Lapageria rosea 'Collinge' (co-YIN-gay)

New in 2007 to my collection this has white flowers with red edges. Like all Lapageria 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 place (min -8c) 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.

The cultivar Lapageria 'Collinge'  is also known as Dr Bullock or Mejilla Roja (Red cheeks) in the UK it has also been sold as 'Wisley Picotee' 
Elbert Reed had this plant in the collection at El Vergel, Chile. My plant came to me from Berkeley botanic garden California as 'Collinge' and another from Penheale in Cornwall as 'Wisley Picotee'. They appear to be one and the same, there is no record of when or how RHS Wisley came to have this plant, if you know the answer I would love to hear from you!
