Yes,Haian..they are ideal for tubs or hanging baskets..being a trailing variety..They tolerate rain ,wind and sun of course..better than ordinary Petunias..no need to dead head either,they are self dead headers...they spread out well,so you don't need many to a pot,or basket...you could also have something upright in the centre,and have these round the edges? good luck,and welcome to Goy...

Thanks very much Bloomer, I am new to gardening and your answer is very helpful

you are welcome,Haian..everyone is very helpful on here,so ask away anytime :o)

Agree with Bloomer's answer, except to say that surfinia petunias get quite long (mine get over a foot, sometimes 2 feet long) so unless your tub is quite a tall one, they may well be trailing on the ground by end of summer. Very good in hanging baskets though...
