Most
clematis require at least a 1/2 day of sun or strong filtered light
to bloom well. Gardeners living in warm weather states such as California
that have very long growing seasons and very hot temperatures can
plant most clematis in a partial shade aspect. However, those living
in colder climates with a shorter growing season need to adhere
more closely to the following recommendations. The varieties below
are only some suggestions and by no means represents all the varieties
that can be grown in partial shade.
