Leonardo da Vinci (1452–1519) is recognized for his curiosity, imagination and sublime artistic ability.
In the years after 1505 Leonardo da Vinci produced a number of delicate drawings of plants and flowers, mostly drawn with a sharpened red chalk on paper coated with a delicate pale red preparation, itself probably composed of ground red chalk.
Friedrich Froebel developed nature walks for each children to experience the natural environment and see plants and flowers growing in nature.
