Eurasian bush honeysuckles (Lonicera maackii, L. x bella) We just refer to it as the Asian honeysuckle bush in Missouri.
It is native to Asia in northern and western China. This species poses a serious threat not only to the diversity of the ecosystems. It is listed along with Garlic mustard (Alliaria petiolata) as the Worst of Invasive plants for our state. The flowers are sometimes used by children, who remove the blossom by hand, and pull off the bottom to suck out the sweet nectar in the center. The red berries are mildly poisonous to humans and should not be eaten.
Japanese honeysuckle vine. It is native to eastern Asia including China, Japan and Korea. It is a twining vine able to climb up to 10 meters (33 ft) high or more. The root system is extensive and may be over 10 feet across and 3 feet deep.It will choke the life out of many trees and plants. It will spread itself via shoots, cuttings or seed. It will make layers on top of itself and suffocate or strangle small trees or bush. It can be controlled to some degree via labor-intensive methods such as cutting or burning the plant to root level and repeating at two-week intervals until nutrient reserves in the roots are depleted.
Leaves are opposite (2 leaves per node)
AllelopathyIs the suppression of growth of one plant species by another due to the release of toxic substances
One of the most allelopathic plants is Black Walnut (Juglans nigra). The chemical responsible for the toxicity in Black Walnut is Juglone (5 hydroxy-1,4 napthoquinone) and is a respiration inhibitor. Solanaceous plants, such as tomato, pepper, and eggplant, are especially susceptible to Juglone.
