Believer™ Purple Aster (Symphyotrichum novi-belgii 'Believer Purple') brings stunning late-season color with its rich purple petals encircling bright yellow centers. Blooming from late summer into fall, this compact perennial grows 12 to 18 inches tall and spreads up to 18 inches, making it perfect for borders, containers, and fall displays. Its neat, mounded growth habit and profusion of flowers provide contrast in any garden. Hardy in USDA zones 4–8, Believer Purple Aster is an excellent choice for adding cool-toned beauty to autumn landscapes.
This New York Aster cultivar thrives in full sun but tolerates light shade, especially in warmer climates. Its narrow, lance-shaped green leaves form a dense mound that stays lush throughout the growing season. Resistant to deer and rabbits, this low-maintenance perennial attracts butterflies and other pollinators with its plentiful blooms. Ideal for mass plantings, pollinator gardens, and decorative pots, it pairs beautifully with ornamental grasses, sedums, and other fall perennials.
Believer Purple Aster Care
Plant Believer Purple Aster in well-drained, moderately fertile soil with a pH range of 5.5 to 7.5. Ensure the planting location receives at least 6 hours of sunlight daily for the best floral display. Water regularly to maintain evenly moist soil during the growing season, but avoid waterlogging. Applying a balanced, slow-release fertilizer in early spring supports healthy growth and prolific blooming. Mulch around the base to help retain soil moisture and regulate soil temperature.
Pinch back stems in early summer to encourage bushier growth and a greater number of flower clusters. After the first frost, cut the plant back to the ground to promote fresh regrowth the following spring. In containers, provide consistent moisture and consider staking if the stems become leggy.
Believer Purple Aster Spacing
For borders or mass plantings, space plants 12 to 18 inches apart to allow for airflow and healthy spread. In container plantings, use a pot that is at least 12 inches wide and deep to support the plant’s root system and mounded form. Closer spacing can create a dense, colorful display, while wider spacing highlights the individual shape of each plant.

We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die.

The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability).

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
