Description
The Blue Jarrahdale Pumpkin is an heirloom variety of ornamental pumpkin that is as beautiful as it is delicious. Its deeply ribbed blue-grey skin protects its tasty, orange flesh that has a mild, pleasantly sweet flavour. Use them to make gratins, soufflés, pies, or eat them sautéd or fried. They can also be used to make fruit pastes or tasty, uncommon jams. The fruits of this pumpkin can be kept for 4 to 9 months. Sow in spring and harvest from July to October. Easy to grow in warm conditions, in very rich, well-watered soil.
The pumpkin, in Latin Cucurbita maxima, belongs to the family Cucurbitaceae. It is a plant native to the tropical regions of South America. 'Jarrahdale' is an Australian variety that looks a bit like 'Hungarian Blue'. It is an annual plant that develops long, very vigorous, trailing or climbing vines, which cling onto any support by the means of tendrils. The leaves are large, simple, heart-shaped with 5 rounded lobes and are marked by palmate veins. They flower from spring to summer, depending on the date of sowing. There are two types of flowers in pumpkins and squashes: female and male flowers. They are made up of large, limp, yellow-orange petals. About 6 months after sowing, the female flowers produce large, slightly flattened, round fruits with very pronounced ribs that weigh 3 to 10 kg. Their colour is grey tinged with slate. They are borne by a thick spongy stalk with a rounded section. The flesh is dense, dry, fibrous and of good eating quality. The large white seeds are 2 to 3 cm long, oval, flattened in shape and are sometimes eaten roasted. They retain their germinating power for 4 to 5 years and emerge after a minimum of 9 days.
Sow this pumpkin in the spring, under a heated cover, in little pots, or directly in the open ground, once all risk of frost has passed. Much appreciated in culinary dishes, pumpkins can also be used to create all sorts of original decorations in the home. They bring a touch of exoticism and whimsy to a fruit bowl, mixed with bunches of grapes, apples, pears, Virginia creeper leaves, mini pumpkins and many other things. Use its flesh to make soups, purées, gratins, soufflés and sweet or salty pies. You can also make jam with it.

Planting and care
Sow squash and pumpkins from March to May in 7 cm pots, or directly in the open ground when frost is no longer a concern. Use good quality soil enriched with garden compost. Sow 2 or 3 seeds together (in the same hole), at a depth of 1 cm. Cover the seeds, tamp down lightly and water generously with a fine spray. Place your pots in a bright place without direct sunlight, at a temperature of 20 °C.
Seed emergence will take 7 to 10 days. As soon as the seedlings have reached a height of 20 cm start to acclimatize them gradually to a temperature of 15 °C.
At the end of May, beginning of June, the temperature in the garden will be warm enough to plant out your young plants. Choose a place with plenty of sunshine that is sheltered from the wind. Add a good shovelful of garden compost to each planting hole.
Throughout their growth make sure that they do not run out of water. Pumpkins require consistently moist soil.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
