Provided herein are compressed plant material assemblies, as well as apparatuses and methods for forming compressed plant material assemblies. A compressed plant material assembly includes plant material such as smokable cannabis plant material. The plant material is compressed into a form such as a ball, with a wick disposed partially within the ball of compressed plant material. The apparatus includes a base, a lid, and a plunger. The base includes a mold cavity with a major portion for holding the plant material, and a minor portion for holding the wick partially inserted in the plant material. The lid, when applied to the base, does not enclose the major portion of the mold cavity, such that the plant material can be compressed with the plunger.
