I feel grateful to live in a place with all four seasons. It is a miraculous thing to watch the changing colors of fall leaves, wake to snow quietly blanketing the valley, or see the first shoots of green in the spring. At heart, though, I am a summer girl. I absolutely adore plants and gardening. I make my living teaching people about medicinal herbs and they are one of my deepest passions. This makes fall a bittersweet time of year for me, and by winter, I am yearning for The Green. Over the years, as I have hiked or skied many a winter trail, I have enjoyed trying to ID plants in the wintertime. While evergreens such as Oregon grape, uva ursi or conifer trees are easy to identify, many deciduous plants can be identified if you look closely.

Wintertime plant ID has helped me notice other details about plants that I tend not to notice in the summer. Noticing a plant in the winter makes it easier to recognize plants in the early spring as well. This can help with foraging spring greens and planning for summertime harvesting spots. In general, annual plants (plants with a life cycle that lasts a single year, or season) leave less trace than many perennials. Both biennials, which have a two-year life cycle, and perennials, that grow for more than two years, tend to have more substantial parts to recognize over the winter months. I’m amazed at how often I will see small green leaves around the base of a perennial plant in the winter. Many plants that are not considered evergreen will never the less do this. Sometimes I will even dig down into the snow and see new green leaves, a sure sign to me of the optimism and tenacity of our plant friends.

Some key things to look for:

There are many other details we use to accurately determine the genus and species of a plant, but the points below are some of the key features I look for in the winter. To make sure you have an accurate ID, it is always best to go back and make a proper identification in the summer.Ecology: Where the plant is growing can help you narrow down possible species. Questions to ask include:

• Where is the plant growing and what is around it?

• Are there other plants that you commonly see with it?

• Does it thrive in the mountains, by meadows, along a river, in a forest, on a hill?

• Does it like a wet or dry environment?

• Does it prefer the open areas, or need the shade of other plants or trees?

General form:

• What are the plant’s size and shape?

• How large does it grow?

• Is it a tree, shrub, vine, grass, herbaceous?

• Is there a stray leaf or two still hanging on the plant, or around the base that will help you with identification?

• Can you feel the texture of a leaf (hairy, smooth, prickly)?

Flower or Seed Heads:

• Can you see any dried flower heads or seed heads?

• Are the flowers or seeds singular or in clusters?

• Are the flower heads composite (one flower head containing many small flowers: think sunflower)?

• Do the flowers spread from a common point, somewhat like an umbrella (Think wild carrot)?

• Do the seeds have hairs? Wings? Patterns? A shell?

Stems:

• If there are smaller stems off of the main stem, are they opposite each other, or do they alternate up the stem?

• Does the plant have a square or round shaped stem?

• Does the plant have thorns?

• Are the stems woody?

• Does the plant have a particular color?

Fruits or Cones:

• Look on and around the plant for fallen seeds, fruits, nuts, shells, or cones.

• Note the color, size, texture.

Identifying plants in the winter is not only fun, it adds to the skills of an herbalist to be able to recognize plants in all seasons. I hope this inspires you to get outside this winter and go find some herbs!
