This grower is sure of this plant identification.
I've grown two in a peat pot and found that if you did want to grow them on separately it's easy enough to split them by soaking the whole thing in water.
Cucumis sativus ‘Marketmore ridge cucumber’ (Cucumber). This variety produces fruits up to 8in. In length, with a good yield of short, attractive, dark green fruits. Grown in the open garden.
It may need staking. Harvesting may start in Late summer. Harvesting may end in Early autumn. Fairly difficult to grow.
