Some only grow to six feet tall, bearing clusters of small, primrose flowers in pink, purple, blue, purple, or white. Most are perennial plants, dying to the ground in winter and returning in spring. While these tall, relatively thick plants provide fall color in fields, they are also often considered “encouragements” for the average garden. However, there have been increased varieties of perennial stars that are suitable for home flower garden.
They are good partners with chrysanthemums because they are taller for background use, and can add a range of color to a fall flower border. Hardy asters received much favor in England where most of the work was done to develop better varieties. In England they are often called Michaelmas daisies, because they reach their peak bloom around St. Michael’s Day, Sept. 29.
Most varieties available today are hybrids including New England asters, New York asters, and some other species. Despite the color of the casual wear, hard stars have not received widespread use in the United It was one reason for this high growth rate. However, the new varieties are much bushier and only two to three feet tall. They are useful in the middle of the flower border of near-perennials, such as oriental poppies, dying in mid-summer. They can spend this empty space as they expand.
Another reason they did not grow is because they are susceptible to several leaf diseases. The most common leaf diseases are rust and rust. While this does not seriously damage the plants, the leaves can look misshapen. Their use is therefore to be used in background plants in a place where the base is often hidden from other plants. Some are low, bushy, and make mounds, which mostly bloom with leaves.
Another problem is the aster disease, which causes deformation of the flowers and the growth of the branches. When the disease is established, the plants must be destroyed. Generally, however, hard asters perform well in the average garden, and are more suitable where durable, low maintenance types and can tolerate poor soil , although the growth will be less dense.
It likes plenty of moisture, but it will not tolerate humid areas. Since these plants are prone to foliar diseases, they are not dense, but satiated, where good air movement around the leaves occurs. a>. To contain shorter and more heavily branched plants, it is useful for any shoots in healthy
