Plant and Animal Species to Know In Willamette Valley Ecology

Bradshaw’s lomatium (Lomatium bradshawii) - This wildflower is very scarce, and in fact is only found in a few places in the whole Willamette Valley. It was removed from the Endangered Species List in 2021, but could be placed on it again given significant habitat destruction in SW Washington State. It is found on two Trust sites.
Willamette Valley Bittercress (Cardamine penduliflora) This sweet wildflower is an early arrival as well, and can be found just prior to the blooms of Common camas, and Bradshaw’s lomatium in April in the mid Willamette Valley.
Some Sweet Native Species to Know - Starting with Wildflowers! The general order is from the earliest blooms to the latest in the season.
Western Buttercup (Rannanculus occidentalis) This is a relatively common early blooming wildflower that can be found in meadow, and wet prairie habitat in the Willamette Valley.
Blue-eyed grass (Sisyrinchium idahoense) This gorgeous flower is generally found in single blooms, just a few inches above the ground typically intermixed in other grasses and flowers.
Slender leaf cinqufoil - (Potentilla gracilis) This native flower rises from groupings of leaves that have a serrated appearance. Their yellow flowers are gorgeous and they can spread across portions of fields in June and July.
Meadow checkerallow (Sidalcea campestris). This sweet flower appears in May and often into July and can be widespread in meadow habitat.
Common Camas (Camassia quamash) This amazing wildflower was a food staple for native people in the valley for millennia. It arrives in early to mid April, and blooms can be found in more shaded wet areas well into June. While it is not uncommon, most typically it can be seen in open meadow/wet prairie habitat.
