will they live or wont they.........

Ive ventured into the dark side.... well for me it is..... everything i EVER plant dies, but im hoping that these might be different.lol I can dream eh!! I got 2 nice pots to put at the back door and filling them with yummy herbs, tis right near my kitchen, so will be very handy. Also put a nice pot near the front door with some pretty bright coloured tulips and the pink flower cant remember what it is. also got a couple nice camelia trees to plant at the side of the carport, to bring some colour to the front yard/brickwall. hopefully it all pays off and they GROW and not die on me!!!! fingers crossed!!!!! Also want to go back and get a few other bits and pieces including a lemon and lime tree to put out the back, ive always loved those trees! trying to decide wether to get normal size trees to plant in the yard or get dwarf trees and put in big pots along the verandah...... anyone got lemon or lime trees or an opinion on them!!
