Euphorbia myrsinites (AGM) is a glaucous succulent which, in the right place, will seed itself everywhere. Like most Euphorbias it bears lime green flowers in the Spring. It likes full sun and well drained soil.
To encourage upward growth, pinch off new buds when they appear below the top leaves on the plant stalk. With proper care, in three years your Avocado will grow to an elegant, large-leaved houseplant about 3 feet tall.
