, a notorious insect pest known for its destructive feeding habits. With a voracious appetite, Japanese beetles pose a significant threat to various plant species, including ornamental flowers, fruit-bearing trees, and agricultural crops. Their indiscriminate feeding behavior can cause extensive damage to the foliage of ornamental plants, compromising their aesthetic appeal and overall health. This widespread recognition of the Japanese beetle's impact underscores the importance of effective pest management strategies to protect ornamental gardens and landscapes from infestation.
The term
The term ''ornamental plant'' is used here in the same sense that it is generally used in the horticultural trades, in which they are often just called "ornamentals". The term largely corresponds to 'garden plant', though the latter is much less precise, as any plant may be grown in a garden. Ornamental plants are plants that are grown for display purposes, rather than functional ones. While some plants are both ornamental and functional, people usually use the term "ornamental plants" to refer to plants which have no value beyond being attractive, although many people feel that this is value enough. Ornamental plants are the keystone of ornamental gardening, and they come in a range of shapes, sizes, and colors suitable to a broad array of climates, landscapes, and gardening needs.
Some ornamental plants are ''foliage plants'' grown mainly or entirely for their showy foliage; this is especially true of houseplants. Their foliage may be deciduous, turning bright orange, red, and yellow before dropping off in the fall, or evergreen, in which case it stays green year-round. Some ornamental foliage has a striking appearance created by lacy leaves or long needles, while other ornamentals are grown for distinctively colored leaves, such as silvery-gray ground covers and bright red grasses, among many others.
Other ornamental plants are cultivated for their blooms. Flowering ornamental plants are a key aspect of most gardens, with many flower gardeners preferring to plant a variety of flowers so that the garden is continuously in flower through the spring and summer. Depending on the types of plants being grown, the flowers may be subtle and delicate, or large and showy, with some ornamental plants producing distinctive aromas. Ornamental plants are beneficial.
Ornamental grasses
Ornamental grasses and grass-like plants are valued in home landscapes for their hardiness, ease of care, dramatic appearance, and a wide variety of colors, textures, and sizes available. Many ornamental types of grass are
true grasses (Poaceae), however, several other families of grass-like plants are typically marketed as ornamental grasses. These include the
sedges (Cyperaceae),
rushes (Juncaceae),
restios (Restionaceae), and
cat-tails (Typhaceae). All are
monocotyledons, typically with narrow leaves and parallel veins. Most are herbaceous
