Alphabetical List of Perennial Flowers: Perennial Flowers Q-T

The Alphabetical List of Perennial Flowers continues here with those which begin with the letters Q-T. As with the previous entries on this list, I will briefly describe the most commonly-available species of perennial flowering vines, shrubs, trees, and groundcover. In subsequent posts, I will attempt to further analyze some of these species in great detail, as they warrant further investigation. For this list, however, I am picking and choosing select species - there would be 20,000 different types of perennial daisies on this list if I tried to include every perennial flower! Nevertheless, the list is an evolving work in progress, where more species will be added as I discover them.
