Gregor Mendel used pea plants for his hereditary experiments
Controlled
Mendel carefully designed his experiments and the peas he used.

Mendel used the mathematics in his experiments. He found the ratio of the pea plants who were tall to who were short if every generation and gave the law of inheritance.
They were used by Gregor Mendel to discover the basic laws of genetics.
Mendel is famous for his work with pea plants. These experiments led to the Law of Segregation and the Law of Independent Assortment. Several different pea-plant traits were used in his experiments, including seed type and flower colour.
Mendel kept careful records and used statistical analysis. He did other stuff too, but those are the careful parts.
Gregor Mendel conducted experiments on pea plants, specifically the garden pea plant (Pisum sativum). Mendel used pea plants to study the inheritance of traits and establish the principles of modern genetics.

you tell me
Mendel used pea pod plants for his early experiments. See http://www.mnsu.edu/emuseum/information/biography/klmno/mendel_gregor.html
Mendel studied plant inheritance.
