Sells for $10. This came from a tier 1 reptans seed, that I got at the start of the game.
** When prices are listed you should note that this is the price I have at one time in the game sold the plant for. Plants with dead leaves or that are infested with bugs won't sale for as much as plants that are properly trimmed and cared for. It is very possible the plant is worth way more that I have it listed as. Your own plant prices may vary as well form mine. Upgrading your nursery and the discovery of certain magical plants will help your plants sell for more. Please consider the prices stated as only a basic guide to give you a starting point for your own plant picing.
