These are by far my favorite. I noticed a quote in another seed catalog, where a gardener described Costata Romanesca zucchini as something like "The only zucchini worth growing unless you are just thirsty." That was a very evocative statement! These zucchini not only are the butteriest, creamiest, densest zuke I've tried (and I LOVE zucchini), but they are also incredibly easy to grow. This seed came up for me with such vigor, and faster than other squashes I've grown. They shot out of the ground even when I planted them rather early in the season. I used raised beds, well-prepared. This type doesn't get funny when it gets big, so you can eat the lunkers. But they get HUGE. I found they make great dog food, too. I've noticed that this variety is not listed as being extremely productive, but I'm a zucchini lover who also feeds them to two large dogs, and I couldn't keep up with 5 plants. Two would likely be more than enough. They were big bush-types.
