Just ordered ours and, as usual, have gone for 1kg bags of several varieties. This year Pentland Dell, Maxine and Manitou all did brilliantly so 2kg seed of each; others ok. moderately bad late blight year overall but scab less than usual. Harmony produced a few good sized ones and, literally, hundreds of marble-sized ones - see photos. They were also very high in the ground and we didn't ridge them enough (fractured shoulder scuppered me this year and OH can't do everything). We don't go for the black-dark blue varieties as we can never see them when digging - peaty soils. Overall yield about 80kg so enough for us and family for the year all being well. One of those for this year is Setanta.
