Beat the scourge of the allotment! A superb early maincrop onion with good Downy Mildew & bolting resistance. The full-flavoured, copper-brown skinned, round-oval bulbs store well too.TOBY'S TIP: The introduction of onion Santero is a real plus. On our trials, we have had real problems with downy mildew, but Santero has grown through the fungal attack.
