Thanks, Cinta and Elfie. Both of your suggestions are taken for well consideration and deep study. Elfie's advice on preparing for pot use are surprisingly helpful for me, a beginner. Cinta's links help me for quick browsing at the suggested plants. You are all very helpful. Thank you. (I'll respond when done enough homework)
Since I am just starting to grow plants (houseplants), don't know much about plants especially those plants names are like a new language to me. If anyone could show pic related to the plants suggested, it would make me lot easier to catch idea and to be inspired. Appreciate all your help and advice.
