Description

Cardinal Flower (Lobelia cardinalis) is a real showstopper, shooting up 3–6 foot stalks of bright red, tubular blooms from late spring through early fall. It thrives in rich, wet soil—think rain gardens, streambanks, or pond edges—and full to partial sun, and it’s a magnet for hummingbirds, butterflies, and bees while deer generally leave it alone. This short‑lived perennial often spends its first year on leafy growth before really flowering, but it self‑sows easily, so you’ll get new plants popping up each season. Just give it a layer of mulch to help it through frost, and you’re set. Heads up: like all lobelias, it’s mildly toxic if eaten, so keep it away from curious pets.

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.

Seeds & Seed Mixes:

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

Live Plants:

Live plants are available year-round while inventory lasts and ship to select Midwest states due to plant health and hardiness considerations. 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.

States we ship live plants to:
Missouri, Minnesota, South Dakota, North Dakota, Nebraska, Kansas, Oklahoma, Arkansas, Tennessee, Kentucky, Illinois, Indiana, Ohio, Michigan, and Iowa.

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.

Live stakes ship to the same select Midwest states as live plants due to establishment requirements.
