Roses usually require a lot maintenance, including sometimes meticulous pruning and training, to keep them thriving, but well manicured. If you're looking for plants that grow flowers which resemble rose flowers, but are perhaps easier to grow and maintain, there are several plants you should consider.
Just when many flowers are dropping their blooms and dying back, camellias are getting ready to bloom. Many camellia varieties, such as Dahlohnega, Lady Fernada and Jerry Hill, bloom beautiful roselike flowers in the fall, winter and early spring, adorning gardens in a sometimes otherwise drab time of year. Most camellias are hardy in USDA plant hardiness zones 6 to 8.
Rosebud azaleas are shrubs that have flowers which resemble roses when the buds are first opening up. They appear, as their name implies, like rosebuds. Rosebud azaleas have approximately 1 3/4-inch flowers that bloom in late spring and early summer. They are hardy in USDA plant hardiness zones 5 to 8.
Double impatiens are annuals that grow double blooms that look like roses. Flowers bloom in an array of colours, such as purple, pink and white, from midsummer to fall. Plant double impatiens after the last frost in all climates. They will begin to die after the first freeze.
There are some other flowers that look like roses. For example, moss rose is a trailing annual with flowers that looks like roses. Ranunculus are flowering bulbs that grow flowers that have layers of petals that resemble roses. Double flowering quince don't just have blooms that resemble roses, but they also have thorns.
