Floristic diversity of native wild ornamental plants of Aravalli Hill Range: a case study from district Rewari, Haryana, India

Abstract

Ornamental plants are important constituent of floristic diversity which beautify and glorify our surroundings. They add a positive attitude to life, intensify the feeling of happiness, and enhance the economic value of the estate. There has been a growing trend promoted by environmentalists, ecologists, and horticulturalists toward the inclusion of new wild ornamental plants (WOPs) for minimising their maintenance costs and enhancing their survival rate. The current study inventorised the floristic diversity of native WOPs of the Aravalli Hill Range of Haryana State. Researchers recorded 88 native WOPs species belonging to 40 plant families. Asteraceae and Poaceae are the most dominant families, contributing seven species each followed by Fabaceae and Malvaceae with six species each. The habit wise distribution of native WOPs from the Aravalli hill ranges depicted that herbaceous types of plants are dominant with 53.4 % followed by trees (18.2 %), climbers (14.8 %), and shrubs (11.4%). These native WOPs were found suitable for various ornamental purposes which ranges from the garden, potted, medicinal, lawn cover, avenue tree, hedge/fencing, edible, religious/ ceremonial, road dividers, cacti, succulent, and indoor foliage. The current study documented four plants, viz., Argyreia cuneata (Willd.) Ker Gawl., Boswellia serrata Roxb. ex Colebr., Pulicaria wightiana (DC.) C.B.Clarke, and Rivea hypocrateriformis (Desr.) Choisy. endemic to the Indian subcontinent. Blumea lacera (Burm.f.) DC., Cleome viscosa L., Saccharum spontaneum L., and Triumfetta rhomboidea Jacq. were reported to have somewhat invasive potential in this region. Further, it is also suggested to introduce some potential native WOPs into domestication by florists, horticulturists, nurserymen, and municipal authorities for the protection, conservation, and perpetuation of these plants to minimize the use of foreign floral species to control the further spread of alien plants.
