A stoloniferous perennial herb of woods, hedge banks, grassland, rock outcrops, upland screes, road verges, railway banks and waste ground, found on most soil types except the most impoverished. It also occurs on anthills on chalk downland.
It spreads vegetatively by prostrate stems which root at the nodes; reproduction from seed appears to be comparatively rare. 0-750 m (Meal na Teanga, Loch Lochy, Westerness), with an unlocalised record of 820 m elsewhere in the Scottish Highlands.
This plant is useful.
How to get rid of:
Use the gel (Roundup Gel) or ready-to-use spray (e.g Roundup Fast Action Ready-to-Use, SBM Job done General Purpose Weedkiller, Doff Glyphosate Weedkiller Ready-to-Use) on patches of speedwell. Leave the weed for three to four weeks for the weedkiller to take effect, before removing dead foliage.
