About
Clematis 'Corona' is a compact, deciduous climber that reaches a height of up to 2 meters. It features mid-green foliage and produces numerous single, velvety crimson blooms measuring up to 16 centimeters in diameter. Each flower showcases a darker central bar and is adorned with stamens that have white filaments and dark red anthers. The flowering period extends from late spring to early summer, during which some blooms may appear semi-double. In late summer, the flowers tend to be smaller and lighter in color.
