Varieties

• Choose a clematis variety that doesn't need pruning, such as Clematis Sweet Autumn, C. montana Rubens or C. montana Tetrarose. Most clematis vines are pruned to 2 feet tall each year, and pruning would be difficult to do if the two vines were intertwined.
  
  

Evergreen Options

• Vigorous evergreen clematis (C. armandii) needs no pruning, except to keep it from overtaking the honeysuckle. Evergreen honeysuckle varieties include Lonicera henryi, L. heckrottii and L. sempervirens.
  
  

Conditions

• Both honeysuckle and clematis need full sun and regular water. Clematis needs more fertilizer than honeysuckle to bloom well. If the two vines become tightly entwined, their leaves will shade each other and cause leaf drop, so pruning may be necessary to admit more sunlight.
