Care Guide
Planting
Plant your bristly jewelflower in full sun where it will get at least 6 hours of direct light daily. This California native thrives in the dry, well-draining conditions of grassland, chaparral, and woodland habitats, so choose a spot with excellent drainage and avoid areas that stay wet. Since it's an annual herb, you can plant it in spring to establish before summer heat arrives.
After Planting
Water regularly during your plant's first growing season to help it establish, then gradually reduce watering as it matures - it's adapted to California's dry conditions and won't need supplemental water once established. This is a low-maintenance plant rated moderate for ease of care, and it's fully deer resistant, so you can relax on that front. The biggest mistake people make is overwatering; remember this plant evolved in chaparral and grasslands where moisture is scarce, so err on the dry side rather than the wet side.
