The invention relates to a planting device, in particular to a device for planting artemisia vulgaris. The device comprises a supporting frame, a water spraying pipe is transversely arranged on the top of the supporting frame, multiple first nozzles are communicated with the bottom of the water spraying pipe, a water inlet pipe is communicated with the water spraying pipe, multiple planting baskets are arranged transversely on the supporting frame from top to bottom, multiple sliding grooves are formed in the top and bottom of each planting basket respectively, multiple wavy guide pipes are vertically arranged in each planting basket, second nozzles are arranged directly above the tops of the guide pipes in the planting baskets on the top layer and communicated with the water spraying pipe, and the amount of water sprayed out by each second nozzle is greater than the amount of water sprayed out by each first nozzle; the two ends of each guide pipe are slidingly connected to the interiors of the sliding grooves in the top and bottom of the corresponding planting basket respectively, a driving mechanism is disposed at the junction between each guide pipe and the corresponding slidinggroove, each water storage tank is communicated with the bottom of the corresponding guide pipe, a water outlet hole is formed in the bottom of each water storage tank, and a rotating mechanism is connected between each water storage tank and the corresponding guide pipe. The device can solve the problem that since planting racks are adopted for planting artemisia vulgaris in the prior art, soilis loosened inconveniently.
