Plants of small to medium stature, giving mass flowering and attractive foliage over a long period of the year, should be chosen for a roof garden.
Hard and drought tolerant ornamental plants are also good.
Use of herbaceous annual flowering plants can give mass flowering, thereby creating a riot of colours.
Bulbous plants can be included for their colorful flowers and foliage, produced throughout the year.
Only small and medium shrubs of exquisite floral or foliage beauty should be chosen for the roof garden.
Small climbers, both annual and perennial may conveniently be placed along posts and pillars as well as on arches on the roof.
A good bed for roses can be prepared by constructing an 8 cm thick and 40 cm high brick wall beside the one at the boundary of the roof garden and 30-40 cm away running parallel to it.
The space between these two walls may be filled up with the same soil mixture used for the roof garden for planning roses.
Besides roses, shrubs and small trees may be accommodated in this bed.
Garden features, like lawn, edge, flower beds, rockery, lily pool, fountain, topiary, plant houses, statue, sundial, mini-temple, garden light, music set-up, aquarium, mini-zoo, etc. may be installed to make the roof garden attractive and beautiful.
Arch and bower may be constructed where there is no overhead structure.
