Lima beans originated in South America and around 1300 moved further up to North America. In the 1500's Lima beans made their move to Europe. As the beans were shipped around the world their origin was labeled on the package. Earning them the name- Lima-Peru or Lima beans! Now why Southerners call them butter beans that's another story I'll have to look up one day.
Figuring out when to pick them and keeping the caterpillars off of them, I've found three different caterpillar varieties on them so far, is the two largest challenges of growing them so far. Despite this, I picked a whole "mess of 'em" and there are a whole bunch left on the bush. They've grown well in our fall weather, which varies between 65 to 85 degrees.
