King James 1st is a traditional English mulberry, dating from the reign of James 1st in the 17th century. It is also widely known as Chelsea.
It remains the most popular of mulberries, and is notable for the flavour of the fruits. These are a black/red colour, and should ripen in the middle of the mulberry season - around the end of August in southern England.

King James 1st is self-fertile and does not need a pollination partner, although fruiting may be improved if there is a compatible tree of a different variety nearby.
Important: advice about pollination
Mulberry trees are self-fertile, easy to grow, and tend not to suffer from diseases. They are hardy trees and will grow in almost any situation, but you will get the best results if you can plant in a sunny open spot.
King James is fairly precocious by Mulberry standards, and you should start getting mulberries after about 4 years or so.
As with all mulberry trees, pruning is best avoided and is rarely necessary.
Keep the tree well-watered over spring and summer for the first 2-3 years after planting, and feed regularly until the tree has established.
