I bought 2 rose bushes, one called Waltz Time and one called Joro. They have been growing very well but I have noticed they have got 7 leaves and no flower buds.
Rose Bushes Not Flowering
The roses could be sending out what is called blind shoots that do not bloom, they just suck up nutrition and do not bloom. Or it could be that something is bothering or stressing the rosebushes. Here is a link to an article for you on this subject: https://www.gardeningknowhow.com/ornamental/flowers/roses/no-blooms-on-roses.htm
Those are two beautiful roses by the way and such a grand contrast in colors! I hope they do bloom for you.
