Background Germination is when seeds undergo the process of turning into plants when the right conditions are given. These conditions include water, oxygen, temperature (some seeds may need a warmer/cooler temperature depending on the type of seed) and some seeds may also need a specific amount of light to germinate (https://extension.illinois.edu/gpe/case3/c3facts3.html). Seeds have an outer shell (seed coat) surrounding them. Inside the seed coat is the embryonic plant and the seed lives off of it’s nutrients until proper conditions as listed above are received and the process of germination begins.

The binomial nomenclature is Phaseolus lunatus (https://myfolia.com/plants/1917-lima-bean-phaseolus-lunatus) The seeds ranged from being as small nickel to as big as a dollar. The seeds were oval in shape and white. Lima beans are dicots and the germination of lima beans averagely are in between 5-12 days and are fully matured approximately around 111-148 days , total growing days is 154 (https://myfolia.com/plants/1917-lima-bean-phaseolus-lunatus) Historians are unsure wether lima beans originated in peru or guatemala. Spanish explorers found varieties of lima beans growing throughout south america, central america and the carribean. Lima beans can withstand humidityy and tropical weather better than most beans. http://www.whfoods.com/genpage.php?tname=foodspice&dbid=59) Lima beans require soil temperature to be 60°F. Lima beans germinate best in soil with a pH of 6.0 and 6.8 and air temperature approximately between 60°-72°F. If soil moisture is too high seeds have a possibility of cracking and not germinating. Soil must always be evenly moist and never have excess amount. Depending on the type of lima bean the depth they are planted at varies but sow lima beans should be planted at 1.5-2 inches deep. When planting should be cautious that they are not planted where there is nitrogen high soil or where green manure crops have grown. If the beans are planted in an area with this they will still produce green foliage but only a few beans rather than the typical amount it could produce.
