Prosperity
4th-level abjuration
Casting Time: 1 action
Range: Touch
Components: V, S

Healing energy washes over a touched creature, filling it with vitality. The target heals 4d8 hit points
If you target a plant creature or a magical plant, the spell heals 8d8 hit points of damage.
If you target a nonmagical plant that isn’t a creature, such as a tree or shrub, it instantly doubles in size growing with tremendous speed.
At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the healing effect increases by 1d8 for each slot level above 4th if cast on any normal creature, but it heals 2d8 for each spell slot above 5th if cast upon a plant creature or magical plant.
Thoughts?
Throat Punch Games 
I think the spell name implies the spell is about wealth instead of healing.
Fair, but I was thinking anti-blight.
