The eucalyptus silver drop plant (Eucalyptus gunnii), sometimes called cider gum, is actually a tree native to Tasmania. It has round, silver leaves and attractive bark that ranges from gray to a combination of orange and pink. White flowers appear on the tree during spring and summer. The foliage of the silver drop plant gives off a pleasant menthol scent, even after it is dried for use in flower arrangements. This plant does best in full sun and well-drained soil.
Water the eucalyptus silver drop plant just before you are ready to remove it from its growing container. Dig a hole that is slightly wider and the same depth as the container.
Place the root ball into the planting hole at the same level as it was previously growing. Tamp the soil down and water until it is very moist, but not soggy. Add a 2-inch layer of lava rock to control weed growth.
Water whenever the top inch of soil feels dry to the touch.
Prepare the plant for winter by placing three stakes around the tree in a triangular shape. Cut the bottom out of a clear plastic bag and pull it over the stakes. Add a 2- to 3-inch layer of organic mulch around the base of the plant to help protect the roots.
Remove the protective covering in early spring, after the danger of hard frost and very cold temperatures has passed.
