For Your Garden - November 2019

Native plants provide beauty as well as food and shelter for wildlife. Native species are adapted to the Illinois climate. They require little or no watering and are resistant to drought, insects and most diseases. Because they are perennials, you can welcome their presence year after year.

yellow gentian (Gentiana alba)

Yellow gentian is also known as yellowish gentian and white gentian. This perennial herb has leaves in an opposite arrangement along the stem. The simple, entire leaves are lance‐shaped or oval. Leaves clasp the stem. The five‐parted, white flowers are showy. The fruit is a capsule. Yellow gentian may attain a height of one to two feet. It may be found at scattered locations statewide in Illinois growing in moist prairies and on rich, wooded slopes. Flowers are produced from August through October.
