A tree canopy in full leaf takes all the light away form the Forrest floor where the bluebells grow and as all plants need light to grow the bluebells must therefore grow and flower before this happens.
One could say why don't they leave it until after the leaves have come off the trees in autumn? If they did this then they would be starting to grow and flower in winter when the temperatures and weather are inclement and the amount of sunlight is falling to its minimum as the sun moves south.
Blue bells are deciduous plants and they lose their leaves because they only need them to produce food, but during winters, their is lesser sunlight and so they do not need leaves in that season.

Yes, elm trees do produce flowers, but they are often inconspicuous. The flowers are typically small and can be either perfect (having both male and female reproductive parts) or unisexual. They usually bloom in early spring before the leaves fully emerge, and the flowers are often wind-pollinated. While not showy, they play a role in the tree's reproduction.
Elm trees typically bloom in early spring, usually between March and April, depending on the species and climate. They produce small, inconspicuous flowers that can be yellow, green, or reddish in color. The flowers appear before the leaves emerge, allowing for effective pollination by wind or insects. After blooming, the tree quickly develops its foliage, which is characterized by the distinctive serrated leaves of the elm.
Dogwoods typically bloom around April 15th.
