Needs staking first 23 years.* (Underlining added for emphasis). From Australia. With excessive water, trees can become chlorotic. Sun. 20o F."

They are great foundation or specimen plantings.* They need little water after they are established.* As you can see from the above source, staking is required during the first couple of years.* Many experts will advise the removal of the nursery-supplied support stakes (the bamboo pole shown in the first photo, below) when planted and to replace these with the typically recommended two- or three-stake support system located away from the root ball loosly supporting the tree (allowing some sway, but no permanant "lean"). * These trees, when young, have a willowy trunk that needs support for a period of time.
This is what they are like from the nursery, the typical size when planting.* This is NOT me in the photo

After a couple of years...
And here are their flowers in spring and early summer...
