Nasturtium is a beautiful flower widely planted in many countries. In daily life, nasturtium is often used as ornamental flowers and medicinal materials. However, many people do not know about the life cycle and characteristics of nasturtium, nor do they know whether it is a perennial plant. In this article, we will conduct an in-depth investigation of nasturtium to answer this question.
I: Understanding Nasturtium
Nasturtium (scientific name: Portulaca oleracea), belonging to the family Portulacaceae, is a succulent herbaceous plant. It usually grows in sandy soil and prefers warm and sunny environments. Due to its strong drought tolerance and salt resistance, it is known as "drought-tolerant vegetable".
II: Morphological Characteristics of Nasturtium
The stem of nasturtium is semi-prostrate or ascending, generally 10-30 cm in height. Its leaves are fleshy, glossy, oblong or ovate, green or red. Its flowers are yellow, white or red, with a diameter generally between 1-2 cm.
III: Life Cycle of Nasturtium
Nasturtium is an annual or biennial plant, and its life cycle includes germination, growth, flowering, fruiting, and death. From seed to death, it generally takes 8-12 months.
IV: Growth Process of Nasturtium
The seeds of nasturtium require a temperature of 15-35°C for germination. After germination, its seedlings begin to grow, and the stems and leaves gradually lengthen. During the flowering period, nasturtium opens its beautiful flowers to attract insects such as bees to collect nectar.
V: Reproduction Methods of Nasturtium
Nasturtium can be propagated by seeds and division. Seeds need to germinate under appropriate temperatures, while division needs to be carried out in appropriate seasons.
VI: The Perennial Issue of Nasturtium
Nasturtium is an annual or biennial plant, not a perennial plant. This is because its roots and stems do not have sufficient survival ability and can only grow and reproduce for a short time.
VII: Distinguishing Nasturtium from Perennial Plants
Compared with perennial plants, the life cycle of nasturtium is shorter. Perennial plants can grow in the same place for many years, while nasturtium can complete its entire life process within one growing season.
VIII: Nutritional Value of Nasturtium
Nasturtium contains large amounts of vitamin C, vitamin A, zinc, iron and other nutrients needed by the human body, and has certain effects on enhancing immunity and improving anemia.
IX: Medicinal Value of Nasturtium
Nasturtium is widely used in traditional Chinese medicine. It is believed to clear heat and detoxify, moisten the lungs and relieve cough, lower blood pressure, etc., and has good medicinal value.
X: Common Uses of Nasturtium
Due to its beautiful appearance and rich nutritional value, nasturtium is widely used in food, health products, beauty products and other fields. At the same time, nasturtium can also be used as a greening plant and ornamental flower.
XI: Distribution Areas of Nasturtium
Nasturtium originated in South America and has now been introduced to all over the world. In China, nasturtium is widely distributed, especially common in southern regions.
XII: Planting Methods of Nasturtium
The planting method of nasturtium is relatively simple. You just need to choose suitable soil and environment, and sow and manage according to a certain way. Specific planting methods can refer to relevant professional materials.
XIII: Application Prospects of Nasturtium
As people's demand for health and beauty continues to increase, nasturtium, as a nutrient-rich and highly medicinal plant, will have increasingly broad application prospects in the future.
XIV: Conservation Significance of Nasturtium
Due to severe damage to the growing environment of nasturtium, its quantity is gradually decreasing. Protecting the ecological environment of nasturtium and preventing its picking and destruction has important conservation significance.
XV:
In conclusion, nasturtium is not a perennial plant, and its life cycle is generally one or two years. As a herbaceous plant, nasturtium has many important application values. We should strengthen research and protection of it to promote human health and beauty.
