Sea of Tranquility (tree peony), bloom detail
Sea of Tranquility (Registered in 1996 by William Gratwick, an American breeder. Parentage of the original seedling is unknown. Said to have first bloomed in 1960)
Descriptions of this white semi-double tree peony tend to be hyperbolic, which is an indication of the high regard in which it is held. It blooms quite early (immediately after Hephestos in the NA Peony Garden), and lasts a relatively brief time.
The feature I want to focus on by selecting this shot for the APAD gallery is the magenta sheath that encloses the carpels, or more correctly the ovaries that form the base of the carpels. The emerging stigmas match this sheath in color. By being surrounded by the pale white or slightly pink filaments that support the yellow anthers, this purple sheath stands out like a beacon. Just outside the ring of filaments, there are purple flares at the bases of the petals. Note also that this bloom is already beginning to shed pollen.
