use
Wagner's Oregon grape is rarely used as an ornamental shrub in gardens and parks; different types are known:
- 'Moseri' has pale green, pink to red tinged leaves
- 'Pinnacle' is up to 1.5 meters high and is characterized by dull bluish gray-green leaves, bronze-colored when shoots; numerous pure yellow flowers. This variety is also known as Mahonia 'Pinnacle', as Mahonia aquifolium 'Fascicularis' or as Mahonia pinnata ( Mahonia pinnata is the correct botanical name for the leaved Oregon grape ).
- 'Undulata' with glossy dark green leaves that are wavy on the edge and turn red-purple in winter.
- 'Vikaryi' has similar characteristics to the variety 'Pinnacle' and sometimes turns red in autumn.
