Speedwell is considered an agricultural weed - though how much harm it really does to crop yield is questionable. It's main impact is that if it is growing densely in the base of cereal crop, its tangled juicy green stems can make the crop difficult to cut mechanically.

Its tiny, simple blue flowers are familiar to almost anyone, and it's easy to see how it gets its country name of "bird's-eye". 

It's hard to believe this garden flower, with its complex, multi-floret structure, is from the same genus. Nevertheless, they are both species of Veronica, and indeed both called 'speedwell', though this one is 'longleaf' speedwell. Gardners commonly just call it 'Veronica'.
