Eucalyptus deglupta RAINBOW TREE (20 seeds)

Rainbow Eucalyptus, scientifically known as Eucalyptus deglupta, is a non-hardy tree belonging to the Myrtaceae family. This highly unique, fast-growing tree is native to the island of Mindanao in the Philippines, but it is also found in French Polynesia, New Guinea, New Britain, Seram, and Sulawesi. It typically reaches between 7 and 15 meters in height.

This multicolor tree is famous for its smooth bark, which constantly peels away in strips. The exposed trunk progressively changes color—starting as a pale green, it darkens into bluish and purple tones, then shifts to orange and finally brown. This natural process explains its name.

Rainbow Eucalyptus seeds are brown and shaped like tiny water droplets. They are minuscule, measuring only one millimeter in length.

The tree produces small white flowers grouped in clusters.

Ecological Benefits and Sustainable Reforestation

In addition to its beauty, it plays a key role in biodiversity and atmospheric carbon capture.
It is a preferred species for reforestation in wetlands, combining environmental robustness with a fascinating aesthetic for an eco-responsible garden.

- Germination and Sowing:

• The most favorable period to sow Eucalyptus deglupta is from late May through the end of July.
• Sow the seeds on the surface without burying them (light-germinating) in a tray filled with very fine, slightly moistened peat-based potting soil.
• Water the planting using a spray bottle.
• The substrate must remain moist throughout the entire germination period.
• Place the tray in a greenhouse at a temperature near 30°C. Germination begins 3 to 6 weeks after sowing.

- Soil Type / Substrate:

It requires a very well-drained substrate rich in organic matter. For pot cultivation, do not forget to provide excellent drainage at the bottom.

- Exposure / Light:

This variety requires a lot of light; it is best to expose it to full sun whenever possible.

- Temperature / Hardiness:

Due to its exotic origin, it has low hardiness and must be grown in an environment where temperatures stay between 15°C and 30°C. Its USDA hardiness zone is 10 to 11, meaning it can only survive minimum temperatures of about 1 to 4°C.

- Watering / Irrigation:

This tree requires frequent watering in the summer; for pot cultivation, it may be necessary to water every two days. It is not necessary to provide extra water during the winter, as the risk of root rot is high during this period.

- Propagation / Reproduction:

There are two ways to reproduce this tree: either by cuttings (taking 15 cm branches and using the "smothering" or high-humidity method) or by sowing seeds.
