A low-growing perennial wildflower with spotted red and yellow tubular flowers that bloom prolifically in moist, shaded conditions. Native to seepage areas and wet meadows, it thrives in cool, consistently moist soil.

Why grow it

Seep monkeyflower offers reliable color in wet, shaded microclimates where many ornamental perennials struggle. Unlike some moisture-loving species, it establishes readily from seed and requires minimal intervention once established in appropriate conditions. It provides a native alternative to exotic shade-loving flowers in regions where it occurs naturally.

Watch out for

This plant performs poorly in dry or well-drained soil and tends to decline if watering becomes inconsistent during the growing season. In garden settings, it may self-seed prolifically in ideal conditions, which some gardeners find valuable while others may need to thin seedlings to maintain desired spacing.
