During summer, you can find many types of blue flower blooming in your garden. Some of the common blue flowers include: Hyacinthus, Irises, Dendrobium, Blue skyflower, and Russian sage. These flowers are very colorful and make your garden look brighter.
Dendrobium
Various species of Dendrobium are native to New Zealand, Australia, and South East Asia. Most are grown in Asia, but the dendro (pronounced “dor”) is also cultivated in Hawaii and Costa Rica. The plant is a good choice for an indoor plant as long as it gets a good dose of light, water, and air circulation. It also does well in the garden. The best temperature for the plant is 18-22 degC.
The plant has three or four canes and eight to twelve leaves. It will require some attention after flowering. It requires about a quart of water per week and orchid food every month. It is also best kept at a temperature of 15 to 17 degrees celsius for best vase life.
Hyacinthus
‘Pink Pearl’ hyacinths are perfect flowers to create an eye-catching centerpiece. These hyacinths are perfect for growing in containers or in your garden. They will thrive in moderately fertile soil, and bloom when the temperature drops to 60 deg F.
Hyacinths are a popular spring flower that grows well in full sun or light shade. They are deer resistant, and have a wonderful scent. Hyacinths are also perfect for formal arrangements. They are also fragrant, and make long-lasting cut flowers.
Hyacinths are very popular for planting in containers. They can be planted in containers with drainage holes, or placed in a hyacinth bulb vase. These containers can be filled with coconut coir, or a combination of compost and bone meal. The bulb vase should be filled with water just below the bulb, and placed in a dark, cool place.
Hydrangea
Using chemicals to change the color of hydrangea flowers is not new. In fact, the role of aluminum in hydrangea colors was known as early as the 1940s. However, the chemical manipulation of hydrangea colors was not widely practiced until about two decades ago.
The hydrangea flower has been known to change color from pink to blue. The process is known as hydroxidation and involves the use of aluminum ions.
In general, blue hydrangeas prefer moist soil. In addition, hydrangeas prefer light shade during the hottest part of the day. However, there are hydrangeas that are grown in alkaline soil that produce blue flowers.
One way to get the color of a blue hydrangea is to mix a gallon of water with 1/4 oz of aluminum sulfate. This solution can be purchased at most garden centers. The hydrangea is encouraged to grow by the solution.
Irises
Generally speaking, Iris is a plant that grows in wet areas, such as marshes. Some of the types of iris have fine foliage, while others have sword-shaped leaves. There are also a variety of irises that grow in shade.
Irises are known for their flowers, which are usually blue or purple. These flowers are commonly used in bouquets. They are also commonly used in traditional gardens honoring the Virgin Mary. Irises are also recognized for their medicinal uses. The genus Iris is very large, with over 200 species and more than a thousand cultivars.
Irises are easy to grow. They can be planted in the spring or early summer, but they will take some time to establish. The best time to plant iris is late summer to early fall. In some regions, such as Southern California, you may plant in late July through October.
Russian sage
Whether you want to plant a small garden bed or a low growing hedge, Russian sage is an effective choice. This semi-woody flowering perennial is hardy, deer resistant, and attractive in both dry and moist landscapes.
Russian sage is ideal for low growing hedges, and looks good planted with tall ornamental grasses and bold foliaged plants. Its long-lasting, airy blue flowers make it an effective plant for summer.
When planting Russian sage, it is important to select a site that receives full sun. It does not perform well in partial shade. It also requires good drainage. It is not recommended for use in lawns or other wet areas, as it is susceptible to root rot.
Blue skyflower
Often called the Blue Skyflower, this plant is also referred to as the blue thunbergia. It is a tropical Thunbergia plant native to the Indian subcontinent, Madagascar, Thailand, and Southeast Asia. The plant is a reliable flowering vine that grows well in full sun or part shade. In warmer, frost free tropical climates, it can remain evergreen.
Aside from the blue flower, there is also a white flowering variant. The most common color is sky-blue. The skyflower is a herbaceous perennial wildflower originating from the terminal corymbs of axillary corymbs. The corolla of the skyflower has five petals, each of which is separated by five filaments.
