Spring flowers in the ash's forgiving shade

Sandy, Bedfordshire Ash dieback threatens a tree that is unwittingly generous at both ends of the season

A line of trees on the green, their fresh bright leaves glazed with sunlight, take from the east and give nothing to the west. Oaks, sycamores and chestnuts bathe their crowns in the mid-morning rays and cast dark shadows on the ground, as wide as the trees are broad, as long as they are tall, with dappled haloes all around. The beeches are worst of all, offering the land beneath no chink in their green armour. No wonder so little grows under the canopy of a beech wood, a crowd of overlapping umbrellas giving shelter, blotting out the light.
