Tidal Pool Prostrate Speedwell

Veronica 'Tidal Pool' PPAF



This hybrid prostrate speedwell was selected from a cross made at the Chicago Botanic Garden in 2007 between Veronica armena and Veronica pectinata ‘Rosea’, two already popular prostrate speedwells. This selection seems to have inherited the best traits from both parents: it's denser and faster spreading than either parent, with small oaklike leaves that are medium green with a faint silvery-blue cast from its slight pubescence. The plants cover themselves with medium to deep blue-violet flowers from late April into mid-May. The rest of the growing season, they settle into attractive groundcovers that seem to handle cold, heat, humidity, rain, and drought equally well.

Trial plants at the Garden have been through two winters and three summers without any cultural issues. Two-year-old plants have grown to 2" tall by 22" wide on a clay soil, and to 3" tall x 30" wide on a sand soil. This selection can be propagated readily from cuttings or by division. For use in full sun as a groundcover, edging plant, in the rock garden, or cascading over rocks or walls. The plant will tolerate some light foot traffic. Dense enough to suppress some weed growth. May make a good bluegrass lawn substitute in dryland states. Well-drained soils recommended. Very drought tolerant.

Likely hardy to USDA Zones 4 to 8. Introduction #CG10-001. Developed by Dr. Jim Ault at Chicago Botanic Garden.
