For those who are not familiar with the species, Serissa is native to open sub-tropical woodlands and wet meadows in southeast Asia, from India, and China to Japan, making it a perfect candidate to be grown indoors as a tropical bonsai. It has very small leaves and a rough texture to the bark (reminiscent of an old oak tree in nature) making it perfect for bonsai culture. Its flowers are small (in scale with the rest of the tree) and can be white, pink, and/or double blossoms depending on the variety. Its leaves can be solid green or variegated depending on the variety as well. It can be fussy on its conditions and will let you know by dropping leaves, but will spring back readily when you improve the conditions. It should be kept in bright indirect light and consistently moist.
Here are pictures from the “Making a Tropical Bonsai” class. Thanks to the ladies who attended, we had a wonderful time. The pre-bonsai stock was really exceptional for this one, with good-sized trunks and natural branching.
