Numerous species, such as deer, rabbits, squirrels, turtles, and lizards, rely heavily on flowers for sustenance. Aphids, spider mites, sawflies, and more insects also feed on flowers.
The consumption of flowers by deer and rabbits frequently causes problems for gardeners. According to Better Homes and Gardens, odoriferous chemicals, such as fabric softener sheets and moth balls, and scaring deterrents, such as radios and noisemakers, are common deterrents. Ironically, morning glory blooms are frequently employed as deer repellents. The Humane Society of the United States adds that rabbits are also a source of frustration for gardeners, but they may often be deterred using barriers or chemical repellents. Flowers that blossom in early spring are an essential part of squirrels’ diets, as few other food sources are available.
Many aquatic turtles eat the occasional flower that falls into a stream, although a few of land-dwelling tortoise species largely rely on flowers. According to the Tortoise Trust, red-footed and yellow-footed tortoises, as well as numerous Mediterranean tortoise species, are particularly fond of flowers.
Flowers, including dandelions, roses, and violas, are also consumed by humans. According to the National Center for Biotechnology Information, flowers may be an important source of potassium and other dietary elements.
