The house was built as an orangerie for overwintering cold-sensitive plants. Today, plants that tolerate cool winter temperatures are kept here permanently. The temperature lies between 12°C and 25°C with large daily and yearly fluctuations.
The Agathis house comprises mainly species from the subtropical region across Oceania. Have a look at the 100-year-old Queensland kauri pine (Agathis robusta) and the big-leaved podocarp (Podocarpus macrophyllus), which are both coniferous trees.
Queensland kauri pine (Agathis robusta)
The most precious adornment in the Agathis house is the more than 100 year old Queensland kauri pine tree. It belongs to the gymnosperms and bear its seeds in cones. The genus Agathis is native to the southern hemisphere. The stem is straight and does not branch off except in the crown and is rich in resin, attributes that makes the tree valuable for timber production.
Wollemia (Wollemia nobilis)
Belongs to the conifers and is one of the world´s rarest plants. It was discovered in 1994, just north of Sydney, Australia. Nobody had seen anything like it before, except as fossils. Its closest relatives had gone extinct long ago, and finding a living Wollemia is comparable to finding a living dinosaur!
