Hello!, I bought them as seeds and I've never grown collards before so I'm not sure what it really is, many people told me that it's a Brassica, but that's about it we never went any further than that. here are the pictures
It looks like collards to me. Collards are cultivars of Brassica oleracea that have loose leaves. They are very similar to kale. Collard (plant) - Wikipedia
That's a relief!, at first I thought they were something else, after contacting the seller they also told it It's either Georgia collard or something similar to Champion collard, thanks guys!
