The flowers are small, bell-shaped, with 4 lanceolate curved sepals. The sepals are about 3.5 cm long and 1.6 cm wide at their widest point. Sepals are pink-cream on the outside and yellowish-cream on the inside with numerous red spots and spots. Stamens are long, with cream or greenish stamen filaments and reddish-pink anthers.


Clematis ‘Advent Bells’ care and pruning

Since ‘Advent Bells’, like other clematis of the Cirrhosa group, is a semi-evergreen, it has certain specifics. Firstly, it is quite heat-loving and cannot tolerate temperatures below -10 degrees Celsius (14ºF). Secondly, just because it can survive temperatures of -10 degrees Celsius does not mean that it can be successfully grown in regions where such temperatures are common.
The fact is that Clematis ‘Advent Bells’ is heat-loving. It needs a long period of high temperatures in order to bloom well enough to set a sufficient number of good flower buds. If it does not get enough heat, it will grow and increase its green mass, but will not bloom. This has been the experience of gardeners in New York and Oregon, as well as in some European countries with comparatively mild but still cold winters.
