With typically only 21 to 100 known occurrences and between 3,000 to 10,000 individuals in the wild, this plant needs our protection.

If you’re interested in growing largeflower speedwell, please ensure you source it responsibly from reputable nurseries that propagate their plants rather than wild-collecting them. Never harvest this plant from the wild – doing so could harm already vulnerable populations.

Perfect Garden Roles

Largeflower speedwell shines in several garden settings:

  • Rock gardens: Its compact growth habit makes it ideal for tucking into crevices and small spaces
  • Alpine gardens: Naturally adapted to harsh conditions, it thrives in mountain-style landscapes
  • Native plant gardens: Perfect for Alaska-focused or northern native plant collections
  • Ground cover: Can spread to form attractive low carpets of foliage and flowers

  • Water: Regular watering, especially during dry spells, but avoid soggy conditions
  • Maintenance: Generally low-maintenance once established

Benefits for Wildlife and Pollinators

The flowers attract various small pollinators, including native bees and flies, providing important nectar sources. By growing this native plant, you’re supporting the complex web of relationships that make Alaska’s ecosystems thrive.
