Another cool, rare Philodendron variety that is slow growing, easy to care for and thrives even if you forget to water for a few weeks. As it ages, Ring of Fire shows off an array of colorful variegated leaves in shades of green, orange, red, yellow, pink and white! Best if grown on moss poles or trellis to support leaves that can grow up to 2' in length for a total plant height of 8' and 6' wide - remember this guy is very. slow. growing:). Be careful with Philodendrons as they are poisonous when ingested by pets and people.
