6 inches. Isn't this a beauty! A complete favorite around here, the Calathea Warscewiczii loves to show off its dark green leaves with fancy fishtail pattern. It can grow up to 20-40 inches high and wide, so let it live indoors as a table plant or short bush.
Calathea like bright, indirect light but are very sensitive to water. We recommend watering with distilled water, making the soil moist but never soggy. It's a little more fussy than some of the rest in it's class, but well worth the effort.
