I've started 4 varieties of cauliflower, 4 plants of each. They are fussy as Charlotte said, so the heads I get are usually pretty small. Occasionally I'll get one comparable to the smaller ones I'd buy at the farmer's market.
Charlotte, that garden of yours looks phenomenal.
Kellie, artichokes do really well for me here, but they take up a ton of space for so little yield. They're basically giant thistles. And they rarely survive the winter. So I've stopped growing them. Nevermind the work in eating one!
Chrissy, peppers aren't easy for me where I live. When I lived in the Midwest US, they were super-easy - plenty of sun and summer rains. In Western Washington, the season is short, the sun is lower in the sky, and it never rains in the summer. By September, I'm out there begging the peppers (and eggplants) to ripen. Some do, but some start rotting on the plant in the cold nights. Every year is a gamble.
I keep growing almost everything, because: A) I'm a plant addict, B) I keep shifting methods and varieties hoping I'll find the magic combination, and C) I'm a plant addict.
