Perennials are those plants that come back year after year. If you have most of your landscape in perennials, you will only have to fill in with some bright summer annuals each year. The list of summer perennial flowers is long, but there are a few popular types that you see and hear of often.
Nothing says wholesome girl next door like the Shasta daisy. It is a simple flower that's loved by many. The long green stems are covered in thin, jagged-edged leaves, which give way to large white peddles and yellow centers. An added bonus to this perennial is that it is easily grown. You can even start the seeds indoors early and plant the seedlings outdoors after the last frost has passed. Start with a nutrient-rich and well-drained garden soil and mix in some compost before planting. Make sure your daisies get plenty of water and sunshine. If you deadhead (remove dead flower blooms) through the season, the Shasta daisy will bloom even longer.
A flowering hydrangea bush can mature to a size of 4 feet wide and 4 feet high, some varieties even taller. The enormous blooms are made up of smaller blooms. You'll see them in pink, blue, purple, white and sometimes with a tinge of red. The color of this flower has more to do with its soil than the variety. Although a white hydrangea won't turn blue, a pink one will. It just needs the proper soil combinations: aluminum sulfate, high potassium and an acidic soil of 5.5 or lower. Although there are 23 species, there are only five that are widely grown in the United States. The most popular is Hydrangea macrophylla, commonly known as Big Leaf (French or Florist's) hydrangea.
Roses are considered the most romantic flower. This summer perennial has an uncountable number of hybrid varieties. Breeders work on creating new ones every day. There are nine basic types of roses. Hybrid tea roses are the long-stemmed beauties found in florist shops. You can pretty much find any color of this type of rose, except black or blue. Florabunda roses are known by their clustered blooms on a smaller plant. This type of rose is used more in landscaping. Grandifloras are a mixture of hybrid tea and florabunda. Miniature roses have small everything: blooms, leaves and bush size. Mini-floras are larger than a miniature rose but are too small to be any of the other types. Climbing roses are just that, a plant that climbs like a vine. It is seen most often growing up trellises or over arbors. Old garden roses include any variety that was in existence before 1867. Shrub roses seem to be any variety that doesn't fit into another category. Polyantha roses have small bushes and small blooms but are not as small as miniatures or mini-floras.
When deciding where to plant your rose bush, choose a sunny location. It should have at least six hours of sun per day. Morning sun is best. Roses are known to have problems with mildew. To avoid this, do not water in the evening so that the plants have a chance to dry.
