Growing Grinnell’s Beardtongue Successfully
If you’ve sourced your plant responsibly and you’re ready to give it a home, here’s how to help it thrive:
Ideal Growing Conditions

- Water: Drought-tolerant once established, but provide regular water the first year
Planting and Care Tips

Once established, you can cut back significantly on watering.
This low-maintenance native may even reward you with self-seeded offspring if conditions are right, though remember that any extra plants should stay in your garden rather than being shared widely, given the plant’s conservation status.
