Hi Oz,
Nice to see you back.
How about African Violets? Pretty when they flower and, as long as you only water when dry, will go on for ever! You could try Jasmine officianalis, lovely scent, same with Plumbago, but both climbers so need some wire in the pot!
Herbs in pots, especially basil for all those summer salads!
By the way, get a spider plant to put close to your puter - they absorb some of the bad electricity of all our gadgets - was told by Seeboard sub station designer who loved gardening!
Happy Potting ;D ;D ;D
