This is Ribes aureum var. gracillimum, also known as Golden Currant. This shrub lives in full sun to partial shade. Growing to 6 feet high, the fragrant yellow flowers bloom in the middle of the Spring and attract a wide variety of birds, bees, and butterflies. Hummingbirds love these plants and the deer do not particularly like them. The flowers turn from the initial yellow color to orange and then to red. Ribes in general are larval host plants for Oreas Comma, Tailed Copper, Hoary Comma, and Gray Comma, butterflies, and the Ceanothus silkmoth, Clematis Clearwing, Small Magpie, Rocky Mountain agapema, Nuttalls sheepmoth, Western sheepmoth, Neoterpes trianguliferata, Formosa Carpet, Tetracis hirsutaria, and Io moths. It is also a nectar source for the Clarks sphinx moth. USDA Hardiness Zones 5 to 8.
