Prairie Aster becomes a fall season focal point as myriads of light lavender and pale periwinkle flowers nearly cover the entire mounded plant.  The cool-colored petals encircle bright yellow centers that shift to rich burgundy after pollination.  Compared to many other Aster family members, Prairie Aster has sizeable blooms, often measuring ¾” inch and larger!  The fresh stems are a lively, bright green; mature stems become brown and can appear woody, but the plant is herbaceous. The fine-textured foliage provides a wispy, ethereal backdrop for summer blooms before setting its stunning flower display in autumn.   

Symphyotrichum turbinellum starts life, like so many things, as a little bit of scraggly growth.  Despite its homely beginning, this plant will continue to fill out and create clumps.  It grows well in full sun and partial shade; despite the name, Prairie Aster is more often found in dappled savanna-like settings.  Site conditions play a large role in the potential growing height, supporting stems ranging from 18 inches to nearly 4 feet tall!  S. turbinellum grows best in somewhat acidic, well-drained soils with plenty of rocky or gritty texture.  This Aster is a posterchild for spoiled native plants becoming lazy and somewhat problematic.  Rich, nutritious sites will create lanky stems that require staking.  Prairie Aster can easily be trimmed back by about one third in the spring season to maintain a shorter growing height.

As with all native Asters, this species is a keystone flowering plant that provides essential late-season fuel for native pollinators.  Prairie Aster produces copious amounts of both nectar and pollen – these resources attract a large assortment of native bees, honeybees, butterflies, skippers, and many other species.  Silvery Checkerspot and Pearl Crescent butterflies will lay their eggs on this and other Symphyotrichums.  Wild Turkeys will sometimes consume the seedheads and foliage of this plant.  Most Asters are susceptible to deer and rabbit browsing - protect Prairie Aster until it is mature enough to flower; after that, the plant population should be established enough to recuperate after any nibbling.    

Former scientific name: Aster turbinellus
Also commonly called Turbinate Aster, Lavender Aster, or Smooth Violet Prairie Aster

1 Question asked on Symphyotrichum turbinellum

What is the garden habit like? Is this aggressive or mellow?
Hi Pepper. Especially in a garden setting, most Asters can eventually self-sow so plentifully that they become a small nuisance. You should be able to curtail Prairie Aster from spreading by pruning and removing the deadened flowers before they set seed.


Growing your own plants from seed is the most economical way to add natives to your home. Before you get started, one of the most important things to know about the seeds of wild plants is that many have built-in dormancy mechanisms that prevent the seed from germinating. In nature, this prevents a population of plants from germinating all at once, before killing frosts, or in times of drought. To propagate native plants, a gardener must break this dormancy before seed will grow.

Each species is different, so be sure to check the GERMINATION CODE listed on the website, in the catalog, or on your seed packet. Then, follow the GERMINATION INSTRUCTIONS prior to planting. Some species don't need any pre-treatment to germinate, but some species have dormancy mechanisms that must be broken before the seed will germinate. Some dormancy can be broken in a few minutes, but some species take months or even years.

Seed dormancy can be broken artificially by prolonged refrigeration of damp seed in the process of cold/moist STRATIFICATION. A less complicated approach is to let nature handle the stratifying through a dormant seeding, sowing seeds on the surface of a weed-free site in late fall or winter. Tucked safely beneath the snow, seeds will be conditioned by weathering to make germination possible in subsequent growing seasons.

Dormant Bare Root Plants

We dig plants when they are dormant from our outdoor beds and ship them April-May and October. Some species go dormant in the summer and we can ship them July/August. We are among the few still employing this production method, which is labor intensive but plant-friendly. They arrive to you dormant, with little to no top-growth (bare-root), packed in peat moss. They should be planted as soon as possible. Unlike greenhouse-grown plants, bare-root plants can be planted during cold weather or anytime the soil is not frozen. A root photo is included with each species to illustrate the optimal depth and orientation. Planting instructions/care are also included with each order.

Potted Plants

3-packs and trays of 32, 38, or 50 plants leave our Midwest greenhouses based on species readiness (being well-rooted for transit) and order date; Spring shipping is typically early May through June, and Fall shipping is mid-August through September. Potted 3-packs and trays of 38 plugs are started from seed in the winter so are typically 3-4 months old when they ship. Trays of 32/50 plugs are usually overwintered so are 1 year old. Plant tray cells are approximately 2” wide x 5” deep in the trays of 38 and 50, and 2.5" wide x 3.5" deep in the 3-packs and trays of 32; ideal for deep-rooted natives. Full-color tags and planting & care instructions are included with each order.

*PLEASE NOTE: we are a mail order nursery and have no retail facilities, but you may pick up your order if prior arrangements are made. Pick up orders are subject to **MN Sales Tax.

Shipping & Handling Charges

SEED $100.00 and under: $5.00
Retail SEED orders over $100.00 ship free!

Custom seed mixes or discounted seed sales over $100, add 5% of the total seed cost
(for orders over $1,000 a package signature may be required)

BARE ROOT and POTTED PLANTS $50.00 and under: $9.00
over $50.00: 18% of the total plant cost. (For orders over $1,000 a package signature may be required.)

TOOLS and BOOKS have the shipping fee included in the cost of the product (within the contiguous US).

**We are required to collect state sales tax in certain states. Your state's eligibility and % will be calculated at checkout. MN State Sales Tax of 7.375% is applied for orders picked up at our MN location. Shipping & handling charges are also subject to the sales tax.

Shipping Season

SEED, TOOLS and BOOKS are sent year-round. Most orders ship within 1-3 business days.

BARE ROOT PLANTS are shipped during optimal transplanting time: Spring (April-May) and Fall (Oct). Some ephemeral species are also available for summer shipping. Since our plants are field-grown, Nature sets the schedule each year as to when our season will begin and end. We fill all orders, on a first-come, first-serve basis, to the best of our ability depending on weather conditions beyond our control.

POTTED PLANTS (Trays of 32/38/50 plugs and 3-packs) typically begin shipping early May and go into June; shipping time is heavily dependent on all the species in your order being well-rooted. If winter-spring greenhouse growing conditions are favorable and all species are well-rooted at once, then we ship by order date (first come, first serve). We are a Midwest greenhouse, and due to the challenges of getting all the species in the Mix & Match and Pre-Designed Garden Kits transit-ready at the same time, we typically can't ship before early May. Earlier shipment requests will be considered on a case-by-case basis.

*We are unable to ship PLANTS (bare root or potted) outside the contiguous US or to CALIFORNIA due to regulations.


We ship using USPS, UPS and Spee Dee. UPS and Spee Dee are often used for expediting plant orders; they will not deliver to Post Office Box numbers, so please also include your street address if ordering plants. We send tracking numbers to your email address so please include it when you order.
