Care Guide

Planting

Plant Mexican Rush in partial shade in a location where soil stays consistently moist or even wet - this plant thrives in boggy conditions and can tolerate standing water. It grows in any soil type as long as adequate moisture is present, so don't worry about amending for drainage; instead, choose a spot that naturally stays damp, such as near a rain garden, pond edge, or low area that collects water. Plant in spring before the growing season begins. Space plants according to their mature size, which ranges from 1 to 2.5 feet tall depending on growing conditions.

After Planting

Water consistently to keep soil moist throughout the growing season and especially during summer - this is the #1 requirement for success, as Mexican Rush is adapted to saturated conditions and will struggle if allowed to dry out. Expect flowers to appear in spring (March–May). The plant is deciduous and will die back in winter; leave the dried stems standing for structure and wildlife habitat until early spring, then cut them down before new growth emerges. Once established, Mexican Rush requires minimal intervention beyond maintaining consistent moisture; it tolerates cold to 15°F, so it will reliably return each year in the Bay Area.
