  • Posted by Baja_Costero (Baja California - Zone 11b) on Mar 9, 2020 11:45 AM concerning plant:
    Very common shrubby succulent Euphorbia from Madagascar. Stems are 4-5 sided, with bristles along the ribs and pale leaf scars. Leaves on young plants have prominent white veins (thus the species name), but these are mostly absent on older plants. The cyathia appear close to the tip and are short and brownish red, with bright white exserted stamens and styles.

    This species does better in relatively low light (for a succulent) compared to many other Euphorbias and enjoys more water than many desert plants. It is self fertile and may produce an abundance of volunteer seedlings scattered about at some distance from the mother plant.
