This dear little speedwell is a variable plant, sometimes downy and sometimes smooth; but with enough clearly defined traits to make it always recognisable.
In olden times its leaves were made into a popular beverage, something like tea, and for which it is said to have been a very good and wholesome substitute.
V. serpyllifolia, thyme-leaved speedwell, is another variety that is fond of the roadsides. The corolla is very pale, striped with a darker blue, and the leaves are more rounded in outline than those of V. officinalis.
