Golden currant (Ribes aureum), also called buffalo currant, is a broadleaf deciduous shrub in the Grossulariaceae family native to western North America from British Columbia east to Saskatchewan, south to Texas and west to California. It reaches 6-8 ft tall (10 ft at 20 years) with a decumbent, thicket-forming habit. Fragrant yellow tubular flowers turn orange and red with age, appearing on previous season's wood.
Golden currant is hardy in zones 3a-8b and tolerates full sun to shade with wet-tolerant drainage (pH 4.7-7.8) and moderate water, requiring a minimum 12-inch root depth. Growth is fast with five diseases documented. The plant naturally occurs by streams and ravines.
