Euphorbia stygiana | Azores Spurge

$0.00

DESCRIPTION
Euphorbia stygiana forms bold rosettes of glossy, dark green leaves carried on sturdy stems, creating a deep-toned presence through the year. In late spring to early summer, broad clusters of greenish chartreuse bracts with burgundy glands surround small central flowers. Subtle reddish tones may appear along stems and leaf margins as the season progresses.

Endemic to the Azores in the North Atlantic, it reflects the mild, ocean-shaped climate of volcanic islands where it evolved on sheltered slopes and in open woodland. Steady evergreen growth and measured flowering lend lasting structure to borders, coastal gardens, and protected urban plantings across changing seasons.
