Lianas are various climbers (arboreal or grassy) which have rather thin and weak stems. These plants are very decorative and can be used in vertical gardening. Lianas are useful plants because they create favorable microclimate (especially when they placed near the buildings walls to prevent its heating). Clematis is the most relevant plant which can be used in garden design. This liana described in separate section of our encyclopedia. However it’s necessary to remember that clematis is rather uncertain plant and can’t winter without a cover. Calystegia hederacea “Multiplex”is another popular plant with a fine winter hardiness. Calystegia is an appropriate liana for vertical gardening, for decoration of pergolas and balconies. The flowers remind tiny roses.
