Thuja orientalis 'Aurea Nana': The Golden Gem of Gardens

If you are looking for a plant that brings structure, color, and year-round beauty to your workspace, look no further than the Thuja orientalis 'Aurea Nana'. At our office garden in Battambang, Cambodia, this stunning evergreen has become a focal point, proving that you don't need a massive landscape to enjoy high-quality greenery.

Commonly known as the Golden Dwarf Biota or Oriental Arborvitae, this plant is a slow-growing conifer that is perfectly suited for the tropical climate of Southeast Asia.

​

What Makes 'Aurea Nana' Unique?

The 'Aurea Nana' is beloved by gardeners for its distinct characteristics:

• Distinctive Shape: It naturally grows in a neat, compact, and globe-like or egg-shaped form. Unlike other trees that require constant pruning, this Thuja stays tidy on its own.

  
  

• Color Transformation: The foliage consists of flat, fan-like sprays. In the bright Battambang sun, the outer tips turn a brilliant golden-yellow, while the interior remains a lush, deep green.

  
  

• Vertical Texture: The branches grow in vertical planes, giving the plant a unique "book-leaf" appearance that adds a sophisticated texture to any pot or garden bed.

Growing Thuja in Cambodia: Expert Care Tips

While this plant is hardy, the intense heat of Cambodia requires a few specific care steps to keep it looking its best:

1. Sunlight is Essential

To maintain that famous "Golden" glow, the 'Aurea Nana' needs full sun to bright indirect light. If kept in too much shade, the plant will lose its golden hue and turn a plain green.

2. Mastering the Water Schedule

In our Battambang office garden, we pay close attention to the soil.

• Drainage: It is crucial that your pot has good drainage holes.

• Consistency: Keep the soil moist but never waterlogged. During the dry season, check the pot daily; if the top inch of soil feels dry, it’s time to water.

  
  

3. Soil and Fertilization

Use a well-draining potting mix. A light application of balanced fertilizer during the growing season will help the plant maintain its density and vibrant color.

4. Heat Management

While it loves the sun, the extremely high temperatures in mid-April can be stressful for potted plants. If the foliage looks a bit dull, a morning misting can help cool the plant down and clean off any dust.

Why It’s Perfect for Your Office Garden

The Thuja orientalis 'Aurea Nana' is the ultimate "low-maintenance, high-reward" plant. It doesn't drop messy leaves, it rarely suffers from pests if kept healthy, and it provides a sense of permanence and "Plant Joy" throughout every season.
