Asters and Goldenrod


 The asters are beginning to bloom among the goldenrod. Here, the purple flowers of a lone New England Aster pops out in the yellow field of goldenrod.

A beautiful symbiosis of color, as the goldenrod seems to allow a spotlight on the aster.

Why do asters and goldenrod look so beautiful together?

That was the question Robin Wall Kimmerer (author of the much loved and acclaimed book "Braiding Sweetgrass") said she wanted to answer, when asked why she wanted to become a botanist during her freshman entrance interview for college. 

Of course, the "real" scientist interviewing her scoffed at that answer. 

But... why do goldenrod and aster bloom together, the colors yellow and purple complementing each other so well?

It's almost as if some intelligence designed it that way. Mother Nature is such an artist.

Other asters also bloom at this time, but they are mostly white-flowered. Some of the "asters" are fleabanes, which are related but in the Erigeron genus. They can be distinguished from the true asters by the fact that their flowers have many more petals.

Tall Boneset, aka Tall Joe-Pye Weed also blooms white in the meadows now. A closely related species, White Snakeroot, lights up the edges of the woods with its fuzzy white flowers. 

The most famous of our yellow flowers, of course, is the sunflower -- rather sunflowers. So many species of sunflower populate the meadows and roadsides that it's nearly impossible to tell which is which. Except for our common, annual sunflower, Helianthus annua, with its large, dark center. Many of the other sunflowers are perennials, including sunchokes (most commonly, Jerusalem artichoke) which provides a tasty tuber. 

But these are not the flowers Robin Wall Kimmerer expressed curiosity about when she sought to be a botanist. It was the beauty of the asters and goldenrod growing together that most impressed her. 

So, why do they look so beautiful together?

Did they evolve together for our benefit?

Not likely. We, perhaps, simply evolved in order to be able to appreciate their beauty.

Precious

 


It's paw paw season here in Northeast Kansas, and some people are out hunting for this precious treat, trying to beat the local wildlife to the ripening fruit.

Maybe 15 years or so ago I discovered a couple of paw paw trees growing just beyond the edge of the woods around our house. I noticed the first one because of its deeply colored, bell-shaped flowers that are large enough to be seen from a moderate distance. Even though paw paws are native to the eastern third of Kansas, I had never seen a paw paw tree before.

I was delighted to discover the tree's identity. The paw paw is the largest native fruit in Kansas, and seems more like a tropical fruit than a temperate region one. The fruit is probably about the size of a medium to small orange, but oblong in shape (as you can see in this photo). It is sweet and custard-like in texture when fully ripe.

The tree I found in our woods never produced fruit, although it had numerous blossoms. And it died two or three years later. I discovered another one in another area nearby. It is still alive, but is struggling. This rocky hill is not the best habitat for a paw paw tree.

The paw paw tree does prefer a shaded habitat, but does best in rich soil, especially near water. I've heard that many can be found in the woods around nearby Clinton Lake.

About 10 years ago I planted a paw paw tree near our house, but out in full sun next to some other fruit trees, which are now gone. I shaded it when it was young, but a mature tree can handle sun. It started fruiting about three or four years ago, but not prolifically. We did get nine paw paws last year. Such abundance! About a month ago I found four paw paws lying on the ground beneath the tree. It was a hot day and they were lying in the sun. They still felt firm, although warm. I brought them in the house and set them on the counter. It was far too early to harvest paw paws, but they do ripen off the tree. In about a week they were ripe enough to eat. So we ate them. 

One paw paw still clung to the tree, and I checked it frequently, fearing squirrels or some other wild being would make off with it. Squirrels often steal apples from our tree.

A few days ago I couldn't bear it anymore and plucked the above pictured fruit from the tree. It is now ripening on the kitchen counter, and has softened some. Soon we'll feast on paw paw.
