My sanguinea (deceased) pitchers max out at about 2 inches, leaf span 3 inches. Managed to survive for four years before giving out (leaves and pitchers becoming smaller, gradual cease in growth.
The last time I measured the pitchers the size was like less than 1 inch, you could mistake it for gracilima. Previous 3 pots of green and orange varieties bought from cameron highlands also perish within a year. Guess other growers have better luck due to environment differences.
