Large, slightly flattened onion, very pungent, keeps well
Long-day type—The name translates as North Holland Blood Red, and these beauties are indeed a lovely, shiny ox-blood red. Large, slightly flattened onions are very pungent, which makes them good keepers in spite of their rather thick neck. They can also be grown for scallions, as they often are in Holland. A good variety for Northern gardeners.Amaryllidaceae Allium cepa

Correct timing is important with bulb onions, if you don't plant them at the right time they won't do very well. The best onions are grown from transplants set out in October or November and wintered over to mature in June and July. Plant transplants right away, if possible. Transplants are happy if you apply a light mulch to help conserve moisture for uniform growth.
