More about Euphorbia trigona
Euphorbia trigona 'Royal Red' is a beautiful rich burgundy cultivar of Euphorbia trigona. A cultivar occurs when an environmental or other factor causes changes in a plant. A cultivar is not a hybrid; It is rather a change in the DNA of the cells of one unique plant. In the case of the 'Royal Red', rather than the forest green of Euphorbia trigona, the stem is a lovely marbled burgundy with undulate, reddish burgundy margins and some small burgundy leaves during the active growing season. Excellent for use in bright areas of the home or office or as a patio plant in more temperate regions. In time, becomes a much branched shrub to 6' in height. Responds well to warmth, with its active growth period in the late spring and summer months. Porous soil with adequate drainage. Water thoroughly when soil is dry to the touch during active growing season. 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. Remember, all Euphorbias contain a white sap that can be irritating to the skin and eyes. Wash hands immediately in soap and water if contact is made with the sap. Avoid touching face and eyes while handling Euphorbias.
