25 Orange Paintbrush Seeds Castilleja Wildflower Heirloom Garden Planting

Castilleja species, commonly called Indian Paintbrush, is a striking wildflower known for its vivid orange-red bracts that bring a bold, natural look to meadows, borders, and pollinator-friendly landscapes. This heirloom selection is valued for its bright color and its ability to add a wild, prairie-inspired character to garden plantings.
