Plants in Early Stages

by Carl Strang

Part of a naturalist’s craft is learning to identify things. We progress from entire birds to single feathers, from entire mammals to skulls and other bones. Plants have many stages, from seed to seedling to developing plant to plant in flower, each with many parts. Ideally a naturalist can identify any of these stages or parts, and have a story to tell about them. I have shared some of this learning process, most recently comparing some winter plants with the same species in bloom. One of these was the elm-leaved goldenrod. Here it is as it begins to grow in spring.

Earlier in the season I photographed some of the plants that spend the winter as rosettes, or clusters of leaves hugging the ground so as to minimize damage through exposure to the season’s stresses. Here is winter cress.

Here is the white avens.

There is wonder to experience in following the development of any living thing, and it’s well worth the effort needed to get familiar with all the elements of our local landscape. Also, there are practical applications. For instance, when an animal is eating leaves from a rosette in January, the information is useless unless one can read both the animal’s tracks and the identity of the food plant. Plus, there is always something new to learn, so the process is ever stimulating.

Two Winter Goldenrods

by Carl Strang

In recent weeks I have been comparing the dead stems of some winter forbs to their appearance when in bloom. I have a couple more today, and then probably will adjourn the topic until next winter. Earlier I addressed northeast Illinois’ most abundant goldenrod species, the tall goldenrod. Today I will review two more members of genus Solidago. When in bloom, stiff goldenrod’s flowers look like this.

The leaves are thick, rounded and stubby, on relatively stout stems. This species is a prairie goldenrod, often a prairie indicator because its unpalatability to livestock kept it around when other native prairie plants were consumed to local extinction. Here it is in winter.

The second goldenrod is a woodland species. Elm-leaved goldenrod’s flower sprays remind me of fireworks, meteors or comets.

In winter that color is gone, but the plant still has an interesting, distinctive appearance.

I enjoy studying winter botany, but the time has arrived to look for the new year’s new flowers.

Early Autumn Woodland Flowers

by Carl Strang

We’re turning for home in this first season of inventorying the forbs of Mayslake Forest Preserve. First flowering dates of spring- and summer-blooming plants are safely in the record for comparison to future years. Today’s installment of woodland species has a distinctly late-season quality to it. Nothing announces the end of summer better than the goldenrods. Elm-leaved goldenrod is abundant in both the north and the south units of Mayslake’s savanna.

I’ll feature tall goldenrod here, though this species has such a broad ecological range that I could have included it among the prairie plants as well.

Late boneset can grow in open places, though at Mayslake I am finding it best represented in the north savanna.

While most members of genus Rudbeckia are associated with meadows and prairies, the brown-eyed Susan is a woodland species.

One of my favorites in the autumn woodlands is wingstem, and I was happy to find some growing at Mayslake.

The only species in today’s group that is not in the sunflower family is the woodland knotweed.

While this plant can be very abundant in forests, I have found only a relatively small number in Mayslake’s savannas.
