Description

Water Horehound (Lycopus americanus), also known as American Bugleweed, is a native wetland plant that grows along streams, ponds, and marshy areas. It produces small white flowers along the stems during summer, which attract bees and other pollinators. While the flowers are modest, the plant plays an important role in wetland ecosystems by providing nectar and habitat.

Water Horehound grows best in full sun to partial shade and prefers consistently moist to wet soils. It spreads gradually by rhizomes, allowing it to form patches in suitable conditions. This species works well in rain gardens, shoreline plantings, and wetland restoration projects where native plants adapted to saturated soils are needed.

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.
