The Keys wedge spurge (Euphorbia deltoidea ssp. serpyllum) is historically only known from pine rockland habitat on the island of Big Pine Key in the lower Florida Keys and it was federally listed as endangered in 2016. In 2019, in an effort to safeguard this species, Fairchild Tropical Botanic Garden Conservation introduced seeds to the neighboring island of No Name Key, where recent pine rockland restoration efforts improved habitat for rare plant translocations of this species and others (Big Pine partridge pea, sand flax). In this photo one month after seed introduction, there are 2 seedlings of the Keys wedge spurge, one set of cotyledons with its seed coat still attached!
