As is well known, among the flowers in nature, blue-hued flower materials are very rare. Today, let's share a kind of flower with unique blue blossoms, "Evolvulus nuttallianus", which is also called "Ruellia simplex" by some florists.

Generally speaking, Evolvulus nuttallianus can be easily found in the flower market from late spring to early autumn. It is a herbaceous plant native to South America. The ornamental period of fresh cut flowers can reach about 15 days. The flowers are very small and lovely after blooming. The petals are layered and look like a blue starry sky, and are mostly used as accessory flowers.

So, how to maintain fresh cut flower materials in daily life? First of all, the leaves and roots of Evolvulus nuttallianus will have white sap flowing out, so be sure to wear gloves when pruning to avoid allergic reactions of the skin caused by the sap. Then, after cutting, the roots can be rinsed in a cup of warm water for about 20 seconds before being placed in deep water for flower refreshing. The flower refreshing time can be about 2 to 3 hours. After the flowers are refreshed, we still need to wear gloves to start arranging the leaves. It's fine to keep only a few ornamental leaves, and the rest should be removed. Finally, choose a favorite vase, add 1/2 of water, hold the flowers in your hand, and cut the roots diagonally according to the height of the vase. Please note that every time the roots are cut diagonally, sap will flow out. This white sap is insoluble in cold water. So after cutting, it should be quickly rinsed with warm water for about 20 seconds and then taken out. After rinsing, wipe the liquid clean with a tissue and then put it into the vase. Change the water once a day in summer and clean the vase each time to maintain ventilation.

For flower enthusiasts who like to grow potted plants, the maintenance points of Evolvulus nuttallianus are very simple. It is relatively drought-tolerant and likes well-drained soil. Therefore, there is no need to water too much in daily life. It is suitable to follow the principle of "exposed to light and moist when necessary". The placement can be chosen on the balcony or by the window because it is not afraid of sunlight. However, in case of hot days with temperatures above 35 degrees Celsius, attention should be paid to avoiding direct sunlight. Finally, to grow it well, fertilization is indispensable. During its vigorous growth season, an appropriate amount of compound fertilizer can be applied to ensure the supply of nutrients.

Overall, as long as given appropriate light, water and fertilizer, Evolvulus nuttallianus can thrive at home and add a bright color to the home.
