1. Mostly PSB? Only because folk haven't appreciated the delight of WSB!!
2. P/WSB takes up too much space? But it crops for 3 months - as opposed to most other varieties, which may be in one tidy row, caterpillars willing, but which all come in at the same time & you spend hours trying to pass them on to your friends?
3. Do agree that Romanesco is about the only one that freezes acceptably.
