Care Guide
Planting
Plant your Texas Indian Paintbrush in full sun with fast-draining soil - this is non-negotiable, as it's a desert native that rots in wet conditions. The best planting season is fall or winter to establish roots before the dry season. Space it among or near small shrubs like chamise, golden yarrow, or sagebrush, since this plant is semi-parasitic and performs better with host plants nearby. Avoid rich, amended soil; lean, rocky conditions are what it evolved for.
After Planting
Water weekly during your first summer to establish roots, then cut back to once monthly or less once established - after that, rely on rainfall. The #1 mistake Bay Area gardeners make is overwatering out of kindness; this plant wants neglect, not care. Expect it to go dormant or decline in appearance during summer heat, which is completely normal. Don't prune unless you need to remove dead wood; this woolly wildflower looks best left to its own devices.
