Euphorbia japonica aka Pineapple succulent. This little guy is so adorable. Makes a caudex with little chubby arms branching off. Yellow cyathia (flowers) Emerge from the top of each growing point over the leaves throughout the warm months. Euphorbia bupleurifolia is a relative. This is much easier to grow. Forms colonies of branches off the main trunk. Great bonsai! 4" pots.
