Whitebeam
Sorbus aria · also: Common whitebeam
Whitebeam is a native tree of 8–15 m, recognisable by its oval, double-toothed leaves with a brilliant white, felted underside: when the wind blows through it, the whole tree looks silvery. In May it bears white flower heads for bees and hoverflies, and in autumn orange-red berries for thrushes and starlings. In the wild it is rare, on dry, chalky soils. It tolerates wind, chalk and drought and stays fairly compact: a tough street tree and an excellent tree for an ordinary garden.
Caution: Whitebeam can pass fireblight to apple, pear and quince: don’t plant it right next to fruit trees.

Identify
Whitebeam: how do you recognise it?
- Habit
- Tree of 8–15 m with an egg-shaped to rounded, fairly compact crown; often narrow and upright when young.
- Leaf
- Alternate, 6–12 cm, oval, irregularly double-toothed, with 10–14 pairs of parallel veins. Dark green above, white-felted below: in the wind the tree looks silvery.
- Bark
- Smooth and grey, later finely cracked.
- Flower
- White flower heads in May.
- Fruit
- Orange-red to scarlet berries (1–1.5 cm) with small pale speckles, in autumn.
- Difference from Swedish whitebeam
- Swedish whitebeam has leaves that are lobed towards the base and grey-felted, not brilliant white.
Flowering: May · Harvest and fruit: September–October · Pruning: July–August and December–February
Identify by feature: White or silver underside · White blossom · Orange berries
Looks like it, but isn’t
- Swedish whitebeam Sorbus intermedia: the leaves are lobed towards the base and grey-felted, not brilliant white. Difference from Swedish whitebeam
- Goat willow Salix caprea: wavy leaf margin, catkins in March and no berries. Difference from goat willow
In your garden
Why grow it?
- A native tree that fits an ordinary garden: 8–15 m tall and about 6 m across.
- Silvery foliage, white flowers in May and orange-red berries in autumn.
- Tolerates wind, chalk, drought and urban soil: also for an exposed or dry spot.
- Flowers for bees and hoverflies, berries for thrushes and starlings.
Whitebeam: where does it grow best?
- Full sun; in shade it flowers less and the crown stays thin.
- Dry to normal, well-drained soil. It loves chalk, but also grows on other soils, as long as they are not wet.
- Tolerates wind, even on the coast, and urban soil: a good street tree.
- Allow for a crown about 6 m across: it fits an average garden.

Goes well with
- Field maple: A native tree that, like whitebeam, tolerates chalk, drought and wind; together a sturdy woodland edge or hedgerow.
- Wayfaring-tree: A native shrub of dry, chalky soils, with white flower heads in May and berries that turn from red to black.
- Wild privet: A native, semi-evergreen shrub for chalky soil; flowers in June for butterflies and bees.
Good and bad companions
Goes well with
- Tolerate the shade under this tree: oregon grape, rhododendron, oleaster, japanese skimmia, garden privet, camellia, laurustinus, box-leaved honeysuckle
Best kept away from
- Fruit trees that can catch fireblight from this plant: apple, pear, nashi pear
Maintenance
Whitebeam: when and how to plant it?
- Plant from November to March, in frost-free weather, bare-root or root-balled.
- Dig a generous planting hole, loosen the bottom and set the tree at the same depth as before.
- Put in a stake on the windward side and tie the tree loosely.
- Don’t plant it right next to apple, pear or quince trees: they can pass fireblight to each other.
- Water during dry spells in the first year.
Care
- Watering
- During dry spells in the first year; after that it copes well with drought.
- Feeding
- Not needed; on poor soil, a little compost in spring.
- Water shoots
- Remove water shoots on the trunk as soon as you see them.
- Fireblight
- In summer, check for twigs that suddenly blacken and wilt, as if scorched. Cut them out generously and disinfect your secateurs.
Tip: Got a small garden? Choose the variety ‘Lutescens’: it stays more compact, and in spring its young leaves are covered in creamy-white down on both sides.
Whitebeam: when to prune it?
Pruning months: July–August and December–February.
When: Dead, diseased and broken branches can be removed at any time of year. Formative pruning in winter or after flowering.
