Question:

Which of the following climber is categorized as light climber?

Show Hint

To identify light climbers in floriculture, look for species with slender, herbaceous stems and tendrils, such as Antigonon leptopus (Coral Vine) or Clitoria ternatea (Butterfly Pea).
  • Quisqualis indica
  • Petrea volubilis
  • Antigonon leptopus
  • Wisteria sinensis

The Correct Option is C

Solution and Explanation

Step 1: Understanding the Concept:
In landscape design and ornamental floriculture, climbers (vines) are grouped into categories based on their growth vigor, stem woodiness, weight, and the support structures they require.
These categories include heavy climbers, medium climbers, and light climbers.
Heavy climbers produce woody stems (lianas) and require strong, permanent support structures like brick walls, pergolas, or concrete pillars.
Light climbers have thin, flexible, herbaceous, or semi-woody stems.
They grow rapidly but remain lightweight, making them suitable for growing on wire mesh, light wooden trellises, or small arches.

Step 2: Detailed Explanation:

Let us analyze each of the given climbers:
(A). Quisqualis indica:
Commonly known as the Rangoon creeper, this is a vigorous, woody perennial climber.
It develops heavy, woody stems and extensive foliage over time, requiring a sturdy trellis or wall for support.
Thus, it is categorized as a heavy climber.
(B). Petrea volubilis:
Commonly known as the purple wreath or queen's wreath, this is a robust woody climber or scrambling shrub.
It produces woody stems and a heavy canopy of star-like blue flowers, requiring strong, permanent support.
Thus, it is categorized as a heavy-to-medium climber.
(C). Antigonon leptopus:
Commonly known as the coral vine or sandwich Island creeper, this is a fast-growing climber with thin, slender, tendril-bearing herbaceous stems.
It produces delicate, light-green leaves and clusters of pink or white flowers.
Because its stems remain thin and lightweight, it does not put significant structural load on its support.
Thus, it is classified as a light climber.
(D). Wisteria sinensis:
Commonly known as Chinese wisteria, this is an extremely vigorous, long-lived woody vine.
Its stems can grow into thick, trunk-like structures that are capable of damaging weak support structures.
Thus, it is categorized as an exceptionally heavy climber.

Step 3: Final Answer:

Therefore, the climber categorized as a light climber is Antigonon leptopus.
