The 'Ulysse' potato is a new and original French selection, derived from two proven varieties: Ditta and Bleue d'artois. It produces oval and regular tubers with a beautiful slate blue-violet skin and flesh. In the garden, it is an easy-to-grow mid-late variety that offers a good yield of medium-sized potatoes and is resistant to mildew. It can be stored for a long time in cool, dark conditions. In terms of cooking, it is versatile, and its firm flesh marbled with white has a surprising flavor. Try slicing it thinly into chips, preparing it as mashed potatoes, or steaming it. It can be planted from March to May for a harvest approximately 120 days later, from June to August.
These plants are from organic farming and carry the AB certification.
The potato is a root vegetable that has become essential in the vegetable garden and on the plate. It is a perennial plant cultivated as an annual, developing tubers as storage organs on its rootstocks. Apart from a few varieties like Belle de Fontenay, the plants produce small flowers in summer. Each plant will produce several potatoes, which can be stored for several months and cooked in multiple ways. The potato belongs to the Solanaceae family, like eggplants and tomatoes. Originally cultivated in the Andes, it was brought to Europe in the 16th century. It was only around 1750 that it became widely developed in France, thanks to Parmentier.
There are many varieties available. The tubers, which vary in shape, generally have yellow flesh, but can also be red, pink, or violet. Low in calories, potatoes are rich in carbohydrates, iron, and potassium.
There are 3 categories of potatoes, based on the flesh content:
- Firm-fleshed varieties have good cooking properties. These rather elongated potatoes have a fine and flavorful flesh. They are ideal for boiling or steaming and can also be stewed or pan-fried.
- Floury varieties are rich in starch and easily break apart. Fairly large, these potatoes are perfect for mashed potatoes or soups. They also make very crispy fries as they tend to absorb less oil during cooking.
- Waxy varieties have a melting flesh while still maintaining good cooking properties. They can be used in various ways: pan-fried, stewed, or baked.
Harvesting: depending on the varieties and their earliness, potatoes can be harvested from May to October. Gently dig up the plants with a fork to avoid damaging the tubers. Let the potatoes dry in the sun for a day.
Storage potatoes should be harvested when the foliage turns yellow and withers. Early varieties are harvested 80 to 90 days after planting, semi-early varieties around 110 days, semi-late varieties around 120 days, and late varieties from 120 to over 150 days.
As for new potatoes, with their very thin skin and delicious flesh, they are harvested before maturity, 70 days after planting. Harvest them just after flowering, around May-June.
Storage: after removing any damaged tubers, store the potatoes in a cool, dry, and dark place. In the presence of light, the tubers turn green and produce a toxic compound called solanine. Early harvested varieties should be consumed quickly. Storage potatoes can be stored for several months. The storage duration varies depending on their earliness: late varieties can be stored the longest.
Gardener's tip: Grow potatoes as part of crop rotation, as they are often considered a cleansing crop. The hilling and root development leave the soil clean and loose after harvest. They also appreciate the company of legumes (beans, broad beans, peas).

Foliage
Planting: Potatoes need a light, deep, and rich soil. Choose a sunny location. Add well-rotted compost in the previous autumn, by scratching it into the soil to a depth of 5 cm (2in), after loosening the soil. Planting takes place under cover in February-March for early varieties. For other varieties, plant them from mid-March to May depending on the climate. Wait until the soil temperature is at least 10°C (50°F). The flowering of the lilac is often a landmark for starting the planting. Install several varieties in your vegetable garden to vary the pleasures!
Loosen the soil deeply and form rows 10 cm (4in) deep, spaced 70 cm (28in) apart. Place the tubers, sprout side up, every 40 cm (16in) (or 30 cm (12in) for early varieties). Cover with fine soil. When the plants reach 15 cm (6in), hill up by bringing fine soil to the base of the stems, to a height of 20 cm (8in). Hilling up will promote tuber formation and water drainage. You can hill them up again a month later. Mulch at the base of the plants, with thin successive layers of clippings mixed if possible with dead leaves. This protection, which allows the soil to stay moist, also limits weed growth.
Potato cultivation does not require watering, except in case of high heat. In this case, water the base without wetting the foliage to prevent the onset of fungal diseases.
Diseases and pests: Potatoes are susceptible, like tomatoes, to late blight. This is a fungal disease caused by the Phytophthora infestans fungus. Late blight develops in hot and humid weather. Small spots appear, white on the underside of the leaves and brown on the upper side. As a preventive measure, here are some tips to reduce the risk of late blight:
do not grow several plants from the Solanaceae family in neighboring rows: potatoes, tomatoes, eggplants, peppers, chili peppers, as they are susceptible to the same diseases
in terms of rotation, wait 4 years before growing a plant from the Solanaceae family in the same location
space the plants, both within and between rows, to promote air circulation and prevent rapid disease spread
if you need to water, do not wet the foliage
spray Bordeaux mixture or preparations such as horsetail decoction or garlic infusion
The harvest can also be affected by the Colorado potato beetle, an insect of the order Coleoptera. You will recognize it by its yellow head and its yellow and black striped body. The best solution, although a bit time-consuming, is to remove them as they appear. As a preventive measure, sow blue flax seeds between your rows of potatoes. Sow from April to June in shallow furrows. In addition to its repellent effect against Colorado potato beetles, flax will brighten up your vegetable garden with its pretty little blue flowers. You can also interplant peas between your rows of potatoes.
Other planting methods: The detailed planting method above is the most common. Other methods exist, such as mulch planting and tower planting.
Mulch planting involves placing the tubers on the ground and covering them with a layer of mulch. This protection will be added as the plant grows, with the tubers always being kept away from light.
Tower planting or container planting is practical for small spaces but requires regular watering. The tower can be constructed from various materials (wood, wire mesh, bag, tires). The tubers are placed on a bed of potting soil or compost. As the plant grows, it is covered with more potting soil, leaving only the topmost leaves exposed, and so on until the top of the tower, allowing the tubers to form at various heights within the container. Harvest when the foliage has withered.

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).
