Any ideas for a summer flowering, fragrant tree here on the sunshine coast. Should not grow bigger than around 20 ft.
If there was time to wait for it to grow up and get old enough to bloom, and you had a shady spot Rhododendron auriculatum has large, fragrant trumpets as late as August. Otherwise: Trees x Chitalpa tashkentensis Magnolia grandiflora Stewartia Vitex agnus-castus Shrubs Buddleja davidii Callistemon Clerodendrum Clethra Philadelphus Ref: SUNSET WESTERN GARDEN BOOK Plant Selection Guide, Landscape Plant with Showy Flowers, pp. 74-75 Most trees will exceed 20 feet, some shrubs will grow that tall. Lofty Buddleja and Philadelphus are seen down here.
Chitalpa tashkentensis...good suggestion Ron! This is such a cool tree. Planted one in a large container a few years ago and it is superb. Its really rare here so I had to buy it when I found it. The flowers are second to none. Luke
