Polemonium pulcherrimum var. pulcherrimum (Sky pilot) is a native California herb in the Polemoniaceae family, recognized by blue/purple flowers in cushion form.
Sky pilot is a California native perennial found in the Klamath Ranges, northern Coast Ranges, high Cascade Range, northern and central Sierra Nevada Mountains, Modoc Plateau, and northern Sierra Nevada at elevations of 2,400 to 3,700 meters in rocky talus habitats. Flowering from June to September, this plant produces striking blue to purple flowers in delicate clusters. Growing with compact stems typically 10 to 20 centimeters tall, it forms dense, low-growing cushions in alpine and subalpine environments. Its leaves are finely divided with numerous small leaflets, creating a dense, feathery appearance characteristic of high-altitude mountain plants. The plant's sparsely glandular-hairy foliage helps it survive in harsh, exposed mountain landscapes.

How to tell it apart
vs Phlox: Polemonium (Jacob's ladder) has pinnately compound leaves with many discrete leaflets arranged ladder-like along the rachis; Phlox has simple, entire, usually opposite leaves.; vs Gilia: Polemonium bears true separate leaflets; Gilia leaves are pinnately dissected into narrow lobes rather than divided into distinct leaflets.; vs Ipomopsis: Polemonium leaflets are broad and entire; Ipomopsis leaves are finely cut into thread-like segments.; vs Collomia: Polemonium has compound leaves and open branched cymes; Collomia has entire to lobed leaves and flowers clustered among leafy bracts.; vs Vicia: Polemonium leaves lack tendrils and its flowers are radially symmetric bells or funnels; vetch leaves end in tendrils and bear bilateral pea flowers.
