Question

How do the ornamental plants propagate? Mention the method of propagation for the following
A) Jasmine
B) Rose
C) Bougainvillea
D) Hibiscus

Answer 1

Hint: All vascular plants can reproduce through vegetative propagation. Some of them do so naturally in nature, while others are induced to do so by artificial means. This can be for floriculture, horticulture, and viticulture.

Complete answer:
Ornamental plants propagate through vegetative propagation. There are many techniques that can be used for this, including cutting, budding, layering, and grafting. Even though these plants may be able to reproduce through sexual reproduction, these techniques are much quicker for the gardener.
Jasmine can be propagated through the process of layering. Layering is when a branch that is touching the ground and grows adventitious roots and is then capable of surviving separate from the parent plant.
Rose plants are generally propagated through cutting. The cuttings can be grown separately in the soil, or grafted onto the stem of another rose bush, which can create plants with more commercially advantageous characteristics.
Bougainvillea is propagated through two techniques. One of which is cutting as the stems can be induced to grow roots when placed in water, as well as through layering of branches which are growing new shoots at the ends.
Hibiscuses are also easily propagated by cutting. The stems are cut just below the node, placed in rooting solution and then planted in soil.

Note: Vegetative propagation of ornamental plants is very beneficial in shortening the time for maturation. Flowering and fruiting are both earlier than plants grown from seeds. This is because stems that are taken from mature plants are already capable of producing flowers, unlike saplings that take a while to mature.
