Petunias are not exactly at their peak allure right after a heavy rainstorm or on generally wetter and colder environmental conditions.
The good news is that the "wave" series of hybrid petunias such as the tidal wave or the easy wave petunias are less bothered by these conditions and therefore, less maintenance is required.
In addition, these flowers will look better overall in climactic conditions not best suited for petunias in general.
Creating a mound, wide, blanket-like spread of wave petunias, or planting climbing petunias on small fences or trellises will be more attractive right after they've gotten soaked.
Whereas other petunias will be more ill-looking in an environment of commonly recurring and / or sudden rain storms, these types will not.
In cooler, wetter climates petunias are harder to grow.
Nonetheless, you can increase your flowers' chances of survival by taking certain precautions.
There are certain environmental conditions that are, of course, better for your petunias than others.
Of course, you must consider your environment and any special needs that your petunias (or any other plants in your garden) will have to be cared for to compensate for lack of humidity, shade, and many other variables.
You do not want your colorful petunias to hang her heads after a thunderstorm or to have their petals torn apart by wind and hard rain.
The wave varieties of the petunia plant, created by a scientist named Dr.
Walraven, are likely to spread more effectively, be more pleasing to the eye.
And, most importantly, to bounce back from any damage caused by a wet or cold wave of weather.
