Both are deciduous, so there will be light and water in spring. Even
bluebells don't do well under evergreens, even when there is plenty of
water.

Both had good leaf cover before the lily of the valley appeared, so I'm
not sure how valid the argument about light is. Water is likely to be
the key factor.
