Harry Potter - Secrets of Hogwarts

This spell channels vitality into plants within a specific area. There are two possible uses for the spell, granting either immediate or long-term benefits. If you cast this spell using 1 action, choose a point within range. All non-magical plants in a 60-foot radius centered on that point become thick and overgrown for 1 hour, turning the area into difficult terrain. These plants can't be used in potions, due to being magically manipulated. If you cast this spell over 1 minute, you accelerate the growth of a single young plant you can see within range, magical or mundane. The plant instantly reaches maturity, but does not exceed a healthy "adult" size.
