Speedwell

Flowers April to June

Though there are perhaps two dozen or more varieties of speedwell you are only likely to have Germander and Slender Speedwell in the lawn with the latter being a garden escapee; lovely!

Germander Speedwell


Bright blue flower with a white eye, also known as Bird’s-eye Speedwell. Leaves have jagged or toothed edges. Becomes low growing and dense when in the lawn compared to a lanky growth habit in the borders.

Slender Speedwell

Tiny pink or mauve flower, also known as Round-leaved Speedwell. Has a similar growth habit to Germander Speedwell.

These plants spread from cuttings so most occurrences in the lawn are due to mulch mowing, raking, scarifying or mowing in general where some plant material is left behind. Therefore, removing all mowings and any plants from the borders is a very good idea.


  • Present all year round in the lawn
  • Very resistant to weed killers though you may have some success with Resolva Ready to Use
  • Can be checked with ferrous sulphate in spring but is unlikely to die
  • Can be controlled by frequent raking or scarifying but collect ALL the debris
  • Digging the plant out is the only sure way of removing it
