Large-flowered agoseris is found on thin-soiled upland prairies and rocky balds. It has a large rosette of cut-leaves and dandelion-type flowers that close by mid-morning. The flowers become a big white ball of fluff when in seed. As with our lawn dandelion, it will re-flower after it is cut. 1-2 ft.
Gorgeous sunflower! Multiple flowering stems provide spring blossoms. Found in upland prairies and rocky bald with our native Oregon White Oak. 2-3 ft tall. The seeds are a favorite of goldfinches returning from migration.
Eriophyllum lanatum var. leucophyllum (Oregon Sunshine)
Provides a very long-lived showing of golden daisies to the mid-spring and summer landscape. The wooly leaves form a dense, nearly evergreen mat 1-2' tall. It is excellent as a border perennial or a groundcover and is one of the matrix species in the Willamette Valley prairies. Nectar species for Fenders Blue Butterfly and Field Cresent.
The pale ivory flowers with elegantly recurved tips occur on tall stems. Showy mottled leaves. Plant deeply and grow in sun or shade. They will go dormant early in the season, so it is a great plant to mix into groundcover plantings.
Bright yellow rosaceous flowers clustered in upper leaf axils, compound lobed leaves, 2-3 ft tall when in flower. Does very well in a garden setting often blooming again after deadheading. Native to wetlands, streambanks and woodland edges..
With dark green finely dissected leaves, this biscuitroot produces new growth in the fall and blooms in May with a seemingly never-ending supply of brilliant gold-yellow flowers. It produces an outstandingly beautiful show. It is drought resistant.
This low-growing pea has striking yellow flowers with white tips and is an integral part of our wet prairies. It is found mostly in vernal wet areas with other perennials such as Allium amplectens and Triteleia hyacinthina, and Dodecatheon pulchellum and annuals such as Plagiobothrys figuratus, and Mimulus guttatus.
Potentilla gracilis (Slender or Graceful Cinquefoil)
Just as the common name says, this plant produces a graceful 1' mound of lacy fretted palmate foliage with sunshine yellow flowers. In western Oregon, it is a key species in both our wet and dry prairies and its long bloom-time in June attracts numerous native pollinators.
This native buttercup blooms April through mid-May and is an early shining star of our prairies. Very persistent due to self-sowing. It also makes a nice addition to native gardens giving our native bees important resources early in the season.
This small-flowered native buttercup is known by the common names woodland buttercup and little buttercup. It is native to many parts of the west where it grows in wet prairies or wet, wooded habitat such as oak/ash woodland and forested streambanks. It often grows as a biennial.
Solidago lepida var. salebrosa (Western Goldenrod)
For both wildlife gardens and restorations, Western goldenroad provides late-summer sprays of yellow flowers with soft foliage that are important resources for butterflies and bees. It is rhizomatous often forming colonies so makes a good bedding plant (rhizomatous), 2-3 ft tall. Provides nectar for Black Hairstreak butterflies along willow riparian areas.
This early-blooming species has deep yellow flowers and soft, fuzzy leaves. In a wildlife garden, the long-bloom period makes it a great bedding plant. It grows in moist to dry open woodlands and prairie where it attracts a variety of early pollinators. It does best on upland restoration sites where competition from invasive plants and grassy thatch are kept to a minimum. 8-10 inches tall.
Very showy, large yellow flowers (sunflower family), large expressive leaves (aka "mule's ears"). The seeds are large and attract goldfinches at the height of summer. Nectar species for Field Cresent butterflies.
