Is sage native to Idaho?

Sage has grown increasingly popular in recent years due to the popularity of certain new age practices like smoke cleansing. Smoke cleansing with sage originated as “smudging” in certain Native American tribes but is a closed practice. Smoke cleansing can be done by anyone, so long as the sage is ethically sourced.

Greater sage-grouse (Centrocercus urophasianus) is native to Idaho and some other types of sage are also found in the state. Sage and sagebrush are not actually the same plant, so please take note of this. Sage is a spice, whereas sagebrush is a high desert shrub. However, white sage is suitable for parts of Idaho Highway Districts 1, 2, 3, 4, 5, and 6. It is used in part of the Idaho roadside restoration and prevention programs.

What vegetables do well in a garden in Idaho?

If you’re wanting to plant a vegetable garden in Idaho, you can do well with crops like beets, carrots, lettuce, onions, chard, spinach, all of the cabbage family, peas, turnips, and radishes. There are other crops that can do well in warmer weather months, but you must ensure all signs of frost are completely gone before seeding or transplanting. For warm-weather crops, consider corn, peppers, eggplant, tomatoes, beans, melons, and squash.
