Some noteworthy blue hostas:
Big Daddy, Love Pat, Blue Umbrella, Dorset Blue, Blue Ice, Blue Moon, Big Mama, Blue Mammoth and Blue Mouse Ears.
Plant a single specimen hosta like ‘Big Daddy’ in a shady corner and let its lush, mammoth foliage serve as a focal point. Or, go the miniature route and plant a bed of ‘Blue Mouse Ears.’
Fine Gardening Magazine says, “Petite, rubbery leaves in a soft shade of blue make the award-winning ‘Blue Mouse Ears’ easy to love. Low growing and perfectly symmetrical, this adorable hosta blooms profusely in midsummer, sending up stems that peak at just 1 foot tall.”
