Native to rainforests, Syngonium Pixie will grow happily without extra warmth and humidity, but give them both and they'll thrive for you.Evenly moist is the happy place for a Syngonium Pixie. They're more forgiving than many if you're an over- or under-waterer though. The Pixie stays more compact than most. A mix of about 3/4 potting soil and 1/4 perlite or similar will do the job nicely when potted.
