Satsuki is the Japanese word for fifth moon or May. In bonsai most usually applied to Azaleas because of their tendency to flower for about a month in May.
Azaleas are members of the Rhododendron family, and are generally thought of as small varieties of that family. However many miniature Rhododendrons have been classified so this does not hold true.
Azaleas and rhododendrons are the same plant, both ERICACEOUS (lime-hating), with thousands of CULTIVARs. They are noted for the wide VARIETY and vibrancy of colours of FLOWERS which bloom mostly on "garden" specimens in mid-spring. Most popular for bonsai are the SATSUKI AZALEAs which are distinguished by often having multiple different coloured blooms on the same tree.
