[Its exact product profile](https://plantsofthewild.com/product/native-roots-penstemon-cardinalis-cardinal-beardtongue-3-5-pot/) supplies the selection-specific size and bloom details. ## Garden Use Use this western native in a sunny border, rock garden, or water-conserving planting. The glossy green leaves form a low basal mat, while flowering stems rise above it. The species profile from [Western Native Plants](https://cwelwnp.usu.edu/westernnativeplants/plantlist_view.php?id=38&name=penstemoncardinalis) describes the cardinal penstemon as native to New Mexico and west Texas and suitable for beds, berms, and rocky gardens. ## Growing Conditions Provide full sun for best flowering, though the species tolerates some part shade. Choose well-drained soil; the plant profile recommends a calcareous, nutrient-poor site and cautions that heavy soil can encourage root rot. Supplemental irrigation is helpful during the driest part of summer. ## Maintenance Water while establishing and periodically through the driest summer weather. After flowering, remove spent stems to improve appearance and encourage fresh leaf growth. Keep fertilizer light; the species profile notes that minimal fertilization is needed.
