PROO-nus ser-u-LAH-ta
'Sekiyama' Japan
Native to (or naturalized in) Oregon: 
  • Deciduous tree, 20-25(40)ft [6-7.5(12) m]; upright, branches stiffly ascending, spreading.  Leaves large, short tooth serrations, new leaves bronzy, may turn orange-bronze in fall.  Flowers deep pink, double (23-28 petals), 6.4 cm diam., 5 per pendulous clusters, blooms abundantly.
  • Hardy to USDA Zone 5   Considered the most hardy of the double types.   The most popular flowering cherry in Western countries.
  • Kanzan is a old Japanese poetic word meaning "bordering mountain".   The word conjured an image of a "native land or village of one's birth that lay in a valley" (Kuitert, 1999).  It is unclear why this word was applied to a cherry.  ‘Kanzan’ is also called ‘Sekiyama’ or ‘Sekizan’, and ‘Kwanzan’ is an obsolete spelling of ‘Kanzan’ (Kuitert, 1999).
  • A sport of 'Kanzan' with dark purplish leaves was named 'Royal Burgundy' and has been in commerce since about 1990.
  • Corvallis: SE entrance to Central Park
  • Oregon State Univ. campus: front of Bexell Hall; also along 15th St. between Campus Way and Jefferson Ave.
