I have grown this plant for 8 years and I would not want to be without it. The gentian speedwell, is a very delicate looking plant that flowers in late spring, putting on a great floral display for about two weeks—which is too short. Even with such a short flowering season it deserves a place in your garden.
Veronica gentianoides grows in full sun, but also does well in part shade. In my garden it grows on the north side of the house and spreads slowly with above ground rhizomes. If it is left to set seed it will self-sow. I cut mine back after flowering and in part shade at least, it does not bloom again.
There is a herbarium speciman of Veronica gentianoides v. alpinia, which looks as if it blooms at under 10 cm. I could not find any references to living plant material but I do now have seedlings of this plant. It should be a stunning little rock garden plant.
