Well, my Blue Jade corn is coming into its own! When ripe and ready to pick, all the kernels turn a dark, dark blue--which lightens up to a cheery royal blue when cooked. So far, I've picked three ripe ears, each of them about the length of my hand. They make a wonderful snack to munch on.
As far as their taste, they are sweet. Not as sweet as the ubiquitous Peaches & Cream sold at every roadside stand, but they are sweet enough to savor. The sad thing is that I only managed one ear per stalk, so my feasting is limited.
