Rainy Side Notes

Veronica gentianoides is a charming mat-forming perennial with pale blue flowers and darker blue veining. In its nativity, this speedwell grows in mountain meadows and open woods. The genus is reportedly named after St. Veronica. Its epithet, gentianoides, means gentian-like, since the leaves resemble gentian leaves.

Gentian speedwell adds a delicate aspect to the garden and is suitable for the front of the border or planted in drifts. Since speedwell is easy to start from seed, sow enough for a large drift. The small perennials bloom in their second season, and by season three, their presence is well established in the garden. The little plants aren’t drought tolerant, so when our annual dry season rolls around, water them regularly.
