About

Clematis 'Advent Bells' is a robust climber that can grow up to 5 meters in height. It produces distinctive, bell-shaped blooms with four petals that are a pale greenish-cream color, featuring dark red speckles on the interior. The long, greenish stamens add to its unique appearance. During the summer, the leaves may either turn a lime-green hue or drop off entirely as the plant enters its dormant phase.
