Triangle Orache is native to a wide region encompassing parts of Northern Africa, the Middle East, significant areas of Europe, and Central Asia. This plant has also spread to various continents, including South America, East Asia, and Australasia, illustrating its broad adaptability in both its native and introduced ranges.

Triangle Orache originates from Europe and Asia. This perennial plant is frequently considered a weed because of its highly competitive nature and adaptability to a variety of conditions, including urban environments, coastal areas, and agricultural fields. Its harmfulness lies in its ability to crowd out native and ornamental plant species, altering habitats and negatively affecting biodiversity. Moreover, with the capacity to produce up to 100,000 seeds per year, it demonstrates an alarming rate of reproduction. These seeds can survive in soil for several years, further fueling its wide distribution. Triangle Orache primarily spreads by dispersal of its tiny, wind-borne seeds, making containment efforts challenging.

The best season for removing triangle Orache is during spring and early summer, before it has a chance to flower and seed. Pay extra attention to the growth progress of the plant, the aim is to remove it when it's young and not yet mature.
