How to Grow Exacum from Seed

Exacum is easy to grow from pelleted seeds, which make handling much simpler.

Sowing Tips:

  • Start seeds indoors 8–10 weeks before last frost

  • Sow on top of the soil—do not cover, as light aids germination

  • Keep soil moist and temperatures between 70–75°F

  • Germination usually takes 7–14 days

Once seedlings are established, transplant them into small pots or trays. When they’re well-rooted and past frost danger, plant them outdoors in partial sun or filtered light. Exacum appreciates consistent moisture but avoid soggy soil.

They’re ideal for:

  • Hanging baskets

  • Mixed containers

  • Window boxes

  • Shaded patios

  • Indoor windowsills

  • Compact habit

  • Blooms quickly from seed

  • Attracts pollinators

  • Long-lasting flowers
