PARTS OF THE GUMAMELA PLANT
Hibiscus rosa-sinensis is a plant that can grow into a bushy shrub or a small tree. It has shiny leaves with egg-shaped bases and jagged edges. It produces flowers in many different colors like red, white, pink, orange, peach, yellow, blue, and purple.
The stem of this plant is strong and hard like wood, but the top part is softer and more flexible. It grows up in the air, standing tall and branching out into different directions.
Its flowers are usually seen one at a time, perfectly balanced and often red. Each flower has five petals that are about 4 inches wide. Inside, you'll find bright orange-tipped red parts called anthers. These flowers have everything they need for making new plants, like a pistil, stigma, style, and ovary. It's like a little factory for creating more beautiful flowers! (Pekamwar et al., 2013).
How to take care of and raise gumamela in your garden?
Here are some key tips to grow your gumamela plant to its fullest:
Enrich the soil with fertilizers having lots of phosphorous in them. This encourages the plant to produce more flowers.
Pruning is a technique used in gardening to help the plant maintain a compact, bushier shape, and promotes growth by allowing new buds to form. So, trim the plant to keep it neat and help it grow well.
Gumamela is sensitive to cold temperatures below 2°C and should be kept in a warm place always.
Watch out for bugs like aphids, thrips, and spider mites and learn to get rid of them quickly.
What do gumamela plants need?
First, gumamela plants must be planted in a soil that drains well with water and does not get easily flooded when a heavy rain comes.
Spray some water on its leaves every now and then, to keep it humid. Water gumamela regularly, but don't overwater it. The goal is to keep the soil wet but not soaked in water as too much water blocks the roots from getting carbon dioxide through air spaces in the soil (Smithsonian Gardens, 2024).
Outdoor gumamela plants need 1-2 inches of water per week. Indoor gumamela plants need water every time the topsoil dries.
When placed outdoors, gumamela requires at least 6 hours of direct sunlight per day, also known as full sun. Indoor plants, on the other hand, require at least 4-5 hours of bright sunlight or part sun. However, light exposure for more than 16 hours a day should be avoided (Taghvael et al., 2022).
What is gumamela known for?
In the Philippines, the red gumamela is a popular plant used in gardens, being dubbed as "The Queen of the Filipino Garden".
In China, the petals have been used to make shoe polish and dye hair black naturally. In India, the flowers earned the plant the nickname "Shoeblack Plant" for their use in shoe shining. In the Pacific Islands, the edible flowers are incorporated into salads and serve as a decorative hair accessory.
The flower can also serve as a pH indicator, turning acidic solutions into dark pink or magenta and basic solutions green.
In traditional Chinese medicine, Gumamela is used to prevent hair loss and dandruff. Gumamela has also been explored for its potential to be used in skin care products, with flower extracts that can absorb harmful ultraviolet radiation from the sun (International Journal of Creative Research Thoughts, 2023).
Gumamela is a polyploid. It has more than two sets of chromosomes, which constitute the genetic material. This allows for the random expression of characteristics from previous generations, enabling the creation of new varieties through cross-breeding (Vankar & Srivastava, 2008).

Gumamela Varieties in PSHS-SMC
Gumamela varieties can be classified based on the shape and color of the flowers they produce.
The red Gumamela is one of the most popular kinds. Its big, bright red flowers are usually 4-10 inches wide and have petals that are in a simple, single . The red color comes from special pigments called anthocyanins. Red Gumamela plants have shiny, dark green leaves and can grow up to 10 feet tall and 6 feet wide. People often use them as special plants in their yards, to make fences, or to line the sides of buildings in warm places (Hammad, 2009)
The pink Gumamela comes in a lot of different shades, from light pink to deep fuchsia. The flowers can be single or double, and some have a red center. Pink Gumamela plants are usually smaller than red and white ones, growing 4-6 feet tall and 3-4 feet wide. They look great planted together with other flowers, as special accent plants, or in pots on decks. Some popular pink kinds are 'Brilliant', 'Seminole Pink', and 'Bali' (Slamet, 2018).
The white Gumamela, sometimes dubbed as "White Wings" or "Snow Queen", have pure white flowers that really stand out against the green leaves. The flowers can be single, with just one row of petals, or double, with extra petals that look like they came from the male parts of the flower. White Gumamela plants usually grow 4-8 feet tall and 3-5 feet wide. People love how elegant they look and use them in tropical gardens, as cut flowers in bouquets, or in pots on patios (Slamet, 2018).
Breeding Techniques for Gumamela
It involves breeding two different varieties of gumamela to produce hybrids with a combination of desirable traits from each parent plant such as unique flower colors, forms, and sizes (Akpan, 2007; Hammad et al., 2009).
Choosing parent plants with specific desirable characteristics, such as large bloom size, bright colors, attractive patterns, cold tolerance, etc. helps produce the ideal plant for flower shops, gardens, and homes (Kuligowska et al., 2012; Mercuri et al., 2009).
Removing the male reproductive parts (anthers) from the female parent flower before pollination to prevent self-pollination and ensure cross-pollination with the desired male parent controls the parentage of traits present in the gumamela plants (Janakiram & Patil, 2017).
It involves the transfer of pollen from the anther of the male parent to the stigma of the female parent. This is to facilitate cross-fertilization and produce varying traits, which result in a more colorful set of flowers. The pollen carries the male genetic material. (Kuligowska et al., 2012).
A stem cutting from one plant is joined to the root system of the another to combine desirable traits. The scion (stem piece) then grows into the desired variety of gumamela (Janakiram & Patil, 2017).
Gumamela can be treated with radiation or chemicals to cause genetic mutations in the plant, which can result in new desirable traits such as unusual flower colors or shapes. This creates more genetic variety and highly attracts customer attention (Akpan, 2007).
Breeding between two gumamela plants of the same species combine desirable traits while preserving the integrity, overall plant quality, bloom size, color, etc. Hybrids from the same species allow for more compatible crosses (Akpan, 2007).
Breeding a hybrid with one of its parents or a genetically similar plant to introduce specific desirable traits from that parent into the hybrid helps stabilize and enhance certain characteristics (Mercuri et al., 2009).
