TREES • Trees- largest plant components of garden and landscapes. • They differ in stature, branching, habit, girth of trunk, and branches, canopy structure outline and crown shape, color of foliage, texture, glaze, shape and size. • Trees are grown for shades, flowers etc. • As avenue they are planted along roadside avenues and central avenues • ex. Ficus religiosa, Delonix regia, Coral wood tree, rain tree, bird cherry, tree techoma, bauhinia, asokam, Ylang ylang,parijatham, golden champa, elengi, Polyalthia longifolia, bauhinia
• Trees are perrenial plant with a clear cut elongated stem or trunk supporting branches and leaves • trees are very fascinating because of their graceful appearance and the abundance of bloom. • They are grown for their economic importance or aesthetic value or both. • The cultivation of trees for their aesthetic or recreational value is known as arboriculture. • Trees should be planted carefully and thoughtfully for the benefit of height, shade, colour and vertical emphasis. • They also plays an important role in controlling air and noise pollution in cities. • Trees form the main framework of the garden. • Some trees produce attractive and beautiful flowers including fragrant flowers some trees have attractive foliage • some trees are known for their peculiar shape or form which is used as specimen trees. They give a mass effect and beautiful look to the localities. • The place where trees are grown either for landscaping or for scientific study is known as arboretum.
• FEW EXAMPLES OF TREES ARE AS FOLLOWS:- • Cassia fistula (the indian laburnum) • Lagerstroemia speciosa (pride of india) • Erythrina variegata (indian coral tree) • Saraca asoca (sita ashok) • Cochlospermum religiosum (yellow silk cotton tree)
MASS EFFECT OF TREES
•THE REASONS FOR PLANTING TREES ARE: To frame buildings and create vistas • To add the appearance of the home • To shade the house, terrace and garden seats and give a play of light and shadow on the lawn • To add interest to the skyline • To soften the harshness of roof lines and angles • To hide undesirable objects • To establish boundaries • To provide protection from wind • Smaller trees would be used to serve as a transition to larger trees to shrub biomasses. • To line avenues and streets and encourage bird life.
IMPORTANCE • 1. ENVIRONMENTAL VALUE • Prevention of soil erosion • plants with shallow fibrous root systems are effective to prevent soil erosion. • •Turf grasses are also effective in preventing soil erosion. • •The deep roots of trees help hold the soil tight. • •Trees also absorb some of the nutrients in the soil that would otherwise be washed away.
2.FUNCTIONALAND ARCHITECTURAL VALUE :- Can cater to the need for privacy, Protection from glare or direct sunlight into windows, or shade. Trees as hedge - Acacia farnesiana, Erythrina, Gravillea robusta,Inga dulcis, Polyalthia longifolia, Pongamia glabra,Tthevetia nerifolia
CLASSIFICATION From the floricultural point of view, trees are classified into two groups, namely, foliage trees and flowering trees Foliage trees: the trees planted for their showy ornamental foliage are known as foliage trees. Adansonia digitata, Ailanthus excelsa, Albizzia lebbek, Alstonia scholaris,Aanthocephalus cadamba, Araucaria cookii, Azadirachta indica, Dalbergia sisoo,Eeucalyptus, Ficus bengalensis, Ficus elastica, F. religiosa, Juniperus Sp., Melia azedarach, Pinus sp., Pongamia glabra, Putranjiva roxburghii, Salix babylonica, Terminalia arjuna, Thuja orientalis, etc. Are the examples of foliage trees. Flowering trees: the trees planted for their showy ornamental flowers are known as flowering trees. Amherstia nobilis, Bauhinia sp., Bignonia megapotamica, Butea monosperma, Callistemon lanceolatus, Cassia fistula, Cassia grandis, Cassia nodosa, Chorisia speciosa, Erythrina indica, Jacaranda mimosaefolia, Lagerstroemia indica, Plumeria alba, Peltophorum ferrugineum, Rhododendron sp., Saraca indica, Tabebuia rosea, etc. Are the examples of flowering trees.
DECIDUOUS TREES • Deciduous refer to trees, which seasonally shed their unnecessary parts especially the leaves from their structure. • Deciduous trees are adapted to tolerate the cold and dry weather conditions by shedding their leaves seasonally • majority of the trees shed their foliage at the end of their typical growing season.
