Like many California natives, Whitney’s clarkia is surprisingly easy to grow when you match its natural preferences:

Getting Whitney’s clarkia established in your garden is straightforward:

  • Timing: Direct seed in fall or early spring when soil temperatures are cool
  • Seeding: Scatter seeds on prepared soil surface and lightly rake in
  • Spacing: Allow natural spacing as seeds germinate, or thin to prevent overcrowding

Important Conservation Note

Because Whitney’s clarkia is considered rare, it’s crucial to source seeds or plants responsibly.
