Artificial flowers/plants and till (Harbourland ME14)

I work at a special needs school, and next term we are learning about growing. I would like to change the role play area into a florist / garden centre, so would be grateful to receive any artificial flowers/ plants, plastic plant pots, watering cans, florists ribbon, etc - anything you can think of that we could use! Also, we would love a till if anyone has one that we could re-home.
We will also be planting outside, so any spare seeds or young plants that we can nurture would be amazing! (Obviously these need to be safe for children!)
Thank you so much!
