I tried Romanesco last year from seed and even though the plant grew to 4 ft high by 4 ft wide, it never grew a head!?? Tried again this year. Planted first week in May and it's now August and larger than 3'x3' with no sign of a head. Both plants in full sun in a raised bed in Zone 6a. Does anyone have an idea of what is wrong? Did I start it too late?
Is it too late for another try at a midsummer planting?
