Austrian Speedwell (Veronica austriaca) - Description
Veronica austriaca (syn. V. teucrium) ('Austrian speedwell', 'Saw-leaved speedwell') is a species of flowering plant in the family Plantaginaceae, native to northern temperate Europe. Growing to 90 cm (35 in)tall by 60 cm (24 in) broad, it is a mound-forming herbaceous perennial, with deeply toothed leaves and erect spikes of bright blue flowers throughout summer. The specific epithet austriaca refers to Austria within its native range. Several cultivars are available, of which the following have gained the Royal Horticultural Society's Award of Garden Merit:-
Austrian Speedwell (Veronica austriaca) - Blooming
Inflorescences of small flowers come in a variety of colors including white, rose, pink or blue.
Austrian Speedwell (Veronica austriaca) - Growth
Annuals, perennials (some are marginally aquatic), and deciduous subshrubs. Some of the subshrubs are rhizomatous. Most species of Speedwell do well with full sun with a few exceptions (V. repens tolerates shade). Veronica works well in a mixed or herbaceous border. Mat-forming species are good for a rock garden. Less hardy plants can be grown in a trough or alpine house.
Austrian Speedwell (Veronica austriaca) - Planting
Propagate from the seed in fall. Sow in containers in a cold frame (for protection and to ensure hardiness). Can also propagate perennials by division in fall or spring. For subshrubs, take softwood cuttings in spring. V. beccabunga should be propagated by division, or from semi-ripe cuttings in summer.
Austrian Speedwell (Veronica austriaca) - Pest
Scale insects. Other issues include powdery mildew, rust, leaf smut, root rot, and downy mildew.
Austrian Speedwell (Veronica austriaca) - Soil and irrigation
Watering needs are dependent on species or variety being grown. Rock garden and alpine species prefer poor to moderately rich soil with good drainage. Border veronicas do best in loamy soil, well-draining yet moist. V. beccabunga should be grown in wet soil or in water 5" deep.
