November’s Weed of the Month, Oriental bittersweet (Celastrus orbiculatus), is a woody vine with colorful red fruit. It was brought to North America from the Asia and used as an ornamental plant. The attractive vines have been used for wreath decorations and in floral decorations; unfortunately, the plant has escaped cultivation and has become invasive in residential and natural areas in Minnesota.
Amur honeysuckle (Lonicera maackii) is one of four species of non-native honeysuckle listed as Restricted Noxious Weeds in Minnesota. It is native to Asia and was introduced to North America as an ornamental plant that was then widely planted for wildlife and erosion control.
St. Paul - The Minnesota Department of Agriculture (MDA) is warning residents about the dangers of poison hemlock (Conium maculatum), a toxic member of the carrot family. Residents should be on the lookout for the weed, take extra precautions when handling it, and not ingest any parts of the plant.
Last month we learned about how the cut-flower industry can be a pathway for new invasive plant introductions. A good example of a plant that got its start in the Midwest through this inroad is baby’s breath, Gypsophila paniculata. Baby’s breath has become a problem across the northern and western U.S. and is listed as a noxious weed by California and Washington. It is known to occur in Minnesota, but the exact distribution is unknown.

February’s Weed of the Month is about the poisonous ornamental plants that may be found growing in Minnesota community gardens. Some poisonous plants commonly grown in gardens have specific parts which are safe to eat (like tomatoes or other nightshades), while other plants are entirely poisonous. We will focus on plants which are wholly poisonous. The most common of these in Minnesota are castor bean, jimsonweed or Datura, and foxglove.
