Many beans are summer crops that needs warm temperatures to grow; peas are an exception. Legumes are capable of [[nitrogen fixation]] and hence need less fertiliser than most plants. Maturity is typically 55–60 days from planting to harvest.<ref>{{cite book |last1=Shurtleff |first1=William |url=https://books.google.com/books?id=zWW4AQAAQBAJ&q=bean+maturity+55%E2%80%9360+days&pg=PA452 |title=Early Named Soybean Varieties in the United States and Canada: Extensively Annotated Bibliography and Sourcebook |last2=Aoyagi |first2=Akiko |date=1 October 2013 |publisher=Soyinfo Center |isbn=9781928914600 |access-date=18 November 2017 |via=Google Books}}</ref> As the pods mature, they turn yellow and dry up, and the beans inside change from green to their mature colour. Many beans are [[vine]]s needing external support, such as "bean cages" or poles. Native Americans customarily grew them along with corn and squash, the tall stalks acting as support for the beans.<ref>{{cite book |last=Schneider |first=Meg |url=https://books.google.com/books?id=6O4sOoTqV60C&q=native+americans+corn+beans+squash&pg=PA114 |title=New York Yesterday & Today |publisher=Voyageur Press |isbn=9781616731267 |page=114 |access-date=18 November 2017 |via=Google Books}}</ref>

More recently, the commercial "bush bean" which does not require support and produces all its pods simultaneously has been developed.<ref>{{cite web |title=The Germination Of a Bean |url=https://www.microscopy-uk.org.uk/mag/artdec13macro/Gerhardt_Final.pdf |url-status=live |archive-url=https://ghostarchive.org/archive/20221009/https://www.microscopy-uk.org.uk/mag/artdec13macro/Gerhardt_Final.pdf |archive-date=2022-10-09 |access-date=18 November 2017 |website=Microscopy-uk.org.uk}}</ref>
