金絲桃 St. John's wort ( Hypericum x moserianum ' Tricolor ' )

This shrub is semi-evergreen, so it can lose some of its leaves in winter. Arching red branches are cloaked with variegated cream, pink and green foliage that makes a colourful addition to the front of borders. It grows equally well in sun and shade, but needs protection from cold, drying winds.
