Red Gum Tree Seeds

Red Gum Tree (Eucalyptus camaldulensis), also known as River Red Gum, is one of Australia's most iconic eucalyptus species and is prized for its rapid growth, attractive peeling bark, and excellent adaptability. Native to riverbanks and floodplains, this hardy evergreen tree thrives in warm climates and is widely planted as a shade tree, windbreak, timber tree, and ornamental landscape specimen. Its fragrant foliage attracts pollinators, while its striking white to cream-colored flowers provide seasonal interest. Red Gum is also valued for its drought tolerance once established, making it an excellent choice for large landscapes and reforestation projects.

Germination Instructions

Red Gum seeds benefit from scarification prior to sowing to improve moisture penetration and encourage more uniform germination.

1. Scarify the seeds gently before planting.
2. Fill seed trays or small pots with a well-draining seed starting mix.
3. Sow the tiny seeds on the soil surface and lightly press them into the growing medium without covering, as light aids germination.
4. Mist the soil thoroughly and cover the container with a humidity dome to maintain consistent moisture.
5. Keep temperatures between 70–80°F (21–27°C) in a bright location.
6. Maintain evenly moist, but not saturated, soil until germination occurs.
7. Remove the humidity dome once seedlings are established and provide plenty of sunlight.
