One of my favorite Amorphophallus species is maxwellii. It has a great look white to gray petioles with odd blotches and a size between 3 and 5 feet tall. Flowers are large black held high on a petiole. Plants are not often listed forsale. Plants offered are grown in 4 to 4 1/2 inch pots. Tubes should be around dime to quarter size.
