Description

Sweet Black-Eyed Susan (Rudbeckia subtomentosa), also known as Sweet Coneflower, is a hardy native perennial that adds golden-yellow color and pollinator support to prairies and gardens alike.

Standing 3–5 feet tall, it features sunny yellow petals encircling a rich dark center. Blooming from late summer into fall (Aug–Oct), it provides nectar and habitat for bees, butterflies, and beetles.

This deer-resistant, drought-tolerant species thrives in full sun and medium-dry to medium-moist soils—perfect for Midwest landscapes.

Also known as: Sweet Coneflower.

Seeds & Seed Mixes:

Seeds and seed mixes ship nationwide, year-round, typically within 3–5 business days. If you would like to postpone a seed mix shipment until fall, please note this at checkout.

Live Plants:

Live plants are available year-round while inventory lasts and ship to all states except California, Arizona, Oregon, Washington, Nevada, Alaska, and Hawaii. After your order is placed, we’ll contact you to coordinate a spring shipping window, as many plants are overwintered and ship once dormancy breaks.

Estimated shipping for 2026 plant orders begins in mid-April, weather permitting.

If you’re looking to secure plants in advance or need larger quantities for a project, we offer contract growing options. Contact us to discuss your needs and request a quote. Additional species not listed online may also be available through contract grow.

Live Stakes:

Live stakes are available by request only and must be ordered by submitting a contact form. Ordering is open seasonally from November 1 through February 28. A minimum of 100 stakes per order is required, with at least 25 stakes per species.

Live stakes ship only to the following states: Missouri, Minnesota, South Dakota, North Dakota, Nebraska, Kansas, Oklahoma, Arkansas, Tennessee, Kentucky, Illinois, Indiana, Ohio, Michigan, and Iowa.

PLS stands for Pure Live Seed, an industry-standard measure of seed quality. It reflects the portion of seed in a batch that is viable and capable of germinating.

What this means for you: when you purchase 1 lb. of PLS seed, the physical weight of the seed you receive will be slightly more than 1 lb. That’s because we account for non-viable seed and natural inert material upfront, so you receive a full pound of live, plantable seed.

Many companies sell bulk seed by total weight, which can include filler and non-viable seed. By pricing based on PLS, we make sure you’re getting exactly what you paid for—high-quality native seed with more predictable, successful germination.
