Can anyone tell me if the seedlings of Rainbow Chard will all be Red to start out and then turn to their actual color as they grow larger? Or should I assume they will all end up Red Swiss Chard. Some do look Pink, but most are Red. I did a trade here on the seed exchange with two people and all are looking to be the same color so far. They are pretty tiny, about 1 1/2 inches up so far.
