Pennell's speedwell is a adaptable perennial that thrives along stream banks, pond margins, and in moist garden borders with full sun to partial shade. Keep the soil consistently moist and provide good light for the best display of its small blue-pink flower spikes in summer. It is low-maintenance once sited correctly and provides attractive foliage alongside seasonal bloom interest.
