Care Guide
Planting
Plant Toad Rush in full sun in a location that stays consistently moist - this plant thrives in muddy, wet spots where other plants struggle. It's tolerant of various soil types (fast, medium, or slow drainage) as long as moisture is available, making it ideal for boggy areas or low spots in your Bay Area garden. Plant in spring for best establishment, spacing plants about 12 inches apart.
After Planting
Keep the soil moist throughout summer and don't let it dry out completely; this is the #1 mistake people make with Toad Rush, since it's adapted to wetland conditions. Toad Rush is an annual that flowers from September through March, so expect it to complete its life cycle within a year - treat it as seasonal color rather than a permanent fixture. Once established, it requires minimal maintenance beyond consistent moisture, and it will tolerate Bay Area cold snaps down to -10°F with no special protection.
