Euphorbia exigua aka Dwarf Spurge

Euphorbia exigua, also known as dwarf spurge or small spurge, is a species of Euphorbia in the spurge family (Euphorbiaceae). It is native to Europe, northern Africa, and the Near East but has become invasive worldwide. In Finland, the only original spurge is marsh spurge, but several similar-sized species and small annual species have settled in. Dwarf spurge can be found in rural and urban flowerbeds, allotments, and occasionally in the wild. The plant's scientific name comes from its use as medicine in ancient times in northern Africa, named in honor of the knowledgeable physician Euphorbius. To control dwarf spurge, plants should be hand-pulled or mechanically controlled before flowering, and uprooted or buried to prevent resprouting at the soil surface. Specific chemical control recommendations are not included due to variable regulations around pesticide registration. Dwarf spurge is also a rare houseplant that thrives with very little water and prefers long-lasting, direct light less than a foot from a window. It likes soil that is extremely well-draining and does not need added fertilizers if repotted each time it doubles in size.
