A showy native of the Caucasus, rather aggressively escaping from cultivation to lawns and unmowed grass. First collected in Michigan in 1978 in Kalamazoo and Washtenaw Cos., but doubtless established somewhat earlier.
The attractive blue flowers are 6.5–12.5 mm wide and on their elongate pedicels stand out above the creeping stems with their small leaves (blades less than 1 cm long). Fruit has never been seen in Michigan, and is rarely, if ever, to be found in North America, so spread is presumably entirely vegetative.
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.
