    I am doing a landscaping job and before i settle on a design i want to make sure the plants i am using will be okay in full sun in river rock around a pool. They are:
    Limelight Hydrangea
    Quick Fire Hyrandgea
    Gold Thread Cypress
    Various grasses (not worried about these)
    Daylillys (these either)

    Depends on you local climate. Full sun where I live, 102 today
    And full sun in colorado are completely different and will affect those plants much differently.

    I am in NJ we usually dont see more than 100 but 3 or 4 times a summer. This summer so far has been cooler than past years. Its mid 80's with only 3 days in the 90's so far and they were in April. Summer is usually low to mid 90's

    I personally would never plant hydrangeas in full sun where I am from. They just fry. I would really investigate whether or not those specific varieties can handle full sun, in your climate.

    In my experience river rock tends to absorb heat and tends to be much hotter than walk on bark or humus. I would also take that into consideration.

    My advice would be to call your local nursery, and describe to them you situation. They should be able to give you some concrete advise.

    The hydrangeas will probably just fry like the previous poster said. If you want a flowering plant for full sun, try Clematis, Delphinium, Sea Thrift, or Sea Holly.

    These are all full sun and very colorful.

    The arbs and cyprus will be okay for sure.

    I would be more worried about the heat storage of the stone. Reflected heat from buildings or other infrastructure kill more landscaping than you would think. Regardless of where you are located, Hydrangeas don't like reflected heat.

    Try large Potentillas. They won't be cheap, but the impact will be worth it and they tolerate full sun in most areas.

    I talked to the nurrsery today and they insisted that both the quick fire and limelight hydrangea would be fine. He said any other variety would fry but these 2 are full sun and will make out well there.

    nurserys also dont know how to plant trees and shrubs, nor do half them have a degree in this industry. Most hydrangeas are part sun required.
