 The color blue is highly valued in the ornamental landscape chiefly because of its rarity, there are so few plants with blue flowers. One genus that is able to supply this need in the garden is Veronica. A relatively large genus with over 500 species Veronica was formerly classified as being within the Scrophulariaceae family but has recently been reclassified to the plantain family or Plantaginaceae.
Phylogenetic research (DNA testing) has indicated that the formerly rich and diverse Scrophulariaceae be divested of the majority of its 275 genera (over 5000 species) leaving Scrophularia, Verbascum, Diascia and Buddleia as the most familiar of about 60 genera. Plantaginaceae, previously best known for the lowly Plantago or Plantain (the common weed of containers and gardens, not to be confused with the banana plantain) now shelters over 90 diverse genera the most recognizable of which are Antirrhinum, Bacopa, Chelone, Digitalis, Veronicastrum and of course Veronica. Rarely has anyone accused taxonomists of a desire to simplify any situation that comes to their attention.
The genus Veronica is itself extremely diverse with species originating worldwide but predominately in the northern hemisphere. Growth habits range from low, creeping groundcovers to upright stately specimens and everything in between. The common name of Speedwell is thought to originate from the Irish folk tradition of carrying a sprig of foliage as a protective charm while traveling - an appeal for speed and wellness.
Easy to grow in most garden situations, Veronica prefer full sun and can handle some shade but flowering is improved in higher light levels. Average garden soil is preferred, too rich an environment is liable to encourage soft growth unable to hold itself up. Most desire regular moisture but short periods of drought are tolerated as long as the plants are well established. The taller species hold their flowers on upright spikes in shades of blue, purple, pink or white. Veronica is attractive to butterflies and hummingbirds but not deer. Perfect for massing in borders or as specimens in containers. Veronica flowers are excellent for cutting and frequent deadheading will encourage repetitive blooming. Hardy to USDA 3 - 11.
Veronica ‘Baby Doll’ PP#16428A recently released beautiful petite cultivar. Selected for its dark green foliage which acts as a lovely background to the clear pink flowers. Masses of narrow spikes reach a height of 10” (25cm) on a dense bushy plant with a similar spread.

Known for having a consistent upright habit and crisp green foliage with violet flowers from May through the end of September. Height 20” (50cm). Spread 12” (30cm).
V. ‘Purpleicious’ PP# 17,639The product of a breeding program looking to create excellent cut flowers with a new range of vibrant colors the hybridizer has also produced a wonderful garden plant, as often, suitability for the cut flower market does not necessarily correlate to garden worthiness. ‘Purpleicious’ has deep purple flowers on tall spikes from late spring through early fall. As to be expected, the plant has strong study stems and glossy dark green foliage. Height 20” (50 cm). Spread of 14” (35cm).
