Calathea burle-marxii (Ice Blue Calathea) is an attractive small shrub, native to Brazil, that can reach up to 2-5 feet in height. It boasts an array of ornamental foliage in silver and blue hues, as well as white, off-white, blue, lavender and purple flowers.

This plant requires regular watering and should never be allowed to dry out between waterings. It performs best in shade or semi-shade, and will appreciate some kind of humidity system if kept in dry indoor conditions. Fertilize regularly with a water-soluble fertilizer to keep your Calathea looking its best.

In USDA zones below 10, grow as a houseplant or seasonal container specimen. If you do need to overwinter your Calathea, make sure the pot it is in has good drainage and that you place it in a warm, lightly shaded area. Make sure not to overwater it during this time, as this could lead to root rot. Move the plant back outside during spring and summer.
