do clematis need darkness at night? i have mine on the lamp post and it grows pretty well, but it does'nt seem to flower towards the top where the light source is. (i have it on a dusk to dawn sensor). Thanks

Plants have been known to grow differently under florescent lighting. For example, soybeans will grow twice as tall within 20 feet of a light as those distant from it. Clematis is not known to be limited by light at night. If your plant is healthy and blooming lower in the vine I would not worry about it as Clematis can be diseased prone and you are already ahead of the game with a healthy plant. If there are no blooms anywhere on the plant then you may want to find a location away from the light and transplant in the fall.
