1-level Conjuration
Grasping weeds and vines sprout from the ground in a 20-foot square starting from a point within range. For the Duration, these Plants turn the ground in the area into Difficult Terrain. A creature in the area when you cast the spell must succeed on a Strength saving throw or be Restrained by the entangling Plants until the spell ends. A creature Restrained by the Plants can use its action to make a Strength check against your spell save DC. On a success, it frees itself. When the spell ends, the conjured Plants wilt away.
