Why do trees have blossom?

Fruiting trees rely on insects for pollination, so their flowers tend to be showy, colourful and sweet-smelling to signal that nectar is available. In contrast, wind-pollinated trees tend to have drooping or hanging clusters of flowers that are inconspicuous and green or brown in colour.

What is blossom?

Many trees flower in spring, but what makes it blossom?

Botanically speaking, blossom refers to the flowers of stone fruit trees in the family Rosaceae such as plums, cherries, apples and hawthorns. They usually flower abundantly over a relatively short period in spring and range in pastel colours from creamy whites to deeper pinks.

When to see blossom in the UK

Orchards, parks, gardens, woodlands and along streets and hedgerows are all good places to spot blossom.

Here at the Woodland Trust, we look after more than a thousand woods across the UK that are free for you to explore. Find a wood near you and enjoy a spring walk.

Flowering times

Climate change is causing UK plants to flower almost a month earlier on average, according to a study using our Nature's Calendar observations.

Is spring arriving earlier?

Although we love the arrival of spring, year-on-year early springs can have catastrophic consequences for wildlife. If flowers like blossom appear earlier, it leads to an ecological mismatch where hungry chicks hatch too late to feast on abundant insects that feed on the flowers.

The earlier that spring arrives, the harder it is for birds to adjust the timing of their breeding to match the peak in insects.

You can let is know what's happening to wildlife in your area. Anyone in the UK can submit a record to Nature’s Calendar and it helps scientists to understand how climate change is affecting ecosystems across the UK.
