Eucalyptus vernicosa - Varnished Gum (Tasmania) This is a small, shrubby euc from the windswept alpine ridges and heaths of Tasmania where it grows almost exclusively above the timberline.  It grows to about 4 - 15' tall, and usually wider than high.  It is closely related to E. johnstonii and E. subcrenulata, and has leaves the same shade of deep shiny green.  The leaves are small and may remain round and juvenile throughout the life of the plant, or they may become pointed with short petioles.  It is a very slow-growing species in cultivation - probably the slowest-growing euc listed on this page, and perhaps the slowest-growing euc all around, usually growing less than 1' per year.  It takes many years to finally reach the size of a small tree, and can generally be considered as an attractive shrub in cultivation.  It is, however, very hardy, tolerating temperatures down to somewhere in the neighborhood of 0°F.

Eucalyptus viminalis - Manna Gum, Ribbon Gum, White Gum (southeast Australia) This fairly well known species is a large tree with usually smooth bark and billowy masses of foliage.  The predominantly white bark peels attractively strips leaving cream, pink and tan patches.  It grows very rapidly and can reach a height of 160'.  The juvenile leaves are opposite, but green, and long and narrow.  Overall a rather large, beautiful, messy, soft-outlined tree.  Closely related to E. dalrypmleana and E. rubida, and easily confused with them when mature, but generally not quite as hardy.  However it is certainly one of the more impressively-tropical-looking hardy eucs and should be tried more in colder climates.  5 to 15°F.  Ssp. cygnitensis - Rough-barked Manna Gum is a smaller tree from western Victoria and South Australia, and is probably not as hardy as the best provenances of E. viminalis ssp. viminalis.  It has rough bark and a low-branching crown.
