Will lilacs grow in the shade?

From what I've observed, pussy willows are a more or less sun-loving plant. They can grow and even produce some blossoms, in tight competition in the wild, such as in stands of brush or saplings--which is somewhat "shade" since it shades the plants heavily on the sides. Progressing to a real "woods" situation, other trees more vigorous than them may tend to overtop them, and the shade then begins to get so heavy that the pussy willows probably begin to do poorly and decline, and die prematurely I imagine.

But really overall, they are mostly a plant for either sun or light or partial or part-day shade.
