The growth rate and leaf color of Orbifolia will vary greatly depending on soil type, sunlight, temperature and other factors. A few leaves are often trimmed prior to shipping to reduce transpiration and travel stress.
When you receive your new Calathea, there is no need to worry about planting right away. Your new plant can be stored for a while by simply placing it in a bucket with about a half inch of water in the bottom and moving it to a shady location. You can then add some mulch to keep your plant standing upright. The mulch will also supply nutrients while in storage. This will give you plenty of time to select the ideal location for your new Calathea.
