Germander Speedwell is a low-growing, native plant with bright blue flowers and a soft, creeping growth habit. It occurs naturally in flower-rich grasslands, light woodland edges and herb-rich verges. Thanks to its early bloom and dense ground cover, Germander Speedwell is not only a subtle showstopper but also a valuable species for insect-friendly vegetation on lean soil.
What are the characteristics of Germander Speedwell?

How do I sow Germander Speedwell?
Sow about 1 gram per m² (± 4,500 seeds) in an open, sunny to semi-shaded spot. Germander Speedwell grows well on neutral to slightly calcareous soils, preferably dry to slightly moist and nutrient-poor. Sow directly at the final location. Press seeds lightly and cover with a thin layer of soil (± 0.5 cm) to prevent drying out.
The best sowing time is autumn (August–October). The seeds then undergo a natural cold period. With autumn sowing the seedlings often only appear in spring. Spring sowing (March–May) is also possible, but generally leads to a slower and less even germination process. In both cases allow several weeks to months for visible emergence.
How do I maintain Germander Speedwell?
Germander Speedwell is a low-growing, perennial species that requires little maintenance. It likes a light, open vegetation on nutrient-poor soil. Fertilisation is not necessary, and even undesirable in ecological management.
Mow one to two times per year. The first cut can be from the end of June, once flowering has finished and seed has fallen. A second cut in September or October is only useful when grass or dominant species start to take over. Remove mowings to keep light and space for low-growing species.
