Deciduous trees come into their own as their leaves change colour. A favourite of mine is the Japanese maple, which breath-taking colour changes are a must have for any size garden. The leaves of flowering cherry trees change to gold and fiery red before they fall.
Amelanchier lamarckii (snowy mespilus) provides on all fronts with green foliage in summer that turns orange and red in autumn. White flowers bloom in spring, followed by purple-black berries. Their autumn colour has a touch of Halloween spookiness about it.
For some real spectacular Halloween interest, Physalis alkekengi (Chinese lantern) have papery-textured red fruit covers. These are inflated and lantern-like because they shield the red berries.
