Scientific Name	Phaseolus Vulgaris
Height	2–3 feet
Soil Type	Well-drained soil
Maintenance Level	Average (lesser than pole beans)
Sun/Shade Preference	Full sun exposure
Watering Needs	Consistent watering

The bush beans further have different types of green beans, including Derby, Roma II, Royal Burgundy, Tendercrop, and Blue Lake, among others.
