Assuming it is still there, I presume in your climate this thing just grows and grows quickly with no rest? If 2 feet tall now, it could be blooming size in a matter of a few months. If the plant looks quite healthy and has a lot of nice leaves, if no bugs or nasties, were I you, I would go for it.
IIRC you are just starting with Brugs with the seeds - right?
Look at pics here and elsewhere and you will know what a healthy Brug looks like.
If you have not found it yet, I find this site useful:
