Calypso Cucumber (F1 Hybrid, 50 Days)

Calypso was developed by the University of North Carolina Agricultural Experiment Station as a very high yielding pickling cucumber for commercial growers. However, it is a fine choice for home gardeners as well. The blocky (1” x 3”) cukes are a very dark green with a minimal white spine. It is a gynoecious variety with a small percentage of a male pollinator added. Resistant to powdery mildew, cucumber mosaic virus and anthracnose. 

 25 seeds


Cucumis sativus

Germination: 4-10 days

Germination Temperature: Optimum soil temperatures 70-85ºF

Seed Sowing Depth: 1/2-1" deep

Sowing Indoors: 3-4 weeks before last frost. Provide 70-85ºF soil temperature. Sow 2-3 seeds per cell/pot. Sowing into individual biodegradable peat/cow pots reduces root damage when transplanting. Transplant 36-48" apart after last frost. 

Sowing Outdoors: Sow after last frost when soil temperature is over 70ºF. Sow a few seeds every 36-48". 

Harvest: Check and pick every day to keep the harvest flowing.

Tips: Plant in fertile soil, amended with compost or well rotted manure and keep well watered. Trellising the vines allows for good air circulation, takes up less space and provides shade for heat sensitive crops like lettuce. They benefit from growing on black plastic and by using row covers for weed, insect control, and more rapid growth.

Too few seeds

I growcukes for pickles. Packing only 25 seeds per pack seems a waste. I bought 3 packs this year and still ended up needing more. (Germination rate approx 65 to 70 %). I wish you would increase to number of seeds to what most of your competitors do. I like your company and wish you success.

99+ lbs of cukes in one month, 15 ft row.

My Calypso cukes only bore for one month before they succumbed to powdery mildew. But I don't fault the plants. Every cucumber I've ever grown has gotten diseased. But these pumped out 99.12 pounds of fruit before they bit the dust. That was from 12 plants in about 15 feet of row. Next time I would plant them farther apart, both for better air circulation and to make it easier to find all the fruits. Pick these every day and you will have more crunchy pickles than you know what to do with.

One Season, Three Crops

We have grown Calypso cucumber several years. Here on the coast of NC we start our first crop in late March for May harvest. A second crop started in June takes us through late summer. In mid-August we start our third crop for fall harvest. We have found this cucumber to be disease resistant in the hot and humid climate.
