Bearded Iris: ‘Spartan’

26 May

In Greek mythology, Iris was the goddess of the rainbow; the flower’s name pays homage to the many colors of irises that exist. In the language of flowers, an iris is viewed as the bearer of good tidings–a reflection of the goddess Iris’ other role as messenger to the gods. I was swayed to include irises in the garden solely because of their beautiful display–but if they also bring good luck, even better.

This year, I added a maroon-colored bearded Iris: ‘Spartan.’ Its name is a nod to ancient Greek history, though their enemies would probably not have equated Spartan warriors with good tidings. I at least hope the name means the three plants I now have in my garden will be hardy.

They are the first bearded irises I have had the pleasure to observe at close range, and though they are now at the end of their brief blooming season, I kept an eager eye on them from the moment they were first in bud:

With the standard removed and this section of the plant opened up a bit (right), it is easier to see how the beard–and the color pattern–point the way to the nectar at the inner base of the flower. The stamen (male reproductive organ) with its pollen-covered anther is visible at the back, just in front of another petal-like structure that is called the style arm. The style arm is a highly modified pistil (female reproductive organ). Normally it’s a tight squeeze for a bee to get to the nectar; as it heads downward, it will brush up against the anther and get dusted with pollen. When the bee visits another iris, the pollen on its back rubs off and attaches to the sticky stigmatic lip (the arched line toward the top of the style arm, below the upper crest), allowing pollination to begin.

Rudbeckia maxima: A Natural Bird Feeder

21 Sep

Last year I discovered that while my two bird feeders were quite popular, there was another very attractive source of seeds in the yard that was equally as appealing to certain birds: the Rudbeckia maxima (Giant Coneflowers) I had planted near a wrought-iron fence. I watched one day as a small bird flew by, grabbed a stalk in its little talon, pulled the stalk over to the fence, and perched there, nibbling seeds off the cone.

Since then, I have been happy to share the flowers with the birds. I can see the attraction; the Rudbeckia are stunning–they are tall (about 7 ft.) and cheerful, with clumps of silvery-blue foliage and lovely yellow ray flowers pointing down from the base of the cone. The cone starts off light green but then turns dark brown as the plant matures and the seeds come in. And then, it’s buffet time for finches, chickadees, and other birds.

Even after the petals have dried up and fallen off, Rudbeckia maxima seed heads can play a striking role in the autumn garden: here is a whole one and a section in close-up.
