FWIW, Kale is super easy to grow and produces a ton of edible foliage. 2 mature plants is way more than enough for most families. We have 2 mature plants and 6 young ones. In about a month we'll be giving away kale to everyone we know. Beans and Peas are finally starting to do well and it's probably going to be really hot next week, which will likely kill them. We get a big handful of peas and another of beans about once a week.
