Herbaceous perennials are garden plants that die back to the soil line when winter temperatures arrive. The plants enter a dormant period and strengthen the root system while waiting for the coming of spring.
Herbaceous is any plant that makes new growth from ground level every year and all above-ground growth dies at the end of that season. Gardeners complicate things a little by usually applying the name only to fibrous-rooted plants, so although things like daffodils are herbaceous, they generally just get called bulbs.erbaceous is any plant that makes new growth from ground level every year and all above-ground growth dies at the end of that season.
