Platycodon, tangerine

桔 is composed of 木 (wood) and 吉 (lucky). 木 denotes a plant, while 吉 signifies goodness, virtue, and good fortune. Thus, 桔 forms an ideogram representing a plant that brings health and good luck—used to denote a medicinal plant (as in Platycodon) or citrus fruits whose golden color symbolizes wealth and prosperity (as in tangerines).
