OK, it looks like 3 parts ..........
At least in my garden, I have never had an issue with them 'failing' me.... Last yr was an AWFUL garden yr (and I had surgery at the start of gardening season) It was still the best in my garden, I looked for pictures but think I have them on a different hard drive..... The plants are very 'sturdy' and in a good yr have topped 7' . Which means I have to break out my ladder to get to the top

..( I 'tend to' my polants, but don't 'work' at having 'monsters', I can only work up just so many, lol).... The one thing I did learn about the goliath, it seems more than others.........When I think it's 'ripe', I need to 'leave it' a couple more days, they are much better if I have patience ..............
