Aster 'Vasterival'


The Symphyotrichum 'Vasterival', commonly known as the Aster, is a decorative flowering plant noted for its showy appearance. The plant produces a profusion of daisy-like flowers, which typically feature a central disc of small, compact yellow florets surrounded by slender petals that radiate outwards. These petals can range in color from shades of purple and lilac to rosy pinks and sometimes even white. The foliage of the Aster is also distinctive. Leaves are generally medium green and can be lance-shaped or oblong, with a smooth or slightly serrated edge. The overall growth habit of the plant tends to be bushy with stems that branch out, creating a full and lush appearance. The leaves and stems work together to form a backdrop that further accentuates the colorful floral display when the plant is in bloom. As a perennial, the Aster returns year after year, each time producing its signature blooms that attract pollinators such as bees and butterflies. The blooming period for the Aster typically occurs in late summer to fall, providing a late-season burst of color to gardens and landscapes.

During hot or dry spells, watering frequency may need to increase to every few days. The amount of water should be about 1 gallon per plant for each watering, ensuring that the water penetrates deeply into the soil to encourage robust root growth.

  • sunLight

    New England asters thrive best in full sun conditions, where they can receive at least 6 to 8 hours of direct sunlight daily. They can tolerate some light shade but will have the best flowering and growth in a location that is unobstructed from the sun's rays.

  • circleLife cycle

    The Symphyotrichum 'Vasterival', commonly known as the Aster 'Vasterival', begins its life cycle when seeds germinate in the spring, emerging as small seedlings. As temperatures warm, these seedlings develop into young plants with foliage that grows progressively through the spring and summer. During late summer to fall, the Aster 'Vasterival' enters its flowering stage, producing an abundance of daisy-like flowers that attract pollinators such as bees and butterflies. After blooming, the flowers will develop into seed heads, and as the plant senesces in late fall, these seeds are dispersed by wind or wildlife, enabling the propagation of new plants. Over winter, the above-ground parts of the perennial plant die back, but the root system remains alive, storing energy for the next growing season. In spring, the plant will sprout anew from this robust root system, repeating its life cycle.

      Early spring

    • The most popular method of propagation for Symphyotrichum 'Vasterival', commonly known as the Aster, is by division. This is typically carried out in the springtime as the plant emerges from dormancy and when you can see the new shoots beginning to form. To propagate by division, carefully dig up the parent Aster plant, making sure to keep a generous amount of soil around the roots. Gently separate the clumps into smaller sections, ensuring that each new section has a good amount of roots and at least a few shoots or leaves. These divisions can then be replanted at the same depth they were growing at before, spaced approximately 18 inches (about 45 centimeters) apart to allow for growth and airflow. Water the new plants thoroughly after planting to help establish them. Divisions will typically take root and start growing within a few weeks, provided that they have sufficient water and are not exposed to extremes in temperature.
