Unique blue Hosta.
Hosta 'Delirium' is the all-blue sport of the brilliant Hosta 'Superfecta'. Rob Mortko tried to produce 'Superfecta' in his tissue culture lab in Kansas USA but found out that it was a difficult one to multiply without losing its variegation, this did drive Rob crazy and therefore the name 'Delirium'.
