Hydrangeas are popular plants here in the south, but it might be tough to grow one in your garden if you don't have a semi-shaded environment to offer. The good news is there is one variety of hydrangea that thrives in the sunshine. Hydrangea paniculata, or panicle hydrangea, can grow in full sunshine; at least half a day of sunshine will give enough flowers for a good show. Most have a white flower, but some varieties will start with a green flower that ends up white, and some may go through a pink stage before they turn brown. They will bloom on new growth, so feel free to cut them back in the spring if needed.
There are several varieties of hydrangea paniculata for you to choose from. One is called bobo, and it's perfect for a small garden as it doesn't get very tall. The silver dollar variety also doesn't get very tall, and can take the heat of southern summers. One popular variety is called limelight; it has a lime green flower and can grow 8 to 10 feet tall. With several varieties to choose from, you can find the perfect one for that sunny spot in your garden.
