This is Rosa roxburghii plena, which means the "double" form of the Chestnut Rose. It is named for the director of a Botanic Gardens in Calcutta, where the plant was brought from China, in 1814. You have to remember the colonial history of China and India for that to make much sense.Basically, early explorers and missionaries in China were acting as spies and thieves. They smuggled plants out of China. Consequently, as soon as possible after leaving China the plant samples were opened, and "grown on". Calcutta was a strategic port in British controlled India. Literally thousands of plants made this risky journey, before being shipped on more safely to Kew Gardens and other private gardens in England.
I have seldom bothered to photograph this Rose before. To be honest, it is one of a number of Roses which I ordered and grew on an experimental basis, and for their Novelty Value.
I knew it, vaguely, from having toured some old rose collections. I knew it was said to have bristly buds (hence the name, as Chestnuts have bristly burred coatings outside their smooth nuts. That's where the similarity ends.)
What I had not counted on is its hardiness and reliability and its ability to flower in deep shade. This plant is overgrown by other shrubs, yet it manages to flower for me, every summer.
It produces flowers with this luscious bright pink colour in the centre, but a light pale pink outer colour. I do not touch this plant from one year to the next - except to admire it occasionally as I walk past.
*****Here is another lovely little rose "Rosa Perle d'Or" which is so easy to grow that these flowers are coming from a foam box in which I placed some cuttings, several years ago. They survived the cutting and striking process, and then have survived total neglect since then. I kid you not. I have not touched these plants since laying down the cuttings.
Every summer these delightful small apricot-pink flowers appear. They are a little larger than the classic "buttonhold rose" (Rosa Cecile Brunner).
