Whorled wood aster (Oclemena acuminata) is a perennial native to Quebec's shaded forests, typically inconspicuous but notable for its resilience. This species reaches a height of 75 cm and is distinguished by its narrow, acuminate leaves, which are a glossy dark green. At the end of summer, small white flowers with yellow centers appear, providing a valuable nectar source for pollinators in the understory. The whorled wood aster prefers rich, well-drained soils that are often slightly acidic, thriving particularly in deciduous or mixed forests, adding a touch of lightness to shaded areas.
Ecological Role
In its natural habitat, the whorled wood aster plays an essential role for forest wildlife and flora. Its inconspicuous yet nectar-rich flowers attract several species of pollinators, including native bees and butterflies, who appreciate its late blooming. This plant also contributes to the stability of forest soils, especially in shaded environments where few other species thrive. It enriches the biodiversity of the understory by forming natural colonies without becoming invasive, making it an ally for Quebec’s forest ecosystems.
Whorled wood aster seeds require cold stratification to ensure germination. See the cultivation notes below for more details.
