Cider gum is bushier than most other eucalyptus species, according to Monrovia. It grows to a maximum average height of 50 feet -- some have been known to reach 75 feet -- and a maximum average width of around 30 feet. The shrub features attractive, dark green narrow leaves and white, spring-blooming flowers. Multiple shrubs planted close together work well as a visual screen or sound barrier.
Cider gums are hardy in U.S. Department of Agriculture plant hardiness zones 8 through 10. They can tolerate temperatures as low as 5 degrees Fahrenheit, according to Stanford University's Buildings and Ground Maintenance.
The cider gum is excellent for troublesome spots in your landscape because it doesn't need much watering but can also tolerate poor drainage. Unlike many other eucalyptus species, it's a great lawn plant. The cider gum grows best in full sunlight.
Eucalyptus oil is highly toxic if ingested, according to the North Carolina State Cooperative Extension Service. The toxic chemicals include the eucalyptus oil and cyanogenic glycoside. People or pets who eat part of the plant may suffer from nausea, diarrhea or even a coma, but only if large amounts of the plant are ingested. The oil may also cause a minor skin rash that should last for only a few hours. If you suspect your child or pet has eaten part of the plant, contact your doctor or veterinarian immediately.
