Navarretia sinistra (formerly Gilia sinistra) is a species of flowering plant in the phlox family known by the common name Alva Day's pincushionplant.[1]
Navarretia sinistra produces a branching, leafy stem coated in knobby glands. The leaves are sometimes deeply cut or lobed.
The inflorescence produces generally 2 or 3 flowers on very thin stalks. Each flower has a pouchlike calyx of sepals which are ribbed with reddish membranous tissue between. The tubular flower has a pink corolla and a red-streaked yellow throat. The protruding stamens are tipped with blue anthers.
The bloom period is June to August.[1]
The plant is endemic to the western United States, within northern California, Nevada, and Oregon.[2]
It is native to mountain chaparral, sagebrush scrub, yellow pine forest, red fir forest, and lodgepole forest habitats, often on volcanic or serpentine soils.[1] It grows at 50m-2700mm (160feet-8,900feetm) in elevation.
