Why are my sun loving plants not loving my sun?

Why do full sun plants that I buy from a local nursery burn when I plant them in my back yard? For example; I planted a clematis vine in mostly shade and when the sun went down a small amount of sun hit the plant and cooked it. It is very frustrating to see these beautiful plants doing this. This plant was in full sun when I bought it. Please help.

Hi, Well without more information about  your garden I can't be of too much help, but let's first take your clematis situation. This vine likes cool, moist soil with at least 6 hours of sun a day, BUT they don't like sun on their roots. The old saying with clematis is they "like their heads in the sun and feet in the shade". This often isn't an easy thing to pull off so when you plant clematis, put it in the sun, but always mulch the roots heavily if you can't provide shade. Or, plant it behind another perennial or shrub that will protect the roots from the hot sun. BTW, clematis will not grow or bloom in the shade. Now, let's cover a couple other things. Where a plant is placed in a nursery is no real indication of where it will do well. This is especially true if you are shopping in a big box store where plants are moved about at will and not by what they really need. At most independent garden centers you'll have better luck, but still, read the plant label before purchase. Also, soil conditions often make or break plants. Even if they are sun-loving, if you just drop them into hard or clay like soil on a hot day, they will probably die. If you improve your soil, you'll improve you chances of success whether in the shade or sun. Also, be sure to water all plants every day for the first week or two until they have had a chance to acclimate to new conditions. And, if you live in a hot climate ALWAYS mulch with several inches of organic matter to help maintain consistent soil moisture and to protect the root zone from scorching. I'm sorry I can't be of too much more help because I don't have specifics on your particular garden, soil, site or exposure.
