Hi Randy,

Your plant with the distinctive square stem, is a Euphorbia Leuconeura or Madagascar Jewel Plant. It can grow as tall as 6 ft, resembling a small branching tree. Although Madagascar Jewel plants prefer dry soil, they are less susceptible to over-watering than many other Succulent PlantsLearn the definition of a succulent plant and why they are called a "fat plant.". This unique Euphorbia propagates by shooting its seeds into the air and doesn’t mind low humidity. bright indirect lightVery few houseplants should be placed in direct sun. High light refers only to bright indirect light since direct sun often burns the leaves of indoor houseplants. An area that is too hot and dry encourages Spider Mites and causes blooms to quickly fade. A northern exposure really doesn't provide enough light for high light plants. These plants need to be placed directly in front of an east-facing window, within 1-3 feet of a west-facing window, and within 5 ft. of a south facing window.

Some plants contain chemicals such as oxalates, solanine, glycosides, or alkaloid lycorine that may cause vomiting, nausea, diarrhea, swelling and redness of the mouth, throat, and lips, and trouble breathing. Touching parts of certain plants, especially the sap, may cause various skin irritations. The weight and age of the human or pet involved, and the part and amount of plant eaten determine how severe the reaction to the toxins will be. Although plants may be listed as non-toxic, they can still cause individual allergic reactions.
