Cyrtosperma Johnstonii is the plant that started my whole addiction to aroids. This plant produces long stems that look like reptile skin with pink brown and red streaks. The petioles also have small dark thorns that give this plant a prehistoric look. The leaves are arrowhead shaped 2 to 4 feet long dark green with pink to red veins. The flowers are held high on the petioles and are a black spath with a white spadix. Native to the Solomon Islands this rare and exotic plant grows in damp swamp like areas that stay very warm. So keep the plants in a warm greenhouse with regular watering or in tray with heated water. I have found in the past the plants can grow in cooler greenhouses if the water temps is warm. My plants grown in the greenhouse tend to stay around 3 to 5 feet tall if given the room and great conditions plants can grow 7 to 9 feet tall. One of the most impressive aroid plants I know of and a person favorite of mine.
