Noteworthy Characteristics

Veronica gentianoides, commonly called gentian speedwell, is a mat-forming perennial which typically forms basal foliage clumps (rosettes) of broad, oblong-lanceolate, glossy dark green, basal leaves (to 3" long). Foliage clumps slowly spread in the garden over time by creeping roots to form dense mats. Flowering stems rise from the rosettes to 20" tall and are topped with 8-10" long, loose, terminal racemes of blue flowers (1/2 to 3/4" wide) in late spring to early summer.

Genus name honors Saint Veronica who reportedly gave a handkerchief to Jesus so he could wipe sweat from his face on the way to Calvary, with some genus plants having markings that resemble the markings on the sacred handkerchief.

Specific epithet means similar to gentian (Gentiana).

'Alba' is a white-flowered cultivar of the species.
