Variety variation

I purchased some seeds in Amsterdam from a single variety. The 9 plants that germinated all look different. Is this possible? How come plants of the same variety all grow in different patterns?

The ‘variety’ that you are growing is not stabilized variety at all, which should be inbred along two or more liens for about six generations, but a hybrid made from other unstablized hybrids. The result is that the plants are extremely variable. Take clones of them all. After harvest, select the plants you like best and continue those lines, eliminating the others.
