Euphorbia obesa comes from the Eastern Cape and is protected by international Cites legislation. Euphorbia obesa is a fascinating plant with nearly spherical grayish-green stems with transverse bands of different shades of green. They grow in full sun and partial shade. In habitat, they are hard to see as they are camouflaged. Euphorbia obesa grows well on a sunny windowsill or outdoor area. Needs to be brought inside when the weather is cold as they are not frost tolerant. Euphorbia obesas like a shale soil with gravel. Water lightly in summer and keep dry in winter. It can stay in the same pot for years. Often, especially in bright light, these bands can be an attractive contrasting purplish-bronze. Great conversation piece. Known as the "Baseball" plant. Responds well to warmth, with its active growth period in the late spring and summer months. Porous soil with adequate drainage. Requires bright light for best appearance, and should be given a winter resting period at which time less water should be given. Protect from frost.  All Euphorbias contain a white sap that can be irritating to eyes and mucous membranes. If contact is made with this white sap, take care to not touch face or eyes before washing hands with soap and water.  Although they are known to be slow growing, my experience has seen them grow faster than other Euphorbias.
