Germander speedwell is originally native to Europe, Western Asia, and the Caucasus region. It has been introduced and naturalized in parts of Northern and Southern America, as well as in Oceania. This species is also cultivated in various regions beyond its native range for horticultural purposes.

Germander speedwell or Germander speedwell finds its original roots in Eurasia and is generally considered a broadleaf weed. As a weed, its survival potential is high as it is hardy, colonizing, and can proliferate in a variety of conditions. Moreover, its high reproduction rate, achieved through the large number of seeds it produces, can result in a widespread invasion of this plant, often dominating flower beds and out-competing other plants for nutrients and light. More so, it’s a perennial weed meaning it has a long lifespan and can regrow each year from root stocks. Recognizing germander speedwell in your garden requires vigilance, look out for its small bright blue flowers, heart-shaped leaves and creeping stems. The plant mainly disperses its seeds through the action of wind or animals, thereby spreading to new locations. This dispersal mechanism is adept at invading new territories, making this plant not just a persistent, but also a highly invasive weed.

For germander speedwell, the best time to control it is before it sets seed in late spring or early summer.
