Eucalyptus or Gum Tree
The evergreen gum tree species are native to Tasmania and Australia where they can be found almost everywhere from the wet coastal regions to the dry desert areas. Their size ranges from small shrubs to gigantic trees. E. gunnii is an extremely popular species because it tolerates temperatures as low as -15° C (5° F). It is a fast-growing tree that can be cut back to keep the size down. The blue-green juvenile leaves are striking but the yellowish-whitethat appear in winter are rather inconspicuous. Eucalyptus trees love a warm, sunny position. If grown in containers, they must be watered regularly and generously. If left to dry out, they will probably not recover. Use lime-free water and lime-free , and feed sparingly. In milder regions, eucalyptpus plants can be left outdoors; otherwise they need a light, well-ventilated place with a temperature of 5-15° C (41-59° F). Seeds sown in spring germinate very quickly.
