Lapageria rosea 'Tierra del Fuego'

New in my collection in 2006, flowers are a large well formed red but I can find no further information. Like  all Lapageria it needs cool moist acid soil in shade, absolutely hates direct sun for any length of time, although the top of the plant will be happy if the lower part is shaded. The flowers are waxy bells and it is in flower from July through to March. Due to its flowering period and the fact that new growth can be frost damaged it needs a sheltered wall (min -4c) or grow it down the shady end of the conservatory.
The species comes from Chile; the majority of wild plants have cherry red flowers with occasional pale pinks and whites. Introduced around 1847.
My plant came direct from Chile, I can find no record of the origins
