Incredibly fast growing tree with handsome, blue-green foliage in elegantly sweeping branches thats are ideal for cut foliage in flower arrangements.

The bark is shed in long strips to expose a smooth white trunk and branches. White flowers occur from winter to summer. 

Typically an inland subspecies of Eucalyptus globulus occurring at higher altitudes than the other subspecies.

Native to Victoria and Southern New South Wales.

Prefers a medium to heavy moist soil in an open sunny position, drought and frost resistant.

Eucalypt's germinate readily from seed and are generally considered one of the easiest natives to grow from seed.

Depending on the species Eucalyptus seed comes in various sizes from very fine to several millimetres long.
As a rule of thumb seed that is fine should be sown on the surface of a porous mix and not buried. Seed 1 to 2 mm in diameter can be covered very lightly and seed from 2 mm up can be sown to a depth of the seed width.

Cold stratification of 21 days is recommended for this Eucalypt. Cold treatment is not critical for germination to occur but should give increased germination rates.

This is cool mountain species of Eucalypt that in its native range has a cold winter prior to germinating in spring. This can be replicated by cold stratification in the refrigerator for 28 days. Alternatively over wintering in the garden in cold climates will assist germination.

Although seed can be sown most of the year in Australia seed is generally best sown in spring or autumn in temperate climates, avoid the coldest and hottest months of the year. The optimum germination temperature for germination is around 16-22°C

  1. Sow seed on surface of a porous seed raising mix. The seed will lodge in the the pores of the mix once watered.
  2. Sprinkle a very light covering of the seed raising mix over the seed if required to hold the seed in place. Do not bury seed deeply.
  3. Water with fine mist spray to avoid disturbance of the seed.
  4. Ensure the mix is moist but not water logged.
  5. Place the container in plastic bag.
  6. Place the bagged container in the refrigerator for 28 days.
  7. Place in a warm shaded or semi shaded position to avoid dying out.
  8. Keep warm & moist, avoid drying out or waterlogging the growing mix.
  9. Germination generally occurs in 10-28 days when moved to warmer temperatures after the period of cold treatment.

General note: Seeds of many natives are dormant and require specific conditions or pre-treatment for germination.
Do not be too hasty to discard seed that does not germinate, seeds will often lay dormant until the conditions are similar to their natural requirements for germination to occur. Containers put to one side will often surprise long after they were discarded.
