Philodendron martianum Flask Philodendron

Edward F. Gilman, Ryan W. Klein, and Gail Hansen


This dark green philodendron has 6 to 8 inch wide leaves which are 18 inches long. Flask philodendron is well suited to use as an accent or specimen planting or in mass as a ground cover or low shrub. It would be hard to find a small plant with a coarser texture. Plant on 3 to 4 foot centers in a mass planting to create a solid, dark green, two-foot-tall ground cover, or as a single specimen in a small-scale garden.
