    Hi i might have signed in with the wrong ideas, All I want is to know what plants do best on and roof top garden. I have just been lucky enough to rent a penthouse which faces south/west and west/north.
    It is a tar and gravel roof with a deck and a 50 foot long west/north wall. I would like to have some big pots and hanging baskets. not sure what will grow.
    If you can help it would be greatly apprieciated.

    Growing plants on a rooftop in a city takes some knowledge. It would be best to consult with a specialist in this area. Considerations include the structure of the outdoor area and it's ability to hold the weight of pots, soil and water. Wet soil can be VERY heavy, especially when plants and pots are added. It is often best to fill the bottom of the containers with lightweight material such as styrofoam. Fiberglass pots are lighter then ceramic or clay. Clay pots left outdoors in northern zones can crack from freeze and thaw conditions. Other considerations for which plants to use will be your hardiness zone, the sun and wind conditions (wind dries out plants) and access to water. Drip irrigation systems are often a must. You may even need permission from your landlord as there might be weight restrictions.

    I would suggest you start by asking friends and/or relatives and/or neighbors who have done this who they would recommend to make the appropriate site assesment and recommendations.

    Best of luck,
    Newt
