Answer: There are a few ornamental (non-fruit bearing) trees you might consider. First, Snow Fountains Weeping Cherry (Prunus avium 'Snow Fountain'). This slow-growing dwarf cherry has graceful branches that droop to the ground. Each spring it dons a floral cloak of pure white flowers to rival the elegance of any ornamental. Reaches a height of 12-15?, spreads 6-8?. Hardy, disease and insect resistant.
Dwarf Flowering Almond (Prunus glandulosa): The dwarf flowering almond is a spreading, multi-stemmed shrub that grows 4 to 5 feet tall and 3 to 4 feet wide. Its chief value is in the showy flower, which is either white or pink, single or double, and appears in midspring.
You might also consider a dwarf weeping pussy willow. It doesn't flower but gets interesting catkins in late winter/early spring and the size is narrow enough to fit in the tightest spots.
Hope one of these suggestions appeals to you.
