Ornamental gardening: –

· Plants can be grouped together in various way to give an aesthetic effect. Each such grouping is called as ‘feature’.

· Fence is the outermost boundary. Eg: Prosopis julifera, Casuariua equisetifolia.

· Hedges are useful to divide the garden into section to line the drives so as to direct the visitor to a central object. Eg: Lantana camera.

· Edges are grown along the paths and around the flower buds. Eg: Alternanthera sp., Eupatorium cannabinum.

· The path should be slightly raised over the ground level. It may be laid with gravel (or) brick which are careful painted when it is called a “paved path” covered with broken slabs when it is known as ‘crozy path’.

· Lawn forms the background colour in the garden. Eg: Cyanodon dactylon

· When plants are grown in a row, but not trimmed the feature is called a border.

· Borders are planted to different sps; while hedges are generally planted a single sps.

· The shrub borders may be grown along wall (or) in front of fence of tree, but are not in a row the feature is known as “Shrubery”. Eg: Croton.

· Glass structures are called conservatories (or) glass houses.

· Terristrial orchids grown in soil. Epiphytic orchids grown on branches of trees. Most orchids develop “Pseudo bulbs” for storage of water.

· Pot galleries – on the steps of which ‘potted plants’ are arranged.
