A very interesting tree for use in your rainforest zone, Stenocarpus davalliodes Fernleafed Scenocarpus/Fernleaf Oak. This beautiful tree is endemic to NE Qld rainforests and although not on the current list as threatened, is still regarded as rare. Stencocarpus davallioides will grow well beyond 10 metres in its native zone around Atherton North Qld. Its mature leaf resembles (at least to me) that of the Silky Oak and bares clusters of cream flowers.
The fascinating feature of this tree is its juvenile leaf which closely resembles the Hare’s Foot Fern. By keeping the tree pruned it takes on the appearance of a giant clump of Hare’s Foot. Hence it’s name davallioides which refers to the similarity of the leaf in the genus Davallia. Scenocarpus davallioides would prefer a rich loamy soil but as long as it is well drained I think it would adapt. It will take some chill in winter but I am not sure as to its frost tolerance. I would be using this plant as part of the understory in dapple light though it will tolerate a sunny spot. Would make a fantastic specimen in a large pot where the fern like foliage could be enjoyed close up.
Now a super tough species that will make any garden look respectable. I have often used this group in landscapes around factory sites or public carparks because of their resilience to a wide range of conditions including neglect, they still perform well and tolerate harsh soil types and windy spots, even salt spray. So if you are a newcomer to gardening or need a plant that will tolerate mostly anything, including vehicle pollution try the forms of Rhaphiolepsis. They won’t let you down. Rhaphiolepsis umbellata, “Yedda” or “Yeddo”, is an evergreen, medium to tall shrub, dense foliage, dark green attractive leaf, white flowers somewhat fragrant, sun to part shade, and a little prune to shape.
Rhaphiolepsis “Apple Blossom” a tidy rounded shrub to around 1.5 metres likes a light prune after its pink flowers have finished, sun to part shade. Good for pots or even low hedges.
Rhaphiolepsis “Cosmic White” trade name a cultivar of Rhaphiolepsis indica, a good form for hedges, bears larger white flowers (bigger than “Yedda”) requires very little care, no diseases maybe the occasional caterpillar and you only need to prune to maintain its shape. Hardy plants for difficult spots.
