This is a rare plant. These are young plants that are fully rooted and will develop the fenestration as the leaves age.
This is an easy plant to grow, especially those who forget to water plants. Allow the monstera to dry out then water well. Place it in the shade or bright indirect light. Direct sun will burn the leaves. This plant will make a beautiful floor plant and can be easily rooted into a moss pole. Root nodes will develop on the stems making it easy to propagate.
Your plant will arrive carefully packaged in nursery pot in the size you requested.
