Campaniflora was purchased as a small plant last spring and has yet to reach any size where I can give conclusive info on. The plant bloomed this spring for the first time and it was in bloom for maybe 3 weeks. It still has its lower leaves.

Huldine is probably a 3 week bloomer as well in my garden. It doesn't tend to rebloom in my garden on its own and I have yet to try cutting it back to get reblooms. It is interplanted with other clematis so it is hard to tell if its lower leaves are retained or if they fall off.

Just remember your experience in your garden with these clematis may be very different from what anyone tells you. Also, how close you plant the plants together in the first place may determine how large and how big a spread any may make. Surrounding plants that might compete with the plants for water and nutrients will also affect their eventual height and lower leaf coverage.

I grow Huldine. It is only 3 years old but it is becoming a large vine. Mine is about 12' tall by about 4'. It has been blooming for a long time 5-6 weeks. It has leaves all the way to the bottom. I planted one in a shady area and it did poorly and died. The second plant is in a sunny area(west exposure)and is doing very well. It's a very pretty one.

I don't have camplaniflora, but clematis on the web says it gets 10-20' tall, so it should be a good sized vine also. Were you going to plant them in the same area? Clematis can be planted fairly close together and grow thru each other. Minimum distance is about 2' apart when growing plants with the same pruning requirements. Contrasting colors I think look better than white on white, although your flower shapes are different which adds contrast. Here's a photo of Huldine.

Miguel, always grateful for your continual supply of planting suggestions. Fanflower, beautiful photo. Thanks for the info. I don't know why the catalogs dont's give widths. I do not plan to twine two whites together. I have a deck with 4 section. Each section will have a different white variety. At dusk white is awesome and glows in the dark. This will be my moon garden.

Robin, most nurseries don't give widths since the heights they give are estimates only since so much depends on your growing conditions, soil fertility, sun exposure, etc. Trying to estimate how wide a spread a clematis will have would just be another guess. As I have said previously, if you want your plant to get wider, try layering stems along the ground and you could potentially make any clematis as wide as you want. That way you don't have to worry about someone telling you that a certain clematis gets a certain width.

Miguel, layering is a great idea. Can I layer any of my type 3 varities? Is there a particular time of year that is bestto start this process?
