- Description
-
Valerian is easily grown in average garden soils in full to part sun. Its preference is full sun, with consistently moist conditions, and soil consisting of fertile loam but can adapt to less ideal circumstances. It can be grown in part shade, however, the stems may flop. The more shade, the more this condition will increase.
It is a non-native herb that has escaped cultivation and has spread primarily in the northern US as it prefers cooler weather and abundant rainfall. It spreads by rhizomes and seeds and can be weedy. It is listed as a noxious weed in Connecticut and Wisconsin.
It is grown medicinally for the sedative effects of the drug valerian that is obtained from the roots. Other uses are in foods, perfumes and teas. An oil obtained from the leaves and root is used as a flavoring in ice cream, condiments and baked goods.
Insects, Diseases, and Other Plant Problems: No serious insect or disease problems. Can become weedy and invasive. Its presence in the wild may displace native plants.
When used as a medicinal, prolonged use can lead to addiction. Adverse effects can include headaches, nausea, agitation, heart palpitations, and insomnia.
