Hello, I had noticed an interesting thing about our snapdragons in the garden, they've been there for about 3 years I think, and there have been 3 colours of different plants: yellow, pink and dark red, and the ones that are coming up now in the same place have all of the colours together in the same flower, I mean each flower has all of the colours of the three!
Just curious to now why it happened, if anyone can help?
