Short-spur Seablush (Plectritis brachystemon), sometimes classified as a subspecies of the common Seablush (Plectritic congesta), is a stunning annual wildflower native to the Pacific Northwest, thriving in moist meadows, open woodlands, and coastal prairies. This delicate plant produces an abundance of dense clusters of baby pink to white flowers that bloom atop slender stems. As an early-season bloomer, it is a vital nectar source for native pollinators. Short-spur Seablush is also a species of conservation concern in some areas due to habitat loss and listed as threatened in WA state, making it a meaningful addition to restoration and preservation projects.
Short-spur Seablush typically blooms in mid to late spring, creating vibrant displays that attract native bees, butterflies, and other beneficial insects. Its early blooms provide an essential food source for pollinators emerging from winter dormancy. The plant is also a key component of the ecosystem in its native range, supporting the biodiversity of grassland and coastal environments. While not a host plant for specific species, it plays an important ecological role by contributing to pollinator and plant community interactions. Additionally, as a species of conservation concern in parts of its range, planting Short-spur Seablush helps to support its survival and the health of the ecosystems it inhabits.
This wildflower thrives in a variety of soil types, including loamy, sandy, or gravelly soils, as long as they are well-drained. It prefers full sun to partial shade and grows best in areas with consistent moisture during its growing season. Seeds are easy to grow and require no pre-treatment; they can be sown directly onto the soil surface in the fall for natural germination over winter. As an annual, Short-spur Seablush self-seeds readily and is particularly suited to areas where native grasslands or coastal meadows are being restored.
