Overview

Omphalodes verna is a semi-evergreen, stoloniferous perennial reaching 4-8 inches (10-20 cm) tall with an indefinite spread and a low, mat-forming habit. Native to southern Europe (Italy, southeastern Alps, Balkans), this species spreads more vigorously than O. cappadocica by long surface stolons, forming extensive carpets. The basal leaves are 1.5-3 inches (4-8 cm) long, ovate to heart-shaped, medium green, with less prominent veining than O. cappadocica. Bright blue flowers with white eye, 0.2-0.4 inch (5-10 mm) across, appear in loose sprays in March-May. Growth rate is moderate to fast. Hardy to zone 5. The most vigorous and cold-hardy Omphalodes spp.—forms ground-covering mats more quickly than O. cappadocica. Can spread beyond intended bounds.

Native Range

Omphalodes verna is native to southern Europe—Italy, southeastern Alps, and the Balkans—in moist, shaded deciduous woodland floors.

Suggested Uses

Planted as a woodland groundcover under trees or in shaded areas at 12-18 inch (30-45 cm) spacing. The vigorous stoloniferous spread fills large areas more quickly than O. cappadocica. Can spread beyond intended bounds—use where expansion is acceptable or edge to contain. Requires shade and moisture. Not suitable for full sun, dry sites, or confined spaces where spread is problematic.

How to Identify

Distinguished from O. cappadocica by the smaller flowers (0.2-0.4 inch versus 0.3-0.5 inch), the more vigorous stoloniferous spread, the lighter green and less prominently veined leaves, and the lower overall height (4-8 inches versus 6-10 inches). Distinguished from Myosotis spp. by the perennial stoloniferous habit and the heart-shaped basal leaves. The fast-spreading low mat of heart-shaped leaves with small bright blue flowers is diagnostic—the most vigorous Omphalodes spp. groundcover.
