Answer 3

Actually, insects often CAN see their beauty - just not in quite the same way that we can see it. While they may not understand "beauty," they often are programmed to be attracted to certain colors and shapes of blossoms. As you've pointed out, these are often flowers with little or no scent, so *something* has to attract pollinators, and characteristics such as shape and color (including wavelengths in the ultraviolet range that an insect can see but we can't) are often the motivator for an insect to visit a blossom and do its work.

Answer 4

The showiest flowers have been selectively bred by humans for the traits that appeal to us, such as bloom size and color. Growers have cultivated them for generations to emphasize these characteristics. In the process, fragrance has been lost. That's why the lovely hybrid tea roses have no smell at all.

If you want truly fragrant flowers, look for the older varieties like the basic, old-fashioned lilac (Syringa vulgaris) or the original "tobacco" flower (Nicotiana sylvestris).
