Sets of heritage cucurbits, from gherkin to potimarron, sown from April to May

The organic cucumber, courgette and squash seed set, one variety per packet, brings together 6 or 12 heirloom varieties of the same vegetable, from the Blanc de Paris gherkin to the Hokkaido red kuri squash. Sow from April to May, in pots or in place, at a depth of 2 to 3 cm; seedlings emerge in 4 to 6 days at 20 to 25 °C.

Cucumbers, squash and courgettes share the same family and the same sowing method, but their harvests differ considerably. The kits bring together heritage varieties such as Blanc de Paris gherkin, Lungo Verde degli Ortolani long cucumber and Gele Tros yellow cucumber, and on the squash side Marina di Chioggia, butternut and Hokkaido potimarron.

🥒 Three species, three growing schedules

Your cucumber is eaten immature and picked every 2 days for 2 months, which makes it the most demanding of the three when it comes to regular attention. The courgette is also harvested young, at around 20 cm, and a single plant is quite enough for a family since it produces without a break from July until the first cold weather. The squash follows the opposite logic: it stays in the field until fully ripe, is cut in October with a piece of stalk attached, then keeps for several months in a cool room. You therefore do not manage these three species at the same pace, even if they are sown in the same week.

🍈 The kiwano and the cucamelon

The box of 12 cucumbers contains two fruits related to the cucumber, but of a different species. The kiwano, or African horned cucumber, has an orange skin bristling with spikes and a green, jelly-like flesh with a tart melon flavour; it grows like a climbing cucumber and is harvested when the skin turns yellow. The cucamelon, a tiny striped fruit the size of a grape, is eaten whole with a hint of lemon in the aftertaste. Both fruits need the same care as their relatives, namely trellising and soil that never dries out completely.

Cornichon Blanc de Paris

Heritage variety with pale skin, harvested very young for pickling in vinegar.

Lungo Verde degli Ortolani

Italian long cucumber, low bitterness, good in salads and easy to train up string.

Marina di Chioggia

Bumpy blue-green squash with dense, sweet flesh, which keeps until spring.

Doubeurre

The classic butternut squash, with orange flesh and a solid neck, the easiest to cook.

Below 15 °C, the seed rots before it germinates

These large seeds above all dislike cold soil. At 15 °C, a cucumber seed takes nearly 2 weeks to come up, whereas it emerges in 4 days in soil at 25 °C; any cooler and it soaks up water, sits dormant and eventually rots. So wait until late April or early May, depending on your region, before sowing in place, or start them under cover in pots. Then sow the seeds 2 cm deep and water just once, generously, rather than soaking the planting hole every day.

Peat pots planted out with their root ball

Cucurbits do not respond well to having their roots disturbed at transplanting, and a stressed plant takes time to recover. Biodegradable pots are planted whole, rootball and all, without any contact with the roots. This lets you get started 3 weeks before the direct-sowing date, giving you an equally earlier harvest.

📏 Floor space first

A trailing squash covers several square metres in a summer and clings to everything it meets, including neighbouring rows. A non-trailing courgette fits in one square metre, provided you leave air around the crown. The cucumber, for its part, is trained vertically on a string or a net and then takes up only 30 cm of row, which makes it the only one of the three that really suits a small garden or a soilless growing system.

⛏️ Station seedling sowing

The traditional method remains the most reliable. Place 3 seeds in the same spot, under 2 cm of soil, then thin out the two weakest plants once the first true leaves have appeared. This makes up for the uneven germination rate of these large seeds without multiplying the rows. Allow about 6 days for germination in soil at 20 °C. Space the planting stations one metre apart for courgettes and two metres apart for trailing squashes.

🐝 Seeds that keep for a long time

These species are among the most stable in the vegetable garden when it comes to storage: kept dry, cool and away from light, cucumber and squash seeds stay viable for at least 6 years, often longer for squashes, so a box of 12 varieties covers several seasons. If you want to save your own seed, bear in mind that varieties of the same species cross with one another via bees: a courgette and a patty pan, both Cucurbita pepo, give hybrid seeds if they flower side by side, whereas a butternut does not cross with a red kuri. The Cucumber Long Chinese and Courgette Black Green pages present two varieties sold on their own.

Frequently asked questions

8 questions

6 key questions, 8 in the detailed view

Which varieties are found in the cucumber and courgette sets?

Box	Example varieties
Cucumber 6	Cornichon Blanc de Paris, Lungo Verde degli Ortolani, Gele Tros
Cucumber 12	The same types, plus kiwano, cucamelon and a Russian cucumber
Squash 6	Doubeurre, Marina di Chioggia, Uchiki Kuri red kuri squash, Halloween pumpkin, giant pumpkin, Neapolitan squash
Squash 12	The same, plus white patty pan, Rouge vif d'Étampes, Bleu de Hongrie, Provence butternut squash, Sweet Dumpling and mini pumpkin

Each packet carries the name of its variety. Kiwano and cucamelon, which are related to the cucumber, are grown like it, trained up supports.

Can seeds be sown directly in open ground?

Why do the first flowers drop without setting fruit?

Why are my cucumbers bitter?

Do the squashes in the set cross-pollinate with one another?

Only within a single species. The squash box brings together three:

Cucurbita pepo: patty pan and Halloween pumpkin, like the courgette.
Cucurbita maxima: Hokkaido red kuri squash, Marina di Chioggia, Rouge vif d'Étampes, giant pumpkin.
Cucurbita moschata: butternut, musquée squash, Neapolitan squash.

Cross-pollination does not change this year's fruit; it only affects the seeds you would save.
