Description

Black‑eyed Susan (Rudbeckia hirta) is a cheerful biennial wildflower that grows 1–3 feet tall and blooms from June through October across most of the U.S. and much of Canada, featuring bright yellow petals and a dark central disc that draw in butterflies, bees, and birds. It thrives in full sun and well‑drained soil—though it will tolerate partial shade and occasional moisture—and is prized for its drought and heat resistance, deer tolerance, and its knack for self‑sowing at the end of its two‑year cycle. While it can spread vigorously under ideal conditions, proper drainage and occasional thinning will keep it in check.

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.