How:
- Little needed: remove crossing branches and water shoots.
- Train a young tree with a single leader and a clear stem tall enough for the spot, e.g. 2 m above a path.
- Cut out branches with fireblight at least 30 cm below the visibly affected part, in dry weather.
Caution: Can carry fireblight.
Propagation
- Sowing
- In autumn, take the seeds from ripe berries and sow them straight away outdoors in a pot or seedbed. They need a winter’s cold and germinate in spring, sometimes only a year later.
- Grafting
- Varieties such as ‘Lutescens’ are grafted onto a rootstock; best left to a nursery.
Whitebeam: how does it get through the winter?
Hardy throughout Belgium: no protection needed.
- Fully hardy.
- The berries sometimes hang on into winter, until thrushes, fieldfares and starlings eat them.
- In the bare crown you can easily see which branches cross: a good time for formative pruning.
Diseases and pests
- Fireblight: Flowers, twigs and leaves suddenly wilt and turn brown to black, as if scorched; young shoot tips bend over like a shepherd’s crook. Cut out diseased branches generously in dry weather and disinfect your tools.
- Aphids: Curled leaves in spring, with sticky honeydew. Ladybirds and birds usually deal with them; don’t spray.
- Wet soil: On wet, poorly drained soil it declines and branches die back. Choose a dry to normal spot.
Through the year
- January: Formative pruning in frost-free weather; plant bare-root trees.
- February: Finish formative pruning; plant.
- May: Flowering: white flower heads for bees and hoverflies; the young leaves are silvery white.
- June: Check for aphids and fireblight.
- July: Summer pruning after flowering; cut out diseased twigs.
- August: Finish summer pruning.
- September: The berries turn orange-red: food for thrushes.
- October: Take the seeds from ripe berries and sow them outdoors.
- December: Formative pruning can start again; plant bare-root trees.
Use
What can you use it for?
- Garden and landscape
- Tough street and garden tree that copes well with wind, chalk and drought.
- For wildlife
- Flowers for bees and hoverflies; the berries for thrushes and starlings.
- Food and drink
- The berries are ripe and edible after frost, in jelly, but rather mealy.
Edible and useful
- Berries (September–October)
- The orange-red berries in September and October. They are only good after the first frost, or once they have become slightly overripe and soft (bletted); they then taste sweet and mealy. Use them cooked, for jelly or purée, preferably with apple.
- Storing
- The berries can be frozen on their clusters. Jelly keeps for a year in sterilised jars.
Caution: As with all rowans: do not eat them raw in large amounts, and sieve out the seeds. Do not confuse whitebeam with poisonous red berries such as those of yew, holly or honeysuckle; whitebeam is easy to recognise by its leaves with brilliant white, felty undersides. Whitebeam is often planted along busy roads: pick away from traffic instead, and never eat anything you have not identified with certainty.
Eating and using is at your own risk: see the terms of use.
Recipes
- Whitebeam and apple jelly (Jelly · ± 3 jars of 250 ml · 1 hr 30 + overnight dripping)
- Whitebeam and apple sauce (Compote · ± 3 jars of 250 ml · 45 min)
- Whitebeam and pear chutney (Other · ± 3 jars of 250 ml · 1½ hrs + 2 weeks maturing)
Good for wildlife
- Birds
- Berries, seeds or insects as food, or a place to nest.
- Bees
- Nectar and pollen for honeybees and wild bees.
- Hoverflies
- Open flowers for hoverflies; many of their larvae eat aphids.
You and this species
Did you know?
- Its Dutch name, meelbes (‘mealy berry’), refers to the mealy flesh of the fruit. Whitebeam tolerates wind, chalk and drought, which makes it a good street tree.
- In spring the buds open like little white candles: the young leaves are white-hairy on both sides and only turn green on top later on.
- The berries are ripe and edible after frost, in jelly, but rather mealy.
- Whitebeam hybridises with rowan and wild service tree. Such crosses gave rise to species like the Swedish whitebeam, which set seed without fertilisation and so became stable species.
- In Belgium, whitebeam grows wild mainly on limestone rocks and slopes in Wallonia, for example in the Meuse valley.
