Russ Crow from Illinois was kind enough to send me some beans, including two cultivars of lima beans.
He has an informative internet site:
This was my first time growing lima beans. It was hard to believe I could grow them up here in Denmark, when I read they prefer they heat of the southern USA. But I’m fond of testing new crops. I grew both cultivars in open ground (after a start indoor) and in greenhouse.
Both cultivars grew well in the greenhouse, though Purple Eye was considerably more productive than Ganymede.
In open ground they grew no higher than bush beans.
Purple Eye produced four pods, Ganymede none.
