VERONICA GENTIANOIDES 'TISSINGTON WHITE'

What a fantastic plant Veronica gentianoides (also known as speedwell) are!  I first planted a veronica with pale blue flowers over ten years ago in my garden and it is still going strong, making a fine display every spring (May June) just about the time that many spring flowers from bulbs and corms are past their best. This year I introduced the Tissington White variety which, in truth, is not much whiter than the pale blue one but I am happy to have any variety of this plant in my garden. 

Veronica gentianoides Tissington White

Veronica gentianoides is as hardy as they come -  which no doubt is the reason I still have it after ten years - is easily divided and pretty unpicky.  The RHS says it prefers loam and moist but well drained soil of any PH, apparently. It likes full sun or partial shade.
They are excellent for the front of a border because the spikes (about 40-50cm tall) grow from a low mat which is easily divided.
