I am the Gardener Hero, summoned from another world

Through magic, you’ve been summoned to a new world!
You’re the hero who must save the kingdom from the demon lord!
But it turns out it’s not that simple—because you don’t have any heroic abilities!
Except for one...
You’re a gardener...
But you can’t grow fruits and vegetables...
Instead... instead, you can bring heads to life and grow them in a flower pot!
Cool, isn’t it???
