The seasonal landscape creation of vertical gardens should be combined with the plant growth cycle, color changes, spatial functions and regional climate. Through scientific planning and dynamic adjustment, a visual effect of having scenery in all four seasons and distinct seasonal phases should be achieved. The following analysis is conducted from four dimensions: seasonal characteristics, plant selection, color matching, and maintenance strategies.
Plant selection
Flowering plants: Give priority to varieties that bloom in early spring, such as cherry blossoms (small varieties), tulips (bulbs need to be refrigerated in advance), primroses, and pansies, to form patches of colors like pink, purple, and yellow.
Foliage plants: Paired with colorful leaf varieties that sprout new leaves, such as Red Maple (with red tender leaves in spring), variegated Rhododendron (with pinkish edges on new leaves), and Vitriol (with bright leaf colors in spring).
Climbing plants: Plant ivy and Cleatis (early-flowering varieties), and take advantage of their rapid growth characteristics to cover blank areas.
Landscape design strategy
Color contrast: Plant warm-toned flowers (such as tulips) and cool-toned foliage plants (such as blue fescue) alternately to enhance the visual impact.
Layering: The upper layer is planted with tall flowers (such as lupan beans), the middle layer is paired with low flower beds (such as pansies), and the lower layer is covered with ground cover plants (such as February lilies).
Dynamic adjustment: Gradually replace early spring flowers in the middle of spring and supplement summer flowering plants (such as petunias) to extend the flowering period.
Plant selection
Heat-resistant flowers: Select varieties that bloom continuously under high temperatures, such as blue snowflake (blue series), zinnia (red, yellow, orange), sunflower (multicolored), and jasmine (small white flowers).
Foliage plants: Increase varieties that are sun-tolerant and have thick leaves, such as Sedum lineare (golden yellow), Sedum lineare (pinkish-purple), and Hosta (green-leaf shade-tolerant variety).
Vanilla plants: Add mint, rosemary and lavender as accents. They are heat-resistant and can release fragrances, enhancing the spatial experience.
Landscape design strategy
Cooling colors: The main tones are blue, white and purple (such as blue snowflake + white jasmine), creating a refreshing visual effect.
Shade design: Plant climbing plants (such as trumpet vine and wisteria) on the top of the vertical garden or in certain areas to form a natural shade net.
Water management: Increase the frequency of irrigation in summer and use moisture-retaining materials (such as coconut coir mulch) to reduce water evaporation.
Plant selection
Foliage plants: mainly red, yellow and orange, such as Acer palmatum (deep red), Ginkgo biloba (golden yellow), Nandina officinale (red leaves), and colored-leaf grass (multicolored).
Fruit-bearing plants: Plant fire thorn (red fruit), crabapple (orange-red), and purple pearl (purple fruit) to add fruit embellishment.
Cold-resistant flowers: Supplement chrysanthemums (multicolored) and osmanthus (yellow small flowers) to prolong the autumn flowering period.
Landscape design strategy
Warm tones dominate: Pair red plants (such as Acer palmatum) with yellow plants (such as ginkgo biloba) to create a gradient effect.
Light and shadow utilization: In autumn, the Angle of sunlight is low. Through the variation in the density of plant leaves, dynamic light and shadow are projected onto the wall.
Leaf management: Retain the dead leaves of some deciduous plants (such as Nandina officinosa) to create a natural transition. At the same time, regularly clear the accumulated leaves to prevent mold.
Plant selection
Evergreen plants: Mainly dark green foliage plants, such as nephrofern (shade-tolerant), ivy (cold-resistant), and ilex (red fruit and green leaf).
Cold-resistant flowers: Select a few winter-blooming varieties, such as wintersweet (yellow) and camellia (pink), or use artificial flowers for decoration.
Structural plants: Plant plants with elegant stem shapes, such as red auspicious wood (red branches) and Dragon claw locust (twisted branches), to enhance the sense of lines in the winter landscape.
Landscape design strategy
Minimalism: Reduce the variety of plants, highlighting the deep green of evergreen plants and the linear sense of structural plants.
Lighting design: Install warm LED light strips along the edges of vertical gardens or in the gaps between plants to enhance the visual effect at night.
Artificial plant supplementation: In fully shaded or extremely cold areas, use artificial plants (such as artificial pine branches and red berries) locally to fill the gaps in the winter landscape.
Plant rotation and replanting
Spring replanting: In March and April, clear the dead branches from winter and replant early spring flowers and bulbous plants.
Summer pruning: Prune overly dense branches and leaves from June to July to promote ventilation, and at the same time, replant heat-tolerant flowers.
Autumn update: Remove summer flowers from September to October and replant foliage and fruit-bearing plants.
Winter protection: From November to December, cover plants that are not cold-resistant with cold-proof cloth or move them indoors.
Color and form adjustment
Color transition: Through the changes in plant flowering periods and leaf colors, a natural connection of colors between seasons is achieved (such as pink in spring → blue in summer → red in autumn → green in winter).
Morphological contrast: In spring, lush flower beds are the main feature; in summer, vertical climbing plants are added; in autumn, the structure of branches and trunks is highlighted; and in winter, the plant forms are simplified.
Pests and Diseases and maintenance
Spring prevention: Spray lime sulfur to remove overwintering insect eggs and reduce the pressure of summer pests and diseases.
Summer water control: Avoid irrigation during high-temperature periods to prevent leaf scorching.
Autumn fertilization: Supplement slow-release fertilizer to enhance the cold resistance of plants.
Winter cleaning: Remove fallen leaves and dead branches to prevent the breeding of bacteria.
The northern region
In winter, the proportion of evergreen plants should be extended and the varieties that are not cold-resistant should be reduced.
Add cold-proof measures (such as cold-proof cloth and heating pipelines).
Southern region
Extend the flowering period of heat-tolerant flowers in summer and reduce the proportion of spring flowers.
Add shading and ventilation designs to cope with high temperature and high humidity.
Plateau or arid areas
Give priority to drought-tolerant plants (such as succulents and cacti).
Reduce the frequency of irrigation and adopt drip irrigation and rainwater collection systems.
The seasonal landscape creation of 3D artificial vertical gardens should take the biological characteristics of plants as the core, combine color psychology, spatial aesthetics and regional climate, and achieve the visual effect of having scenery in all four seasons and distinct seasonal phases through scientific planning and dynamic maintenance. The key lies in:
Precise plant selection: Match the characteristics of cold resistance, heat resistance, flower viewing, and leaf viewing according to seasonal requirements.
Dynamic layout adjustment: Through means such as replanting, pruning, and lighting, the continuity and variability of the landscape are achieved.
Strengthen maintenance and management: prevent pests and diseases, apply fertilizers reasonably, and irrigate scientifically to ensure the healthy growth of plants.
Ultimately, vertical gardens will become ecological artworks that integrate architecture and nature, injecting continuous vitality into urban Spaces.
