Camellia sasanqua 'shishi gashira' is one of my favorite camellias because it blooms in December, January and sometimes
into February, adding a lovely bright color to the garden when there's usually nothing else blooming. Unlike most sasanquas, it has a dwarf, spreading habit reaching from 3.5'- 6' tall and wide. My mature Shishi Gashira is on the small side because I prune it once a year, immediately after blooming, to keep it full and compact. My neighbor's which was planted at the same time but has never been pruned, is the larger size and more wispy. I find a place for this plant in most of my designs. I love that it's also winter hardy and can be used in a part sun/part shade location.
My camellias have tons of buds but nothing looks like yours. I don't think my camellia is happy here in Florida.
