A nettle-like but stingless white-flowered plant blooming from spring to autumn; though its nectar is deep, it gives bees early-season nectar and pollen.
It grows on nutrient-rich soils along woodland edges, at the foot of hedges and beside gardens and roads in Europe, northern Anatolia, the Caucasus and the temperate parts of Asia. The corolla tube of its flowers is about 10 mm long, so the nectar suits bumblebees better; honey bees benefit when the nectar level rises and in flowers with shorter tubes, and they also collect pollen.
It flowers from late April to September, most profusely in spring. Plenty of moisture and mild weather increase secretion; in dry summer months flowering weakens.
There is no monofloral honey. In spring it makes a small but regular contribution to mixed spring honeys and pollen stores.
It is often cleared away because it is mistaken for nettles; leaving it along hedges and garden edges creates a valuable food strip for bumblebee queens and bees early in the season. It spreads by itself and needs no care.
