Heavenly Bamboo (Nandina domestica Blush Pink™)

Any one else grow this? I bought 2 at Lowes yesterday and this website says they get 2 ft tall
https://southernlivingplants.c...

but the database says 6-8 ft

I looked at many sites online and have seen them at work and can not find anything listing them at over 3ft most at 2ft.

well I have the firepower one and it has not gotten past 2 ft in 6 years. I don't want these if they get 5 ft tall, but I am inclined to think the database is wrong, so I'm just going to ignore that part
