Mineral Wildflower Festival

Technical Name

• Lysimachia latifolia (formerly widely known as Trientalis latifolia)

Informal Names

• Pacific starflower

• Broadleaf starflower

• Western starflower

Key Characteristics

• The Star-Shaped Flowers: Features small, delicate, star-shaped flowers measuring about 0.5 inches across. They range from pure white to a soft, pale pink and seem to "hover" gracefully on incredibly thin, thread-like stalks (pedicels).

• The Leaf Whorl: The foliage is unmistakable. A single, smooth, slender stem rises up and terminates in a neat, geometric whorl of 5 to 8 crisp green, egg-shaped (ovate) leaves. The flowers erupt directly from the center of this ring.

• Growth Habit: A low-growing, delicate perennial herb arising from tiny tuberous rhizomes, usually reaching only 4 to 8 inches in height.

Notable Significance

• The Primrose Connection: Though it looks like a miniature wood anemone, it actually belongs to the primrose family (Primulaceae).

• Mycorrhizal Networker: It relies heavily on healthy, undisturbed forest soil dynamics. It forms strong mutualistic bonds with underground fungal networks (mycorrhizae) to exchange nutrients beneath the dense forest floor layer.

• Ant-Dispersed Seeds: Once the flowers fade, they produce tiny capsule fruits containing seeds coated in a sweet, nutrient-rich structure called an elaiosome. Native ants eagerly collect the seeds, carry them back to their nests, eat the treat, and effectively plant the seeds in perfect underground conditions.

Locations Found

• Habitat: A true woodland specialist that avoids baking sun. It thrives in the deep shade or dappled light of moist, open coniferous forests, mixed woodlands, and damp, shaded rocky banks.

• Geographic Context: Native to western North America from British Columbia down through California. It is a classic understory companion beneath Ponderosa pines, Douglas firs, and white firs throughout the Sierra Nevada and Cascade foothills, making the pine-needle-strewn floor of Mineral an ideal home.
