Assignment 2 Outline: Mugunghwa (Hibiscus syriacus)

Introduction

Common and scientific names

1. Common names: “Mugunghwa,” the rose of Sharon,

2. Scientific Name: Hibiscus syriacus (Anjum, 2016).

Where it is observed

· The flower’s native region East Asia, China to India.

· It is regarded as the national flower of South Korea.

· This flower is mostly found wild in the mountains slopes

Why I chose this organism?

· I choose Hibiscus plant since its represents the beauty of the natives, plays the decoration role at home, and gardens.

· Its medicinal aspects and uses in cancer therapies, infections, fever, stomach upset, high blood pressure, and weight loss.

· I am currently stationed in South Korea.

· It represents the beauty aspects of the environment.

Body

Physical Description

· It is hardy and deciduous

· Bloom color: Purple, White, Pink, Blue, and Lavender.

· Size: It grows to 3 m (9ft) by 2 m (6ft) at a medium rate ("Hibiscus syriacus rose of Sharon, althaea, shrub Althea, hardy hibiscus PFAF plant database," n.d.) .

· At a high rate, it grows up to 8-12 ft. tall and 6-10 spread.

· In satisfactory growing condition, the plant can self-seed aggressively

· Flowers are short-lived and grows numerous buds.

· Has 5-petaled flowers

· Most of the contemporary cultivars are virtually fruitless.

· The leaves are yellow-green, alternate, and ovate.

· The branches are grey

Life Cycle and Reproduction

Life Cycle

· It grows up to 24 inches annually until it meets its natural or 8 to 12 feet.

· It is perennial in the United States

· Optimal growing conditions help the plant grow faster to reach its maximum height by four to six years.

· It has a self-supporting or sufficient growth form

· It blooms during the summer to producer flowers

· Unlike other shrubs rose of Sharon blooms within 1 to 2 years (Christensen, 2019).

· Frequent pruning is advisable to keep it young, since it can grow up to 24 ft.

· It attains it maturity when the flowers begin to form.

· After flowering it seed capsules that split in the landscape to form the next generation (Blackstone, 2020).

Reproduction

· In later summer and fall, the flowers bloom in masses.

· The reproduction occur through pollination by insects of birds like hummingbirds (Brown, 2019).

· They eventually become the seed pods, but they may be sterile and produce no seed for propagation.

· The flowers develop into seed pods in October and they take six to fourteen weeks to mature and ripen (Larum, 2016).

· The seeds grow with five lobes, and each lobe contains at least three to five seeds.

· Once the seeds mature, they turn brown and dry up to split each lobe and seeds disperse (Larum, 2016).

· The seeds need a cold environment to germinate.

The Stem Anatomy and Physiology

Anatomy

· It has the epidermis made up of the polygonal axially elongated cells with straighten anticlinal walls.

· Devoid of stomata.

· The epidermal cells are divided transversally.

· The hypodermis is elongated.

· The cork is formed in a minimum of three rows organized dark brown tabular polygonal with tangentially elongated cells encompassed with thick walls (El Shazly, El Gayed, Kandil, Yassin, Tawab, & ElAlfy, 2018).

· The phelloderm is made of at least three rows of elongated and tangential in shape with thin walls parenchyma cells (El Shazly, El Gayed, Kandil, Yassin, Tawab, & ElAlfy, 2018).

· The phloem is made of sieve tubes, conducting cells, and fiber cap.

Physiology

· The stem functions to provide support to the flowers, and buds.

· It conducts waters and nutrients to the flower and seeds ( Smith, 2019).

Energy Ecology

· Hibiscus Syriacus thrive in full sun and its growth goes dormant during winter except for the hardy Hibiscus.

· Less than full sunlight results to fewer flowers.

· It is a primary producer through photosynthesis.

· It assumes high mechanisms of adaptation in the structural and traits of the photosynthetic apparatus (PA).

· Its Chloroplast photosynthetic pigments makes the basics for photosynthesis.

· Their composition and the quantitative correlation establishes rate of photosynthesis and resistance level to unfavorable conditions (Akinshina, Azizov, Shtonda, Khalmurzayeva, & Rakhmatullina, 2018).

· It stores energy during unfavorable conditions by shedding buds.

Habitat

Abiotic factors

· It thrives best in zones 9-10, in acidic, moist, and well-drained soil.

· Prefers direct sunlight and moderate temperature for efficient thriving.

· It grows well during summer and dormant during winter.

Biotic Factors

· They are prone to leaf spots, rusts and cankers.

· Highly affected and invaded by aphids, whiteflies, and Japanese beetles.

· These insects can severely damage the foliage.

Conclusion

· The flower’s native region East Asia, China to India.

· I chose it due to its medicinal aspects and uses in cancer therapies, infections, fever, stomach upset, high blood pressure, and weight loss.

· Flower are short-lived, and grows numerous buds.

· It grows up to 24 inches annually until it meets its natural or 8 to 12 feet, which can go up to six years.

· Its reproduction occurs through pollination by birds and insects.

· It taps enough through photosynthesis and stores by shedding off the buds during unfavorable conditions.
