Growing Tips & Guides

Description

Product Overview

Stoneroot (Collinsonia canadensis), also commonly known as Richweed or Horse Balm, is a perennial herbaceous plant native to eastern North America. Belonging to the Lamiaceae family, this woodland species is recognized for its broad green leaves, upright growth habit, aromatic foliage, and delicate pale-yellow flowers.

Stoneroot Seeds offer gardeners an opportunity to cultivate a distinctive woodland perennial suited to shaded garden settings, botanical plant collections, and naturalistic planting arrangements. The plant develops upright stems with opposite, oval-shaped leaves and produces loose clusters of small flowers during the warmer growing season.

Collinsonia canadensis is particularly suited to woodland gardens and partially shaded landscapes where its foliage and subtle flowering characteristics can complement other shade-tolerant plants. Its perennial nature makes it an interesting choice for gardeners developing established woodland-style planting areas.

    How to plant your seeds

    Follow these simple steps to give your seeds the best start.

    1. Prepare your soil & tray

      Fill trays or small pots with seed-starting mix. Press gently to settle—no need to pack tight.

    2. Sow seeds at the right depth

      Plant roughly 2–3× the seed’s width deep. Tiny seeds can be pressed lightly into the surface.

    3. Water & keep warm

      Mist or bottom-water. Cover until sprouting if the packet suggests it. Keep in a bright, warm spot.
