Hi Anthony and Nerida,
Gardenias will grow to a range of heights. There is a small variety called Gardenia radicans which is a ground cover. Gardenia florida will grow to 1 metre and the largest variety Gardenia magnifica will grow to 1.5-2 m. Visit you local nursery who should have the full range of gardenias available and then you can choose what hedge height you prefer. Gardenias grow best in soil with a low pH that is free draining. Morning sun is best however they will grow in full sun if they are watered regularly.
