Roses are not considered to be shade-loving plants.

They require a minimum of four-to-six hours of direct sunlight daily in order to perform their best.

There are a few exceptions. For instance, the petals of some dark red roses tend to discolor (or burn) in hot sun and a bit of shade during the hottest part of the day is recommended to prevent this.

However, the General Rule of Thumb is: roses are not shade-lovers.

Roses are like English ladies- they love sun in the morning and shade in the afternoon. (This is an old proverb.)
