Gardeners grow two different types of plants essentially, annuals and perennial plants. The yearly plant grows from a seed; flowering traces as well as the mother plant dies after the new crop of seed has grown.
The perennial plant doesn’t have a life span that’s limited to a year unless it’s grown from zone. As an example, the tulip bulb is a perennial plant when grown in the Netherlands, but in much of america, the tulip bulbs decrease and will not flower again in several States, so that tulips are planted afterwards as an annual-not to go back the next year. The environmental factors of heat and humidity restrict the growing and planting of tulip bulbs in a lot of the United States as a perennial plant.
Elephant ear bulbs can be grown as a perennial plant in warmer climates where the elephant ear bulbs grows in size every year to form enormous clumps. Elephant ear bulbs when planted in Northern States such as New York won’t survive outside temperatures of ice and snow and must be grown as a yearly unless the elephant ear bulbs are dug up and stored within the house.
From these perennial bulb cases, it can be shown how significant temperature variables are in plant survival. Other variables of the environment are significant, such as light intensity. Yucca plants and agave plants thrive in warm, dry, sunny conditions, and if both of those plants are grown in low light, the decline begins that eventually leads to plant death.
Desert plants like agave plants, yucca plants, and aloe plants may survive in the arid areas of the hills and heat, drought, and extreme sunlight that other plants couldn’t tolerate. The yucca, agave, and aloe plants couldn’t survive tropical jungle humidities and color.
These are extremely adaptable to any environment imaginable, from rocky peaks on arctic-like mountain tops, to the heavy shade of tropical rainforests, ferns thrive. As a nursery plant, ferns are grown as bedding plants in sun or shade or as delicate indoor potted fern plants like the lacy maidenhair fern, Adiantum peruvianium, and the foxtail fern, Asperges meyerii.
Groundcover perennial plants are important in controlling erosion and in reducing soil evaporation. Some groundcover plants form clumps and many others, such as ivy, form vines that can quickly grow to cover uphill bare spots or cover buildings and walls. Ivy grows rampantly once recognized and is popular to use in planters and hanging baskets. Iron plant, Aspidistra lurida, develops well as a shade plant and a few aspidistra forms are covered with white dots on the waxy green leaves; others are variegated with white stripes, Aspidistra elatior’Variegata.’ Palm bud, Curculigo capitulata, grows well as a shade plant near pools. Dwarf mondo grass, Ophiopogon japonicus nana, is an superb liriope-type groundcover that aggressively crowds out weeds and develops in white or green forms for landscape contrasts. The creeping fig vine, Ficus repens, quickly covers walls and can cover ground areas which are bare. Ficus repens, fig vine, can quickly send out leafy shoots which develop a foot weekly. Liriope groundcover perennial plants are among the most popularly grown since they’re colorful, compact, clean growing and grow in many sizes. The hottest liriope cultivars are Liriope muscari ‘Big Blue;’ Liriope muscari ‘Royal Purple;’ Liriope muscari’Super Green Giant;’ and Liriope muscari’Variegata.
Flowering bush hydrangea perennials are native plants into the United States, and lots of new hydrangea cultivars are developed in vivid colors of blue, red, white, purple, and pink. Hortensia bushes shed their leaves throughout the winter, but spring back to life in the spring, covered with blossoms.
Flowering vine perennials are developed to cover fences, trellises, and walls-some with evergreen foliage, others with blossoms with a bonus of several colours, such as red, coral, blue, purple, pink, white, and yellow. Carolina jasmine, Gelsemium sempervirens, covers the whole vine with bright yellow flowers, which are fragrant and quick growing. Confederate jasmine, Trachelospemum jasminoides, blossoms with white or yellow blossoms, perfumed like other sweet jasmine vine perennials. Bleeding heart palpitations, Clerodendron thomsoniae, flowers vivid red, heart-shaped blossoms and climbs as a vine rapidly for privacy screens. Coral vines, Antigonon leptopus, are famous in the South for heart-shaped leaves and delicate delicate blossom clusters of white or pink. Coral vines are famous locally in Florida as the Tallahassee vine.
The butterfly bush is sweetly scented and easy to grow as a perennial bush or hedge. Butterflies swarm on the flowers in summer and autumn seasons which are tough and can readily become established underneath pine trees in thickets, some are recorded to have persisted for over 40 years in 1 place. Important flowering butterfly bushes flower in red, purple, pink, white, and yellow. The major cultivars grown are Buddleia lindeyana, Buddleia davidii’Bonnie,’ Buddleia davidii’Pink Delight,’ and Budlleia davidii’White Profusion.
Ornamental grasses have secured an important place in the landscape garden. As a bedding plant, ornamental grasses like black fountain grass, Egyptian papyrus, lemon grass, Pink Muhly grass, Red fountain grass, Umbrella bud, Tricolor society garlic, Northern sea oats, Pampas grass, Cortaderia selloana, and Japanese silver grass have discovered valuable placement in office construction landscapes.
Angel trumpet plants (Datura) are extremely desirable to grow in warm climates. The trumpet blossoms open as fragrant one foot blossoms, drooping as the as the afternoon progresses. Flowers of many datura, angel trumpet plants, cover the tree all summer and fall in a blaze of colour: red, pink, white, yellow, orange, purple, etc.. These datura (angel trumpet) plants are easily hybridized into several appealing interesting color combinations, known technically as’Brugmansia’ x’candida.
