hearded a few times about that plant but it's difficult to grow I think.
it grows on Juan Fernandez and that haves a real sea climate.
another special plant from the Juan Fernandez islands is the Juania Australis (palm) wich dies when the temperature is for a long time above 30 degrees or under the -5 degrees.
i dont know of that is the same by this plant.

Here's what I was able to learn on the "gardening on the edge forum".

[Yunquea tenzii] lives on top of El Yunque ("Anvil") mountain. During P. Dalton's expedition of February 15th 1999 a total of 23 adult specimens were counted, as well as 100 seedlings. Seedlings, though, seldom reach adulthood. CONAF´s trials to grow seedlings in the San Juan Bautista nursery in Robinson have yielded no results. Six seedlings were collected during the expedition but all al them perished due to their new environment and massive phytofagous insects' attacks. The last surviving seedling (lower picture) died in the beginning of 2002.

Y. tenzii is a typical example of geographical speciation in isolated conditions. Certainly this species didn´t retire to El Yunque's summit after being decimated by natural or anthropic causes, but it virtually speciated from another Compositae species in a markedly different environment from the other habitats in Robin Crusoe's island, when the mountain was higher and therefore had higly differing orographic climates. 2 or 3 million years ago the island's highest elevation used to be 2.000 metres above sea level.

There are similar speciation examples in the tepuis of Venezuela, Guyana and Brazil.

El Yunque's summit can be considered an island inside an island, and therefore Y. tenzii's is a very localized macroendemism which can be explained by the geoclimatic isolation of the summit.

Looks to be a near impossibility outside of it's native habitat.
Cheers, Barrie.
