You cause a plant of from the tiniest size to the largest tree to temporarily grow to support an immense limb and swing out at a target in range. The plant must be in spell range and has a reach of 10'. Make a melee spell attack against the target. If the attack hits, the target takes 4d6 bludgeoning damage. If the target is a creature of large size or smaller you may also attempt to push that creature 15 feet in any direction subject to a Dexterity saving throw. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 2d6 for each slot level above 2nd.
