    I enjoy growing and sharing this plant with others. To prevent excessive reseeding, either cut off the flowers to enjoy inside or deadhead the plant after the blooms fade. Dig up unwanted plants in the spring while the plant and rootball are small and share them with other gardeners either here on ATP or locally. Be sure to let them know about its invasive tendencies and how to keep it in control. It's a fun plant for kids, as the flowers remain in the position that they are turned, hence the name obedient plant.

    Use false dragonhead in a border or allow it to spread in large clumps in a naturalistic meadow garden.

    a good plant for some late color in the perennial garden
    spreads well and may need some management to keep from taking over.
    also a good source of nectar for bees
