Whitestem Frasera is a species of flowering plant in the gentian family also known by the common name Idaho Frasera. It is native to the northwestern United States, where it grows in open areas in mountain habitat. It is a perennial herb growing from a woody base surrounded by rosettes of leaves. The leaves are green with white margins. Each flower has a calyx of four pointed sepals and a corolla of four pointed lobes each 1/2-1 centimeter long. The corolla is pale greenish white to light blue to purple, often dotted, streaked, or veined with darker blue. There are four stamens tipped with large anthers and a central ovary.
Seeds of F. albicaulus were shown in one study to have deep morphophysiological dormancy, with long periods of cold stratification needed to finalize embryo growth and induce germination. 4-8 weeks of artificial cold stratification at 40°F averages a 50% germination rate. Seeds that were placed outdoors in November and naturally stratified had a germination rate of 33% in April with 6% more the following spring. Whitestem Frasera can be grown well in a mix of equal parts loam, sand, and leaf mold or compost.
