Roses are one of the important plants that are used in landscaping and for aesthetic values. The concept of landscape roses is in vogue in the West and slowly it is gaining importance in developing countries. Generally, landscape roses are low maintenance roses which bloom continuously in the season, having pest and disease resistance and hardy with large clusters of colourful roses. This Easy to Grow Roses are Colourful and Long Blooming. These are strong performing plants that work hard with minimal care even in the dead of summer, when landscape duties are the last thing on our mind. Generally such roses are preferred which require very little spraying for plant protection. This need in environmentally sensitive areas has led to the development of low maintenance roses. If any plant has a bad reputation as far as maintenance is concerned - it's the rose. While beautiful in bloom, many often shy away from this plant because of the pruning, insects, and its bare winter form. Many landscape designers are often coming to the defense of the Jekyll and Hyde of the plant world. To be at their best, they should be groomed during the blooming season, often succumb to insect attack, (need chemical control- spray or systemic application) and need to be pruned in a specific manner during the dormant season. Another negative of the hybrid tea roses is their bare winter form. It is preferable to spot this type of rose throughout the landscape, or place a rose garden in a spot where its "Bone Yard Nature" does not command prime attention in the winter garden.

The Butterfly Roses, sporting single flowers that change colour as the flower matures. Chinese Butterfly Rose having creamy yellow, pink and mauve coloured flowers is a large screening plant which grows to approximately 12 feet wide and 8 feet tall. It blooms all season, and is nearly evergreen in the winter - a rare trait for a rose. Other Butterfly roses are Flutter by and Tequila Sunrise. Flutter by has overlapping yellow and peachy - orange flowers and grows to about 7 feet tall by 5 feet wide. Tequila Sunrise is a blend of red, peach, white and orange. All Butterfly roses have single type flowers and are self cleaning. This means that when the flower is spent, they simply fall from the plant, and disappear - no cleanup needed. These roses can grow for years without any pruning whatsoever. However, because of the wide spreading nature of the Mutabilis variety, edging may be necessary to control its wide spreading nature - therefore spot it carefully. They need only a hard pruning once every 5 to 8 years.

Rose varieties having very good foliage preferably pigmented are required as flowering in landscape roses is limited to a season. Generally landscape roses come in a large range of colors, sizes and habits. The roses with compact rounded habit are required to be bred. The varieties which look leggy and naked when not in flowering are not preferred. Varieties which bear in clusters and the flowers or petals dropping giving way to new blooms are required. The varieties which look bad with the retained spent blooms are to be avoided. Varieties viz., Pink Knock Out and Pinata which flower continuously and are disease resistant are suitable as landscape or low maintenance roses. Varieties like Pusa Ajay, Pusa Baramasi and Sadabahar developed at Indian Agricultural Research Institute, New Delhi are suitable as low maintenance roses. One more important factor is the selection of root stock for different climates and landscape situations. The root stocks resistant to salinity and other difficult conditions should be tested and bred so that the spectrum of conditions where roses are grown can be improved.
