The scientific name of Speedwell is Veronica
longifolia.  It's a very old plant and the first record
of its cultivation was in Switzerland and France in
the mid-1500's.  The flower itself is primarily blue
and grows cone-shaped sitting above heart-shaped leaves.  It must be carefully cared for, otherwise it
has the tendency to dry out and become limp. 
There are some pink and white varieties grown in Virginia.  These flowers have the same tendency
to dry out and must be carefully pre-treated.

Speedwell is available only in the heat of the
summer.  The flower is primarily used in mixed
bouquets and basic floral arrangements.  The Veronica longifolia has a limited vase life of about 5 days.
