I have both varieties in my garden (windward Oahu, Kaneohe). Both were acquired from local botanical gardens, the tree form from Ho'omaluhia, and the bush from Foster Gardens, Honolulu, both at their annual plant sales.
The tree form is compact and slow-growing, having reached 4 feet and bloomed twice in 3-4 years.
The bush is enormous: 30+ feet across and 20 feet high, although in a cramped area (planted before I knew how big it got). It blooms profusely 8-10 x/ year scenting the air for blocks around.

The correct name for this gardenia is Gardenia lamingtonia.
Two forms are known. Large flower and smaller.
G. tubifera is five petaled and has wider, ovate petals with downturned tips. From sepals to bloom face its throat measures
3-4 inches. It is a small tree form up to 15 feet with infrequent, sparse blossom set.
G. lamingtonia grows to 20 feet with very heavy bloom set every 2-3 months in Hawaii.
