Veronica Prostrata
Prostrate Speedwell; Nat. Ord. Scrophulariaceæ.
This is sometimes confounded with V. repens, I presume from the slight distinction in the specific names, but so different are the two species that no one who has seen them can possibly take one for the other. V. repens is herb-like; it creeps and roots, and has nearly white flowers in April; but V. prostrata is a deciduous trailer, and the more common and best form has fine gentian-blue flowers; it is a capital rock plant, being most effective when hanging over the face of large stones. The flowers are small, and produced in rather long sprays, which are numerous, so that little else than flowers can be seen for two or three weeks.
It will grow and flower freely in any soil, but the aspect should be sunny; it is easily increased by division or rootlets. I may add that the very long stems of this prostrate plant (when in bloom) are well adapted for indoor decoration. Where pendent, deep blue flowers are needed, there are very few good blues so suitable.
Flowering period, May to July.
