Product Description
Low mounds of chartreuse-yellow leaves with contrasting blue flowers in early summer; also known as Veronica austriaca trehane.
0.5' tall x 1-1.5' wide prostrate clumps, very slowly spreading wide. Flowers in May/June. The chartreuse color is the richest in the spring and fades to yellow/light green with summer heat.
Forms groundcovering clump, but it is not very competitive plant (originally meadow plant) and can't suppress weeds (seedlings of any other plant can establish in the clump of this speedwell).
Sun, half-sun to half shade, in hotter climates is better spot with some shade during the day (especially afternoon shade), because the leaves are more sensitive than regular green-leaved variety.
Average soils with average moisture, somewhat drained (don't plant in waterlogged soils).
Hardy in zones 4 to 8. Deer and rabbit resistant. Black walnut tolerant.
Best for the front or edge of flower bed, rock garden, crevice gardens, bigger trough or bigger container. Trouble free plant, may need to be cut back after flowering (for better and fresh leaves).
Can be combined with many common perennials. But looks very well with blue, or blue-purple flowers of shorter cultivars of : Amsonia, Agastache, Aster (novae-angliae 'Purple Dome' for example), Calamintha nepeta 'Blue Cloud', Baptisia, Dracocephallum, Geranium, :avandula, Kalimeris 'Blue Star' , Iris x barbata 'Nana' and 'Media', Paeonia, Penstemon, Polemonium (in half shade), Salvia nemorosa hybrids, Ruellia humilis, Scabiosa columbaria, Scutellaria ovata, Sisyrinchium, Stokesia, Tradescantia (half-shade) or Stachys 'Hummelo'.
