Euphorbia hypericifolia
Native to the southernmost parts of the U.S., Mexico, the West Indies, Central America and South America.
Euphorbia hypericifolia is a low growing clumping shrub with oval leaves and masses of tiny white flowers. However, close inspection shows the pairs of white petals to be bracts and the actual flowers to be very small, inconsequential and Euphorbia-like.
Low growing, spreading habit. This area was under trees and in significant shade.
