"Sandy - did you once mention growing 'Black Beauty' in a pot?"
Black Beauty zucchini? I don't think I've ever grown that variety, so I hope I didn't... LOL . But, along those lines, I have some planters that are similar in size to Earth Boxes that I might try growing zukes in this summer.
To my knowledge, zucchini are pretty much all bush-type plants. I'd actually like to grow some vining summer squash on my trellis, because it saves so much room in the garden... I have some seeds for "Trombocino" that I want to plant this year to see how they compare. (Not sure that's the correct spelling, but it's close)
