Asian Winged Bean Seedling

Tried Asian Winged Beans this year. They were slow to germinate. The advice on the pack said to soak the seed for two hours and plant them. So I did and they didn't come up for WEEKS. I thought I got bad seed and figured that the seeds had rotted by then, but just as I was about to dig them up they finally came up. I looked elsewhere on line and it seems you are supposed to soak them for 24 hours, not 2. Anyways, here is what the seedlings look like:

This is from about two weeks ago, I will have to get a more detailed and updated picture soon.
