Grandiflora rose bushes (originally a cross between the hybrid tea and floribunda rose types) are tall plants that readily produce clusters of blooms. The 'Queen Elizabeth' rose was the first to merit the designation of "grandiflora", and I have quite a few unnamed seedlings that I have grown from one of my open-pollinated (very likely "self" pollinated) 'Queen Elizabeth' roses. As you can see in the photos below, the clustering habit is very evident in two of the seedlings.

Update of September 16, 2017: The rose bush that produced the bloom cluster shown in the photo on the right (above) was looking really nice today. The growing season is tapering off, and fewer clusters are forming, and more slowly at that. With a rainy week ahead, I thought it would be wise to take a photo of the rose today, while it still looked good. This grandiflora-like seedling, now 5 feet tall, will be 8½ years old next month --
