There are many gorgeous varities of calathea, each with unique painterly leaf patterns. Calethea Freddie has elongated, light green leaves with dark green "chevrons." These lovelies are native to Brazil and Central America. They prefer medium to bright indirect light, but too much sun with fade their colors.
Water them weekly: calathea prefer consistently moist (but not soggy) soil and higher humidity. They would be happy to be occasionally sprayed with a showerhead or sink sprayer.
Calathea are non-toxic to pets!
