Camellias. Tsubaki. The Japanese call them 'Samurai Flowers' because of their propensity for losing their heads whole.
I love them; possibly because they flower in the middle of winter. Harbingers of the much longed-for warmth of spring. Soon we will emerge from fuyu gomori 冬篭 - our warm cuddly winter hibernation - and enjoy days in the sunshine once more.
