The Chinese Myrtle (Murraya paniculata), also commonly known as Orange Jasmine, is a popular tropical and sub-tropical species for bonsai, highly valued for its dense, glossy dark green foliage, delicate white flowers, and small, attractive red fruits.
The pot choice for the Chinese Myrtle must reflect its elegant, feminine, and tropical aesthetic while addressing its specific horticultural needs.
Here is an extensive and detailed guide to choosing the perfect ceramic pot for your Chinese Myrtle bonsai tree.
The Chinese Myrtle's Defining Characteristics
The ideal pot choice is dictated by the tree's unique visual and growth characteristics:
- Feminine and Elegant Aesthetic: The Chinese Myrtle typically develops smooth, pale bark and displays fine, dense ramification with small, delicate leaves and flowers. It is rarely styled to look rugged or masculine.
- Pot Impact: The pot should be refined, often featuring gentle curves, subtle colours, and a glazed finish to enhance its elegance.
- Small Leaves and Flowers: Its naturally small leaves and profusion of tiny, fragrant white flowers create a soft, cloud-like canopy.
- Pot Impact: The pot should be proportional to the small scale of the foliage and must not overpower the delicate flowers.
- Tropical Water Needs: As a tropical species, it thrives on warmth and high humidity. It needs to be watered regularly and must never dry out completely, but it also cannot tolerate constantly waterlogged soil.
- Pot Impact: Excellent drainage is necessary, but unlike pines, it can often handle a slightly deeper pot to buffer against rapid drying, especially if it lives indoors or in a greenhouse.
Functional Considerations: Health and Stability
For a tropical tree, the pot's structure is paramount for maintaining a stable environment.
1. Material and Finish: Glazed is Preferred
Unlike hardy temperate species, the Chinese Myrtle is typically paired with a glazed pot.
- Aesthetic Reason: The smooth, often refined surface of a glazed pot harmonises beautifully with the glossy leaves, delicate flowers, and smooth, pale trunk of the Myrtle. It adds a touch of sophistication appropriate for the species.
- Horticultural Reason: Since the Chinese Myrtle often requires stable moisture levels, the non-porous nature of a glazed pot can help slow down the evaporation of moisture through the pot walls, which is beneficial in warmer, drier indoor or greenhouse environments.
- Exception (Unglazed): If you opt for unglazed, choose a high-fired clay in a light, refined earth tone (e.g., pale grey, cream, or beige) to maintain the elegant feel.
2. Drainage and Winterising
- Drainage Holes: Large, sufficient drainage holes are essential. Even though the Myrtle likes moisture, water must flow freely to prevent stagnant conditions and root rot.
- Tie-Down Holes: Needed to secure the tree, particularly important if the tree is frequently moved in and out of a greenhouse or living space.
- Frost Resistance: Since this is a tropical species, the pot will usually not face frost. The focus should instead be on a high-quality glaze and even firing to ensure stability.
3. Size and Depth Proportions
The pot should be proportional to the tree's overall height and mass, while ensuring sufficient soil volume for the active tropical roots.
Proportion
Guideline
Chinese Myrtle Application
Length/Width
The pot's length should be approximately $\frac{2}{3}$ of the tree's height.
Standard reliable rule.
Depth
The pot's depth is often equal to the diameter of the trunk (Nebari).
A slightly deeper-than-average pot is often beneficial for tropical species like the Myrtle to provide stability for active root growth and to help buffer moisture levels, preventing the soil from drying out too quickly.
Visual Weight
Due to its fine foliage and slender trunk, the Myrtle generally looks best in a pot with thin-to-medium walls and a delicate lip, avoiding heavy, chunky rims.
Aesthetic Considerations: Color and Shape
The pot should complement the tree's fine details without overpowering the small flowers.
1. Pot Shape: Matching the Style
The Chinese Myrtle is versatile and can be styled in almost any form, but it excels in graceful, feminine styles.
- Informal Upright (Moyogi) or Slanting (Shakan):
- Oval: The most popular choice. A gentle oval shape enhances the tree's fluid lines and conveys elegance. A deeper oval is often preferred.
- Rectangle with Rounded Corners: Provides the stability of a rectangle but with softer edges that suit the Myrtle's grace.
- Cascade/Semi-Cascade:
- Requires a tall, round, or hexagonal cascade pot to balance the downward-moving structure. These are usually in subtle colors.
- Broom Style (Hokidachi):
- A shallow, round pot is the classic pairing for this very formal, triangular style.
2. Colour: Enhancing the Blooms and Foliage
The color choice should highlight the brilliant white flowers, glossy green leaves, and delicate red fruits.
- Subtle & Pastel Glazes (Recommended): These are the best choices for flowering and fruiting trees as they do not compete with the tree's display.
- Soft Greens (Celadon, Jade): Harmonises with the foliage beautifully and allows the white flowers to stand out.
- Pale Creams, Yellows, or Beiges: These neutral tones are classic and elegant, offering a clean, simple backdrop.
- Contrasting Glazes (Effective):
- Deep Matte Blue: A rich cobalt or navy blue provides a stunning, deep backdrop that makes the white flowers and glossy green foliage truly pop. This is a popular and striking choice.
- Avoid: Bright reds, oranges, or multi-coloured, busy glazes, as these will overwhelm the subtle beauty of the white flowers and fine ramification.
