Botanical Name
Veronica austriaca ssp. teucrium 'Royal Blue'
Plant Common Name
Broadleaved Speedwell, Royal Blue Speedwell
General Description
Offering a much sought-after color for the garden, the gorgeous flowers of Veronica austraica subsp. teucrium ‘Royal Blue’ are intense, violet-blue. The small but vivid blooms are held in short, open spikes, and appear in late spring atop low-growing mounds of small, dark green, toothed foliage.
Thriving in full sun and reasonably rich, well-drained soil, Veronica ‘Royal Blue’ is somewhat tolerant of drought, but performs best with regular moisture. It may be cut back to the ground in early summer to maintain a neat look and to encourage a flush of fresh, new foliage. ‘Royal Blue’ looks amazing when combined with the spicy, soft pink blooms of Dianthus ‘Bath’s Pink’ and the starry, electric-yellow flowers of Allium moly ‘Jeannine’.
The genus Veronica encompasses a large number of annuals, perennials and sub-shrubs, most of which are native to Europe. Veronica species may be prostrate or upright, and occur in a variety of habitats ranging from moist meadows to dry, rocky alpine areas. Small, narrow to open, lobed, tubular flowers in shades of blue, purple, white or pink are held either singly or in dense to loose, upright spikes. The many forms of Veronica have yielded numerous excellent, garden-worthy cultivars and hybrids.