EVERGREEN TREES Evergreen tree’s foliage persists throughout the year. •No seasonal leaf shedding, they shed their old leaves throughout the year •favored in warm temperate climatic conditions
COLUMNAR TREES • Columnar trees are tall and very thin, with upright branches. Their vertical shape adds height and also provides great screening without taking up much room in the landscape. Eg. Columnar apple – malus spp. They are good for planting in narrow side yards. They are good on either sides of an entrance. E.G.: Polyalthia pendula [false ashoka] • columnar peach – prunus persica ‘crimson rocket’ ,columnar apple – malus spp
PYRAMID OR CONICAL SHAPED TREES • We often think of christmas trees as the classic pyramidal tree, but the shape applies to deciduous trees as well. Pyramidal trees are wider at the bottom, with a main center trunk and horizontal branches. The branches may start at ground level or higher up the trunk. Conical trees are similar but are usually more slender and bullet-shaped. These trees are very dramatic and need space to reach their full width
VASE SHAPED TREES • Vase shaped trees are just what they sound like: a central trunk that branches into an upright arching shape that’s widest at the top. Vase shaped trees are graceful and perfect for lining walkways. Because they offer both shade and head room .
ROUND OR OVAL SHAPED TREES • These trees are upright, with a central strong trunk that branches into a dense round or oval-shaped crown. They make strong shade and may have such dense foliage that the branches are concealed.Have almost clipped appearance & add formal touch to the landscape. Eg. Thuja occientalis [northern white-cedar or eastern arborvitae]
SPREADING/ OPEN SHAPED TREES • These trees have an open, irregular shape that may be wider than it is tall. Some are towering skyline trees, and others are smaller, bushy specimen trees. Eg. Cherry, mango, sapota
WEEPING TYPE • A good choice for specimens are trees with a weeping shape, where the branches droop down and sweep the ground. Eg. Weeping cherry – Prunus subhirtella ‘pendula’
GULMOHAR • ➤Common name: gulmohar • ➤ scientific name: Delonix regia • ➤ nature: deciduous • climate: tropical or near-tropical climate • height: 5-12 m • ➤ texture: soft and light • ➤ shape and color: green and flaccid when young and turn dark-brown and woody • ➤ foliage: dense, fern-like leaves • soil type: open, free-draining sandy or loamy soil enriched with organic matter • ➤ uses: ornamental
BARNA ➤Common name: barna ➤ scientific name: Crateva religiosa ➤nature: deciduous ➤climate: ➤height: 30-40′ texture: ➤shape and color: green ➤ foliage: ➤ soil type: ➤uses: dyeing, medicines
OLEANDER • ➤Common name: oleander • ➤ scientific name: Nerium oleander • nature: evergreen shrub • ➤climate: subtropical and tropical areas • height: 2-6 m • ➤texture: thick and leathery • ➤shape and color: grayish bark. Dark-green • foliage: grow in clusters • ➤soil type: tolerates a variety of soil • uses: ornamental gardening
BOTTLE BRUSH • Common name: bottle brush • Scientific name: callistemon • nature: evergreen, shrubby tree • climate: temperate regions • height:10 to 15 feet • texture: fury • shape and color: red flower spikes • foliage: crown is rounded • soil type: well-drained, sandy soil. Also grow in clay or loam • uses: ornamental landscaping
GOLDEN RAIN TREE • Common name: golden rain tree • scientific name: Cassia fistula • nature: deciduous • Climate: tropical and subtropical areas • height: 10-20 m • texture: • shape and color: • foliage: • soil type: • uses: ornamental plant and is also used in herbal medicine
JARUL • Common name: jarul • scientific name: Lagerstroemia speciosa • nature: deciduous • climate: tropical and subtropical areas • height: 20 metres • texture: smooth, flaky bark • shape and color: oval to elliptic • foliage: • soil type: range of soils • ➤uses: chemical compounds
CHIR PINE • CHIR PINE • scientific name-pinus roxburgh • family-pinaceae • uses- chir pine is widely planted for timber in its native area, being one of most important trees in forestry in northem india and nepal. For local building purposes, the wood of this tree is the least preferred, as it is the weakest and most prone to decay when compared with other conifers
