We're developing our school grounds and are looking for donations of plants to help us. We want to plant up some tyres so looking for shrubs or perenials that dont require a huge amount of maintainance. Also wanting to make some small world play tyres, turning them into various 'lands' such as for dinosaurs so looking for suitable plants to help with these imaginary worlds such as succulants, ferns, grasses etc. We will also be planting a sensory garden over the next month or so, so looking for any ideas for that. maybe lambs ear, poppies, galic, herbs etc. Any help would be very much appreciated.
