somewhat similar appearance, but the flowers of true Solomon’s seal emerge from the axils of the leaves rather than from the top of the plant.

No, someone didn’t toss a mess of orange plastic twine out in the prairie, though that’s certainly what it looks like.  That crazy jumble of orange is the parasitic plant called dodder (Cuscuta sp.).  It has no chlorophyll, so is unable to photosynthesize – hence the non-green color.  Instead, it attaches itself to its host plants and extracts food from them.  The dodder in our prairies appears to favor goldenrod and sunflower species.

Dodder has no leaves, and only tiny flowers that produce tiny seeds.  We’ve never harvested the seeds, but dodder shows up in our restored prairies anyway.  I think that’s great.  The fact that a parasitic plant can find and colonize amongst its host plants is just another indication that our restored prairies are functioning well.  I’ve never been able to find anyone who knows much about how its seeds travel, but there is a lot of speculation that they hitch rides on people, equipment, and animals.  Whatever – it seems to work!

I have a soft spot for species like dodder that have made their own counter-culture way in life.  (I no longer remove cowbird eggs from grassland bird nests for the same reason – so sue me.)  A plant that doesn’t even have leaves?  What a great idea!  Why make your own food if you can get it from someone else??

I’ve never seen evidence that dodder is eaten by anything, though I have to assume that something feeds on it.  Otherwise, we’d probably be swimming in dodder – and that might reduce its attraction to me just a little!
