You see chicory on the roadside during the morning commute, a splash of bright blue. Coming home, you don't notice it. When you think about it, the blue flowers aren't generally out in the fields either.

There are lots of places to see in Michigan. I attended the University of Michigan and over the years visited many parts of the state. I had the opportunity to return this fall. The trees were tall and green, the forest dotted with meadows and ponds.
Here is a look at central Michigan habitats, roughly the area near Grand Rapids.

When I was a beginning gardener, decades ago, I tried to grow all the spices of my kitchen shelf: sage, rosemary, thyme, oregano and so on. I have had oregano in my gardens ever since.
Common oregano, also called Greek oregano, pot marjoram, and wild marjoram, is Origanum vulgare in the mint family, Lamiaceae (also called Labiatae). Origanum is the Greek name for the plant, although you can read the more romantic explanation that it is a combination of óros and gános meaning "mountain splendor" or "mountain joy," perhaps both are true. The species epithet, vulgare, means "common." Oregano in native to southern Europe where it has a number of close relatives, such as sweet marjoram (Origanum majorana).

But weather and climate are complicated.
