General Notes

Strawberry Tree is an attractive small evergreen shade tree, with its shiny dark green color and attractive bark and multi-trunk branching habit. The flowers and fruit are also attractive highlights during the year. Once established, it is a very durable tree. The fruit drop tends to be messy near drives or walkways. It may require regularly scheduled light top-trimming (but not necessarily shearing) of vigorous top shoots to maintain its height below 25'. It is resistant to oak root fungus.
