A shrubby almost woody Euphorbia with large opulent green leaves and in spring honey scented chartreuse flowers. To 6′ tall and forming a patch as wide. Very lush appearance for a plant that is actually drought adapted when established. This is an incredibly rare plant in its habitat in the Azores. About twenty plants remain in the wild and that is all. A great reason to grow this large plant. Broken leaves emit white sap. Protect from subfreezing wind – a south or west aspect is best in a sheltered position. Grows quickly with light irrigation in soil that is enriched but drains. Established plants require water just once every few weeks, Very pretty under a low window where the honey like fragrance can be enjoyed. Might be deer resistant but protect this lush shrub in the beginning. Blooms late spring and is wonderful with other bold plants for full sun . Pair with our native elk clover (Aralia californica) and hardy banana (Must basjoo). Excellent performance at the Oregon coast and lovely backed by a stone wall. Regrows from the base if established plants freeze back. Be patient, recovers in mid-spring. Wonderful garden plant.
