1. "Covert" refers to being hidden or concealed, and "candid" refers to being honest or straightforward. These words are good descriptors for a flower because they may refer to the process of the flower blooming or the appearance of the flower. For example, a flower that blooms early in the spring may be "covert" in April, as it is one of the first to appear. Similarly, a flower that has an honest or straightforward appearance may be described as "candid."
2. "As the stir cracks and crazes their branches like enamel"
"Soon the sun's warmth makes them shed crystal shells like"
"Such heaps of broken glass to sweep away like"
