Some species of Eucalyptus have showy flowers that appear at different times of year.
Silver Dollar Eucalyptus (Eucalyptus polyanthemos) - Growth
The genus, Eucalyptus, is a huge genus with roughly 600 species which gives it a variety of different growing needs; however, they primarily need full sun. All species are evergreen, but they may come as small shrubs or huge trees. Many Eucalypts can withstand windy and dry climates, which makes them great candidates for windbreaks. In less hardy areas, grow plants in a cool greenhouse with a minimum temperature of 35°F (2°C). During the day, set temperatures between 41-50°F (5-10°C), and at night, keep the temperature at 36°F (2°C).
Silver Dollar Eucalyptus (Eucalyptus polyanthemos) - Planting
When planting a Eucalyptus tree, you must know how big your tree or shrub will get. Some trees can grow as much as 10' per year and can get rather large. Make sure your Eucalyptus has plenty of room to grow wherever it may be planted.
