I planed rose bushes of six varieties and they died off, and this year they bushes came back but all red, why?
Answers:
They froze at the graft which is right above the ground and they have reverted to the grafted root stock which is a type of wild rose. It won't give good roses,is rampant, and you need to get rid of them. I sell roses and Jackson and Perkins has a new type of rose called a new generation. J&P has gotten it so the top part above ground is the same as the root stock so there is no graft to freeze. J&P has about 30 types of roses in the new generation line but are adding more and more (colors, climbers, teas...that sort of stuff) and in a few more years they tell me that over half of all their roses will be new generation. No more need to worry about freezing. If you do buy the grafted roses, make sure you cut them back, put chicken wire around the stems to protect against mice, put a bushel basket over the stems and cover with straw. The ground won't freeze nor will the graft. Good luck.

Make sure they get lots of water. Roses love water. Also lots of sun but water is most important.

You planted them too close together and they mixed.
Save what you like, and replant new, and further apart.
this same happened it to me . just water it .
Most varietys of rose originate from the red rose. Some are grafts, so if you cut them back beyond the graft they will revert to the root stock of the plant, which is almost always a red variety. They do this because the red root stock is more robust and supports less robust varietys. you may have to start again with new plants and ask the nursery if they are grafts and where the graft is so that you dont trim them past it. Roses are generaly heavy feeders so a good supply of blood and bone is good at the start of the growing season. Also there are many good liquid rose foods on the market that will promote good healthy growth.
yeah willroch is right - it looks very much as the root stock. so inspect the plants, find whether all the grafted part died off. if there is still some part of it alife, cut the root stock so that the grafted variety has a chance. - that is the last hope. but i bet you lost them
