Answer:

hibiscus

Explanation:

Hibiscus rosa-sinensis (Rose of China). It is attractive due to the usually large, trumpet-shaped and colourful flowers. Besides the ones with red flowers, there are plants with flowers of different colour shades or combination of colours. The large petals form the colourful part of the flower. The plant is grown for its ornamental value. The flower usually lasts a day after fully bloom.

The pinkish-white hibiscus flower seen below is from one of my hibiscus plants. I have labelled it to illustrate the different part of a typical flower. Both male and female organs are found on the same flower.

The five hairy red spots shown below is a close-up view of the tip or stigma (female part) of the flower. The stigma is located at the end of the style branch.

The male part (stamen) of the flower consists of stem-like filaments and each filament ends with the pollen-producing anther. The base of the filament is attached to a cylinder-like stem, known as a staminal column or stamen tube. Below are the stamens from 3 of my hibiscus plants.

Hibiscus rosa-sinensis has a genetic characteristic known as polyploidy, in which there are more than two sets of chromosomes. Due to this genetic characteristic, the offspring may be quite different from the parent. Plant breeders have used this characteristic to produce a wide variety of hibiscus plants with different flower colours and shapes.

The genetic information that produces stamens is closely related with that which produces petals. This closeness in the genes allows development of petals from the stamens. It sounds wired but this is a characteristic of hibiscus flower. The yellow "scramble-egg"-like hibiscus flower below is a result of this phenomenon. For the one with red flower, you can also see some petals forming around the stamen area.

These 9 hibiscus plants were once grown by my father-in-law back in 2009. He was no longer growing them now due to his health condition.
