Privacy screen vines

(Question)

I am erecting a privacy screen in my rear yard. Hopefully, the vine, rose, or other plant will be dense thereby eliminating openings. Secondly, it would be great if there was a noticeable flowering component. Essentially, the privacy is only required for patio weather.

As the area is in the rear is north facing and in the rear yard, the hours of direct sun are limited to about 4 hours especially in the area about 3 feet above ground level.

Thank you for your question about growing a vine on a privacy screen in a north location.

There are many lovely flowering vines available for this purpose.  Unfortunately many require full sun.

Generally most clematis require full sun, but there are a few varieties which will bloom with only four hours of sun a day. ‘Nelly Moser’ is a clematis that is recognized as good for a northern wall; other possibilities are ‘Silver Moon’ and ‘Dawn.’

An  option that is more slowly to establish is Schizophragma hydrangeoides (Japanese hydrangea).  It is a woody plant that grows in zones 5-8.  It spreads about 6-9 feet.  In June to July it has is covered with beautiful white clusters of lace cap flowers which will also provide lovely interest in the evening light. In the fall the foliage turns yellow.  It grows best in part shade to full shade in rich, medium moisture and well drained soil.  Pruning should happen in late winter to early spring.

Additional options for your north privacy screen are Dutchman’s Pipe, Aristolochia macrophylla,  and Honeysuckle, Lonicera.  This web site provides excellent information about the Dutchman’s Pipe: http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=j410

Honeysuckle is a very popular and easy to grow vine.  Its yellow to bright red blossoms attract butterflies and hummingbirds and are extremely fragrant, a nice bonus for a patio area.  Give it moist, organically rich soil and it will take off. You will want to prune the honeysuckle in the fall or winter when the plant is dormant to control its spread.
