What type of organism did Mendel use in his genetic experiments

Pea Plants--

The genetic experiments Mendel did with (pea plants) took him 8 years (1856-1863) and he published his results in 1865. During this time, Mendel grew over 10,000 pea plants, keeping track of progeny number and types. Mendel's work and his laws of inheritance were not appropriated in his time.
