Compact aster Plant Care
Eurybia compacta G.L.Nesom
Updated · Sources · How we source care data
Eurybia compacta, commonly known as the slender aster, is an herbaceous perennial native to the eastern United States from New Jersey to Georgia. It is commonly found along the coastal plain in dry sandy soils, especially in pinelands. While it is not considered to be in high danger of extinction, it is of conservation concern and has most likely been extirpated from much of its original range. The slender aster was for a long time considered to be a variety of E. surculosa, but Guy Nesom's recent research within the genus has shown that it is distinct enough to be treated as a species. It has also been shown to be related to E. avita and E. paludosa.

How Do You Repot a Compact aster?
Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
How Do You Propagate a Compact aster?
Compact aster can be propagated through division, seeds. Similar propagation techniques also apply to bigleaf aster plant care, which shares the same genus.
