Tide Pool prostrate speedwell is a Chicagoland Grows® selection. Chicagoland Grows® is a plant introduction partnership of the Chicago Botanic Garden, the Morton Arboretum and the Ornamental Growers Association of Northern Illinois formed to promote plant cultivars that perform well in northern Illinois. This variety was developed at the Chicago Botanic Garden; it is a cross between Veronica armena and Veronica pectinata ‘Rosea’. Tide Pool speedwell 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.
