Them look pretty nice for potted plants. Definitely a major difference in color. I would say the diffence is purely genetic IF they all had been in the same pot or small area in the ground. Hard to tell as any variation in that soil could exist and since they cant intermingle the feeder roots or have rain mix the soil's nutrients enough for both to get some of the exact same soil, it is just not a positive identifier. Heck, the neibor's dog could have came and peed in one pot but not the other. Just my opinion. Not the most experienced seng grower here by far but have been growing gardens and potted gardens for a lot of years.
That one with the extra leaflets is pretty cool. They all look nice.
