A deciduous tree growing to 30 m (98ft) by 15 m (49ft) at a medium rate. It is hardy to zone 5 and is not frost tender. It is in flower in July, and the seeds ripen in October. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by Bees. It is noted for attracting wildlife. Plants are fairly self-sterile.
The seed is best eaten roasted, as the sweetness comes out in the flavour.
Prefers a good well-drained slightly acid loam in a sunny position but it also succeeds in dry soils. Once established, it is very drought tolerant. Plants are very tolerant of highly acid, infertile dry sands. The dormant plant is very cold-hardy in Britain, though the young growth in spring, even on mature plants, is frost-tender. The sweet chestnut is often cultivated for its edible seed in warm temperate zones, there are several named varieties. Sweet chestnuts require a warm dry summer in order to ripen their fruit properly in Britain and even then these seeds are generally inferior in size and quality to seeds grown in continental climates. Flowers are produced on wood of the current year's growth and they are very attractive to bees. Plants are fairly self-sterile.
Due to the threat of Sweet Chestnut blight within the UK and for the 2014/15 season, we will not offering for sale any bare rooted trees. There is an ongoing inspection by FERA plant health inspectors. Who are creating a location map of all UK trees, as well as an inspection for the blight. When have been given the all clear we will offering scions from our own mother plants.
