Vertical garden is one of the approach of green building envelope with green facades and green living walls creates a richer ecosystem, enhances biodiversity, improves mental health, alleviates environmental externalization generated by urban areas (Pollution, runoff and heat island effect etc).  However, the limitations of vertical gardening system are the choice of plants and the module of growing. Numerous exotic and native ornamentals are suggested for vertical systems based on the requirements. Selection of plants grown under indoor environments with limited space is narrowing down the choice of ornamental flora. On the other hand hydroponics is an alternative sustainable production system under conditions in which resources are limited. Hydroponics is a very young science which has commercial basis during recent days. However, even in relative short period of time it has been adapted in many situations from outdoor to indoor for growing various crops. Hence, an experiment was conducted with Hoagland & Arnon solution (1938), Cooper’s solution (1979), Saparamadu’s solution (2010) and Mattson and Peters solution (2014) and a control with Irrigation water to study the rooting behavior of five plants viz., Devil’s ivy (Epipremunm aureum), Wandering jew (Zebrina pendula), Arrowhead plant (Syngonium podophyllum), Philodendron (Philodendron erubescens), Boat lily (Tradescantia spathacea) under passive hydroponic vertical garden module. The pH was monitored for acidity and basicity range and EC were monitored for salt concentration in all the nutrient solution periodically. Observation on root parameters viz., Number of roots plant -1, Root length (cm) and Root weight (g plant-1) were observed at 30, 60 and 90 days after planting. Results of the experiment revealed that number of roots, root length and root weight exerted maximum values in those plants grown under T3 (Cooper’s solution). Minimum rooting with lowest weight was recorded in T4 (Saparamadu solution) in all the stages of observation in devil’s ivy. Whereas in other four ornamentals viz., Wandering jew (Zebrina pendula), Arrowhead plant (Syngonium podophyllum), Philodendron (Philodendron erubescens) and Boat lily (Tradescantia spathacea) recorded lowest root parameters in T1 (Irrigation water) under 30 days of observation and at 60 and 90 days minimum number of roots, root length and root weight was recorded under T4 (Saparamadu solution).
