Why did my roses change from orange to red?

In 2015 they were orange in 2016 they didn't even bloom and this year they are a deep red.

  • this might be the reason
    It is common practice for rose growers to graft a desired rose variety onto a rootstock of a different rose. Grafting allows growers to produce more plants in a shorter time and get them to market faster.
    Rootstocks are chosen to impart a particular growth habit, increased winter hardiness, vigorous growth and stronger establishment to roses that possess outstanding ornamental characteristics (flower size, color, number, fragrance, growth habit, foliage). Grafting makes it possible for us to enjoy roses that otherwise might not be winter hardy in our climate or that grow so weakly only experienced and well-equipped rosarians can care for them properly.

    So, you may have had an orange rose grafted to a red and over time, the orange part didn't thrive.

    Unless you're the Queen of Hearts, I agree. You've got a red rootstock.
