Description

Bunching Onion ‘Red Stemmed Welsh’ is a perennial heirloom variety. It has green stems with red bases up to 45cm long, which grow in clusters or ‘branches’. The red is more intense in colder climates. The taste is mild. This variety is easy to grow; it is suited to warmer areas though with less red developing. The young green tops can also be eaten. This variety forms clumps which can be divided.
Bunching onions, also called ‘salad onions’, ‘Welsh’ onions (although they are originally from Asia), Japanese Leeks or, mistakenly, “shallots”, are perennial plants that do not form bulbs.
Bunching onions are the same plant sold in shops as “spring onions” (or “green onions”).
For “spring onions”, sow multiple seeds (4–8) into the same hole and don’t thin them (that is, don’t remove any seedlings from each clump). Harvest of “spring onions” begins at about 70 days (10 weeks) from transplanting. Sow further seeds every two–three weeks to extend harvest. This is called “succession sowing”.
