Orange is a great color to add to almost any area and will surely brighten up any space. Whether in containers by themselves or in a hanging basket for your patio, orange flowers are a wonderful option to add some summer cheer to your garden.
There are plenty of orange perennials available in the market today, but planting with annual flowers gives a few more options to work with. These annual plants are oftentimes a little tougher in the summer heat due to their shorter life span.
If you are interested in adding some cut flowers to your garden, snapdragons or Gerbera daisies might be the right plant for you. Adding some color to a shady area of your yard or garden?
