Like me 
I have a awful garden, so dull. I always seem to kill plants and flowers, despite watering. I planted loads of pansies in the spring and they've died, garden is full o empty pots needing to be filled.
So my question is, are there anything I could plant that would last most of the year? I don't want to buy and pot now if they'll only last until September?
I really want a pretty looking garden so would appreciate any help
TIA
