Prunus padus Watereri tree is an ornamental variety of the native Bird Cherry tree. It only really differs from the wild Bird Cherry in its size and the length of the flower cones. It is a little less bushy than its parent and although it can be taller, it has an upright habit overall and its slender branches droop under their own weight at the tips, so it doesn't take up much space. The white flowers smell of almonds and have yellow centres; a beautiful sight in spring, when the tree is bursting with flower cones (called racemes) up to 20cms in length, and buzzing with bees and butterflies. In autumn the flowers are followed by a large number of small, (safe but inedible) black fruit that contrast well with the bold autumnal colours of the foliage. It isn't a spreading tree, so it's suitable for most gardens. Prunus padus Watereri trees can reach a height of about 15 metres.
This tree was bred in 1914 and was called Prunus padus Grandiflora at first. It has won both the RHS Award of Garden Merit for being both simple to look after and beautiful, as well as the Award of Merit for its cut flowers.
How Standard Trees are Measured:
All our standards are graded by their girth in centimetres - taken 1 metre above ground level. So, a 6/8 standard has a trunk with a circumference of 6-8 centimetres and an 8/10 standard has a trunk 8-10 centimetres. In any variety an 8/10 is taller than a 6/8 but the heights between different varieties can vary hugely. So standard trees are roughly 2.5 - 4.5 metres tall.
