Ronica™ Blue Veronica longifolia

Ronica™ Blue is a compact, upright selection of Veronica longifolia with deep-blue flower spikes over fresh green leaves. Its tidy 14-inch height and 16-inch spread suit the front or middle of a sunny perennial border. ## Flowers and Placement The Danziger selection is listed at 35 cm tall and 40 cm wide, with USDA Zones 4–9 hardiness. It begins flowering in late spring; cutting back after the first flush can support a later display into fall. Use the flowers in borders, mixed containers, or cutting gardens. [Danziger lists the selection’s dimensions, upright habit, and zones](https://www.danzigeronline.com/catalog/perennials_catalog/ronica-blue/); [Perennials.com describes its blue spikes, flowering season, garden uses, and growing conditions](https://www.perennials.com/plants/veronica-ronica-blue.html). ## Growing Conditions Plant in full sun or partial shade in average to moist soil. Normal, sandy, or clay garden soils are listed as suitable. The species name and Ronica™ Blue trade name are retained together to keep the exact selection clear. ## Maintenance Remove faded flower spikes to encourage additional buds. If the first flush is cut back in midsummer, this selection may rebloom in fall. It is otherwise an easy-care perennial.
