Here is a flower of Camellia sasanqua 'Yuletide' looking lovely at a local nursery. I've one in my garden but I planted it in the bright sun this spring only to have some other plants put on a big burst of growth and shade the poor thing out causing it to go on strike bloom wise. It's on my list of things to move to a sunnier location this spring.
The same nursery also had quite a few plants (Monrovia) labeled "Pink Yuletide Camellia" which is a sport of 'Yuletide.'
Looking more closely at the tag, one might notice that the real name of the plant is C. sasanqua 'MonDel' and in searching the web, I learned from Monrovia's site that it's also called Pink-A-Boo(the wretching may now commence.) Monrovia claims that it's wonderfully fragrant. Maybe if it had been warmer it may have been but I didn't detect a fragrance.
Having no idea what MonDel might mean, I decided to see if the plant might give me some sort of clue. The following pictures were taken of plants that were not under cover and rain had been allowed to fall on them.
Although the effect of the flowers doing this is kind of interesting up close, from a distance, it looks a little like someone threw browinsh tissue paper on the plants. Many camellias drop their spent petals to the ground creating a delightful sea of color beneath the shrub; others have a somewhat less charming habit of holding on to their dead brown blooms that get wet and remind me of wet crepe paper(not pretty.)
Probably these plants were fairly new arrivals and the uncovered ones suffered some shock at being shipped to a cooler area. The slight difference in the covered and uncovered area may have saved the dry pink ladies from fading. They look like faded plastic flowers in a way. (Do we all remember plastic flowers?)
