When you see "Miniature" next the word "class" on the rose page, you are seeing the definition of the class the rose breeder decided to assign to the rose.  Each class of rose has similar characteristics.  For example, when a rose is classified as a miniature rose, the class is determined by the size of the bloom, not the size of the plant. A miniature rose can be less than 1 foot tall or as much as 4 or 5 feet tall...and that's not counting the climbing miniature roses when can grow up to 10 feet or more.

Most Hybrid Tea roses, another class of roses, have blooms that generally are born solitary, while floribundas are cluster-flowered plants.  I think you are referring to roses in these classes when you are asking about "standard size" bushes.

If it is the striping characteristic that has drawn your eye and made you want to have this kind of rose in your garden, you can do an advanced search on HelpMeFind for striped roses which are hybrid tea or floribunda roses.  The search will give you a list of links to rose pages of striped roses that are not classified as miniature roses.
