‘Purple Showers’ viola is touted for its large, dark purple flowers that appear from spring through fall atop compact foliage. Lightly fragrant, deep purple-violet flowers appear in spring and then sporadically throughout the season, providing a soft show of color. The flowers fade to lavender. Although flowering in one trial garden (full sun and well-drained soil) was prolific, the May flowering was sporadic in the other gardens.
Veronica ‘Purpleicious’ is an erect, bushy, clump-forming spike speedwell that is noted for its long period of bloom. Flowers were given high marks for repeat bloom. Evaluators characterized its flower color as a purple-pink, jewel-toned violet and rich pink-violet. Peak bloom took place in June-July, but some flowers were still present in September.
Eveline speedwell blooms mid to late summer with some re-bloom in September. The flowers are pink-purple on a tapering four-inch spike. Repeat bloom is more consistent when spent flowers are deadheaded. Dark green, disease-resistant foliage stays shiny and clean late into the season. There is no significant fall color.
