The bloom size and age can help me narrow down the choices nicely. It excludes all of the mini-roses and new roses.
The habit is the way the rose grows. Is it a climber or does it stay relatively short? Would you call it bushy all the way from the bottom to the top, or does it tend to grow upright, with "bare ankles" and most of the foliage and blooms at the top? How tall is the rose bush? Do the blooms appear in clusters or singly, one bloom at the top of each cane (or branch)?
