The tallest ones in my garden are
Banana Smoothie (Registered at 64", but more normally in the 50's for me)
Mascara Snake (Registered at 57", and I think I've had some that tall. I know it gets pointed out that this plant's scapes can lay down if they get too tall and have too many blooms, so I tend to stake the taller scapes just in case they start getting any ideas.)
