'Sunny Border Blue' Speedwell
Fuss-free and easy-growing, 'Sunny Border Blue' speedwell thrives with minimal care when tucked in average, well-drained soil. Blossom spikes contrast strikingly with the round flower form of roses. Speedwell buds appear in May and keep coming all season long if you faithfully remove spent blossom spikes. This perennial is hardy in Zones 5 to 9 and is gorgeous when planted with roses in shades of pink, red or yellow.
