A cultivar of Euphorbia Trigona, ‘Rubra’ displays flushes of burgundy as well as the standard green tones. Sometimes even individual leaves can be half deep green and half burgundy, which makes for a very interesting feature plant in any potted arrangement or garden design. Euphorbia is actively growing in summer, once the days are longer and hotter the winter dormant Euphorbia will begin to grow leaves along its spines and slowing start looking more lush and healthy. Winter dormancy really takes hold on this Euphorbia if it is exposed to full sun all year round. You will notice your Rubra will be completely leaf free in winter or at least will loose a lot of its leaves in this time.
Euphorbia does not handle long periods of drought like other succulents, it may need to be watered weekly in its summer active growth season. Rubra still needs well draining soil and always allow the top soil to dry out between waterings. Reduce watering in the winter months when the plant is dormant.
