I have these flowers in my front yard, and we don't even plant them. Yet they grow. Can y'all tell me why this weird phenomenon happens? They are daffodils, but then something weird happens. After the daffies die, tulips grow. Yet they are only pink. Only pink! Can y'all tell me why this happens?

Thanks for your info, (if you post anything),
Empress!
