As a seasoned gardener in Staffordshire with over 15 years of experience, I've grown my fair share of vegetables. One of the more underrated gems is the Jerusalem artichoke. Known for their nutty flavour and robust growth, they are a great addition to any UK garden. In this article, I'll guide you through the best varieties suited for our British climate and offer practical tips to ensure a bountiful harvest.
Quick Answer
The best Jerusalem artichoke varieties for UK gardens are 'Fuseau', 'Dwarf Sunray', and 'Red Fuseau'. These thrive in British conditions, offering excellent yields and resilience.
Understanding Jerusalem Artichokes
Jerusalem artichokes, also known as sunchokes, are native to North America but have found a happy home in the UK. They are not actually artichokes, nor do they have any relation to Jerusalem. Instead, they are a type of sunflower with edible tubers, prized for their versatility in the kitchen.
Top Varieties for UK Gardens
Fuseau
'Fuseau' is a favourite among British growers. Its smooth, pale skin makes it easy to clean, and it has a slightly elongated shape. Perfect for our temperate climate, it grows well even in the Midlands' slightly heavier soils.
Dwarf Sunray
If you're short on space, 'Dwarf Sunray' is an excellent choice. It doesn't grow as tall as other varieties, making it ideal for smaller gardens. Despite its size, it produces an impressive yield of nutty, tasty tubers.
Red Fuseau
For a splash of colour, 'Red Fuseau' offers a reddish-brown skin that stands out. It is just as hardy as 'Fuseau' but brings a unique visual appeal to your garden. The flavour is similar, with a delightful earthiness.
Growing Conditions
Jerusalem artichokes are not overly fussy but do best in well-drained soil with plenty of organic matter. Plant the tubers in early spring, around March, spacing them 30 cm apart and 10 cm deep. They prefer a sunny spot but can tolerate partial shade, which is handy given our unpredictable British weather.
Care and Maintenance
- Water regularly, especially during dry spells, to encourage tuber growth.
- Mulch around the plants to retain moisture and suppress weeds.
- Stake taller varieties to prevent them from toppling in strong winds.
Harvesting and Storage
Jerusalem artichokes are ready for harvest in late autumn, typically from October onwards. Wait for the foliage to die back before digging up the tubers. They store well in a cool, dark place, such as a root cellar, for several months.
| Variety | Height | Harvest Time |
|---|---|---|
| Fuseau | 1.5 - 2 metres | October - November |
| Dwarf Sunray | 1 - 1.5 metres | October - November |
| Red Fuseau | 1.5 - 2 metres | October - November |
