Eucalyptus crenulata

Eucalyptus crenulata or Crenate Gum Tree is native to Australia where it grows in wet to swampy soils along watercourses. It forms a small tree whose leaves are a beautiful silvery, ashy colour, ovate or heart-shaped and slightly dentate on the edges. They form a dense crown of highly ornamental and unique foliage. It is also appreciated for its spring flowering in white pompoms, its good hardiness, -12 to -15° (10.4 to 5 °F) C, perhaps more, and its ability to grow in very wet or heavy soils, even limestone. It enjoys full sun and also grows in ordinary, drier soil.

Eucalyptus crenulata is a large bush of the myrtle family, native to Victoria in Australia, with a very restricted range, northeast of Melbourne, to the Acheron River Valley. It grows there along watercourses, in moist to wet, even swampy and asphyxiating soils. It is also occasionally found on drier soils. It reaches 10 m (32 ft 10 in) in height and 5 to 6m (16 ft 5 in to 19 ft 8 in) in span at maturity with moderately rapid growth. The young shoots of this eucalyptus carry evergreen foliage, composed of heart-shaped or ovate leaves with crenate edges, blue-green, silvery and ashy in colour, opposite when they are juvenile and alternate at maturity. They are aromatic when crushed. Flowering occurs between April and June on plants a few years old. These are round, petal-less flowers composed of a multitude of cream-white stamens tightly packed like pompoms. They bloom between the leaves, grouped in 3s all along the shoots and are followed by the formation of large green fruits shaped like cones, turning brown when ripe. The grey-brown bark is rough and cracked.
