How to discern such lovely tall growing shrubs from those which remain small?
I live in Murwillumbah, ( 2484) very northern NSW. In some gardens in Murwillumbah, I have seen azalea shrubs (in full sun) to have grown to almost house-high. How to know what plant to buy which will grow into a large shrub?

You will want to make sure to look at the tag on the plant for plant height. If the plant does not come with information, then you will have to ask someone working in the garden center to help you to find a plant that will stay within your height range.
Alternatively, you can search for specific shrubs that will be in your height range, and usually come up with quite a few results.
