I grow a camellia under the name Camellia japonica ‘Campsii Alba’. It is the same as one in Moyclare Garden in Liskeard that is known by the same name. It also matches two of the three plants under that name in the Mount Edgcumbe collection. (5B-004 & 5C-003)
The third plant in the collection (5D-004) is different but I think it is more likely to be the correctly named one, in spite of the weight of numbers. I am fairly certain that my plant and the two similar Mt Edgcumbe plants were propagated from the Moyclare plant.
The Camellia Register describes it thus:
“The flower is full, spherical, regular and formed like a perfect rosette. The colour is pure, milk white. The petals, disposed in 7-8 rows, are of average size, rounded, close set, regularly imbricated from the circumference to the centre. Very early flowering.”
It would be helpful if a size for the flower was given. My plant and its kin have been flowering since well before Christmas. The other plant does not flower so early, my pictures of it have been taken in April. Both forms have small, pure white flowers about 5-7cm across. The 5D-004 form is almost always a formal double showing no stamens in its centre but I have on just one occasion seen a fully open flower with some stamens at the centre. The Moyclare plant always has anemone form flowers.
The Moyclare plant is probably at least 50 years old and will have been planted by Moira Reid. It is about 4m tall and flowers freely every year over a period of up to three months. The leaves are quite small for a japonica, glossy and robust. It’s a very fine variety and I would love to identify it correctly.
