The Rose painted calathea, with it's clump forming habit is a species that's more than happy growing and being displayed indoors showing off it's striking leaves and suits growers requiring an undemanding plant. They also make an attractive choice of plant displayed on balconies and patios when temperatures are warm enough.
How it looks: It's all about the foliage with this one. The green elliptic leaves display pinkish colored stripes from the midrib. The midrib is also pinkish in color, although this and the stripes will turn white when the plant matures. These leaves fold up slightly when night time arrives which gives a grower the additional feeling of the plant being alive. The leaves grow at the top of the stalks and reach up to 30 inches tall.
Flowering: Calathea roseopicta will bloom during the summer with small white and purple flowers which are non-showy, but still nice to see.
Displaying: Two important factors to consider when displaying this plant is not to seat it near cold drafts or in direct sunlight. Displaying within a shaded room where you can place the plant at a height level with a table will enable you to show off both sides of the leaves.
