Plant Common Name

Darwin's Blue Speedwell, Spike Speedwell

General Description

This upright, heavy-blooming spike speedwell bears many violet-blue spikes of blooms in summer.

Spike speedwell is a long-blooming ornamental that is a staple for the sunny perennial border. This clump-forming plant has a more upright habit than others and originates from Europe and western Asia where is inhabits open grasslands, hills and woodsides.

The foliage is rich green and turns yellow-green in fall. In summer it bears dense upright spikes of many small violet-blue flowers. These are lightly fragrant, highly attractive to bees and butterflies and will continue blooming if regularly deadheaded.

This sun-loving perennial grows best in fertile to average soil with good drainage. It is a great plant for rock gardens, mixed borders and can even be used as a small-scale herbaceous groundcover. It pairs well with Dianthus, mounded wormwood and white catmint.
