🌸 Use of trees, shrubs
Learn how trees, shrubs, climbers, palms, and indoor plants are used in ornamental garden planning and landscaping.
Trees, shrubs, climbers, palms, and indoor plants form the structural and visual backbone of landscape gardening by combining shade, privacy, seasonal color, and spatial design.
Role of Trees in Gardens
Trees are used as specimen plants, avenue components, windbreaks, screens, and shade providers.
Two broad groups are commonly used:
- Shade/foliage trees.
- Flowering ornamental trees.
Commonly used examples include Azadirachta indica, Albizia lebbeck, Ficus spp., Grevillea robusta, Delonix regia (Gulmohar), Cassia fistula, Jacaranda mimosifolia, and Plumeria spp.
Avenue and landscape value
- Provide summer shade and thermal comfort.
- Improve road and campus aesthetics.
- Act as long-term framework plants.
Arboretum concept
An arboretum is a planned area where different tree species are grown and maintained for display, learning, and conservation.
Shrubs and Shrubbery Borders
Shrubs are woody or semi-woody perennial plants that branch from near the base and usually remain shorter than trees.
Landscape uses:
- Foundation planting around buildings.
- Borders and partitions for privacy.
- Flowering display at eye level.
- Hedges, topiary, and potted ornamentals.
Common shrub examples: Hibiscus rosa-sinensis, Ixora spp., Duranta, Nerium, Tecoma stans, Acalypha, Allamanda, and Hydrangea.
Climbers in Garden Design
Climbers have specialized growth habit to cover supports such as pergolas, arches, walls, and trellises.
Major uses:
- Vertical beautification.
- Boundary softening and screening.
- Flowering accents in small spaces.
Common climbers: Bougainvillea spp., Quisqualis indica, Thunbergia grandiflora, Antigonon leptopus, and Allamanda cathartica.
Palms in Landscaping
Palms are valued for architectural form and tropical effect.
Main groups used in ornamental horticulture:
- Pinnate (feather-leaved) palms.
- Fan-leaved palms.
Selected examples:
- Cocos nucifera (coconut palm).
- Areca catechu (arecanut palm).
- Chrysalidocarpus lutescens (areca palm for interiors/exteriors).
- Borassus flabellifer (palmyra).
- Washingtonia spp. and Livistona spp. for avenues and specimen planting.
House Plants / Indoor Plants
Indoor plants are used for interior decoration and can contribute to improved indoor environmental quality.
Practical selection criteria:
- Tolerance to low or filtered light.
- Slow to moderate growth habit.
- Attractive foliage and compact form.
Common indoor choices include Aglaonema, Anthurium, Aralia, Asparagus plumosus, Begonia, Caladium, Codiaeum (crotons), and Coleus.
Summary Cheat Sheet
| Plant group | Primary use | Typical examples |
|---|---|---|
| Trees | Shade, avenue, structure | Delonix, Cassia, Jacaranda, Ficus |
| Shrubs | Borders, year-round display, hedges | Hibiscus, Ixora, Nerium, Duranta |
| Climbers | Vertical coverage, pergolas, walls | Bougainvillea, Quisqualis, Thunbergia |
| Palms | Tropical form, specimen effect | Areca, Cocos, Borassus, Livistona |
| Indoor plants | Interior decor, foliage value | Aglaonema, Anthurium, Begonia |
Quick recall:
- Trees create the permanent framework.
- Shrubs provide middle-layer color and partition.
- Climbers maximize beauty where horizontal space is limited.
- Palms add formal tropical character.
