Scarlet bugler (Penstemon centranthifolius) is a striking perennial herb in the plantain family (Plantaginaceae), known for its bright red to orange-red tubular flowers that are irresistible to hummingbirds. Native to California, it grows widely across northern, southern, and central regions.

This drought-adapted plant thrives in rocky, well-drained soils, making it a perfect addition to rock gardens, slopes, and pathways. It requires little supplemental water once established and blooms profusely in the spring. The upright, slender stems can reach over a meter in height, with thick, smooth leaves arranged in pairs along the stem.

Beyond hummingbirds, scarlet bugler also attracts bees and butterflies, contributing to a vibrant and pollinator-friendly garden. Its vivid flowers and minimal water needs make it an excellent choice for low-maintenance native plant landscapes.
