寒桜(カンザクラ; pronounced Kan-Zakura) means “Sakura in the cold season”.
In Tokyo, famous Sakura “Somei-Yoshino” blossoming begins at the end of March or the beginning of April, but you can see Kan-Zakura blossoming late in February.
I took these photos on Feburuay 24, in the Koishikawa Botanical Gardens, The University of Tokyo.
