Eucalyptus grandis seed

Eucalyptus grandis, commonly known as the Rose gum or Flooded gum, is native to the east coast of Australia where it occurs naturally as a fast-growing tall tree of coastal and subcoastal wet forests sporadically distributed from near Newcastle in New South Wales north to south eastern Queensland with an outlying occurrence on the tablelands of northern Queensland. It is one of the premier forest species in Queensland and New South Wales growing to 55 m in height with a mature trunk ranging from 1 to almost 2 metres in diameter. Its form is excellent with tall, straight, clean holes up to two-thirds of the total height.

The bark is thin and deciduous, shedding in strips to expose a smooth surface marked with flowing patterns of white, slaty gray, terra cotta, or light green. Occasionally a "stocking" of light-gray, platelike or fissured bark persists over the basal 1 to 2 m of the trunk. Branchlets can be either glaucous (coated in a bluish bloom) or non-glaucous.

Juvenile foliage is ovate, 4 to 14 cm in length and from 2 to 8.5 cm wide, darker green above. Adult leaves are spear-shaped, 8 to 18 cm in length and from 1.5 to 4 cm wide, glossy, darker green above and paler below. The flowers are white and appear in late summer and autumn.
