The Proteaceae Woodland, Beds 107a & b, one level down into the rock garden below the Visitor Centre viewing deck and to the east. Also, the entrance to the Gondwana Walk near the Conifer Cultivar beds
A generous covering of rich pink blossoms draws attention to this warm-temperate rainforest dweller.
These trees are usually grown from seed. The plants will tolerate short cold periods and require a consistent water supply, shelter from strong winds and well-drained, fertile soil.
The largest of our four Dorrigo waratahs in the Proteaceae Woodland at Mount Tomah was planted in 1989 and has flowered well since 1999. The three younger specimens and those near the upper entrance to the Gondwana Forest also flower well.
Proteaceae is an ancient Gondwanan family, and at the Blue Mountains Botanic Garden Mount Tomah we seek to interpret, though plants, the evolutionary links between the countries which once comprised the supercontinent of Gondwana.
This is an opportunity to see a rare and very handsome native member of that family which is not often found in cultivation.
