Care Guide

Planting

Plant your red-flowering buckwheat in full sun in a location with good drainage - it tolerates clay and even saline soil well, so you have flexibility here. The best time to plant is in fall or early spring. Space plants about 1–2 feet apart since they're mat-forming and spread slowly. If you're in a hotter inland Bay Area location, afternoon shade will help it thrive and reduce your watering needs.

After Planting

Water weekly during your first summer to establish the plant, then cut back to once weekly or less as it matures - established plants need only minimal water. Once established (typically by year two), you can go weeks without watering. Expect blooms from June through November. The #1 mistake is overwatering: this is a drought-tolerant native that will rot in soggy soil, so err on the side of dry.
