Utrecht outing 'St. John's'

For centuries, a specialty of (East) Utrecht growers. In early summer (June 24th, St. John's Day), the young onions are harvested. Leave some plants in place or replant them in the autumn. Both the hollow stems and the onions have a typical, pungent, garlic-like taste. Delicious raw in salads. We supply the bulbs in summer and autumn. Outside the 'dry' season, we sometimes supply them in pots, which can be planted all year round. Give them plenty of organic fertilizer in winter, preferably on a raised plant bed.
Prince Bernhard loved these onions! Perhaps because they have also been known among growers and hobbyists in Germany for centuries... Such an onion was brought to the US by Jesuits in the 17th century and embraced there by the O'odham Native People. I found them online under the names “Tohono O’Odham Onion” or “l’Itoi Sivol Onion”
