It's not really a tower, just vines climbing up some strong twine to the top of a trellis that goes over the center path of the veg garden.
It's happy and covered in bloom. In the mornings, this thing is full of bees and really noisy.
This particular variety is De Bourbonne, which are bred to stay small. Assuming that you go out every day to measure and pick them. And assuming they don't get lost in all the leaves. It's easy to miss them and it only takes a day for them to get not small.
Not small as in big. Really big.
Bottom line: I like this variety a lot and will be doing them again.
