The stems of Phedimus takesimensis shoots also become woody.

Phedimus takesimensis shoots are a large to medium-sized species, and the stems become woody. 　 The stems that have grown this year also become woody at the base, and because the woody part is long, new shoots will appear from parts farther away from the base of the plant. In older plants, the stems initially stand upright, but as they grow, the branches lose support and grow into an open shape. The plant often has a donut-shaped grass appearance with an open center. This phenomenon is not observed in  Phedimus takesimensis shoots that grow epiphytically on rocky areas. It is speculated that in the natural environment of rocky areas, nutrients are scarce, and in order to withstand natural phenomena such as strong winds, the stems are short and have a lot of fiber, making them difficult to fall over.
