Draw an E$-$R diagram for the scenario below.

Green Thumb Garden Center specializes in rare and exotic plants, offering a variety of species $($e$.$g$.,$ orchids, ferns, succulents, and carnivorous plants$).$ Each plant is uniquely identified by a plant number and has a description, asking price, care instructions, and photos. Green Thumb works with a diverse set of customers, referred to as gardeners, who both purchase plants from and sell plants to the nursery. Some gardeners only purchase plants, others only sell, and some do both. Each gardener is identified by a gardener number and has details such as name and contact information recorded. When Green Thumb sells a plant to a gardener, the transaction details recorded include the commission paid, the actual selling price, sales tax, and the date sold. Conversely, when purchasing a plant from a gardener, Green Thumb records the purchase cost, date purchased, and plant condition at the time of purchase.
