Letter: Beautiful flowers and wonders unseen

Yvonne Kolbenschlag writest:
Not only do flowers have beauty . . . but each kind of flower has evolved to lure a pollinator by producing nectar, a sugar-based substance . The pollinators transfer bits of pollen from flower to flower. According to the head of the plant conservation unit at the Museum of Natural History, Gary Krupnick, plants adjust their nectar production to match the needs of their pollinators. For example, small blue borage flowers can replenish their nectar in two minutes. Agave plants, produce nectar only at night. A recent study found that evening primrose is even able to detect the specific sound frequencies of its bee pollinators and when it does, it makes fresh nectar in three minutes to attract them.

This information comes from the December 2020 issue of the SMITHSONIAN magazine, page 84.
