  • Posted by Baja_Costero (Baja California - Zone 11b) on Mar 25, 2020 10:57 PM concerning plant:
    Small shrubby Euphorbia from Madagascar with somewhat tomentose (furry) leaves bearing intricate vein patterns. All above-ground parts of the plant (stems, leaves, stipules, cyathia) are furry. Described in 1995, from northeastern Madagascar. Stems are branched and rebranched (with time), with 4-8 bristly ribs and prominent leaf scars. Cyathia are reddish or yellow, closed between bracts, pointing away from the stem.

    Similar to E. capmanambatoensis and closely related to the red-flowered E. neohumbertii. Filed within subgenus Euphorbia.

    This plant is partly or totally winter deciduous, depending on conditions, but it does not require a winter dormancy in mild climates, and will tolerate some winter rainfall there. Like other relatives of the crown of thorns, it enjoys regular water during summer and benefits from good drainage. An excellent container plant, easily propagated from cuttings.
