Botanical Characteristics of Polyscias Scutellaria

Plant Description

Aralia Fabian is a visually striking plant known for its:

  • Height: In ideal conditions, it can grow up to 10-15 feet (3-4.5 meters) tall indoors. It can kept smaller through pruning
  • Spread: Can reach 3-6 feet (0.9-1.8 meters) wide
  • Growth Rate: Moderate to fast, especially in optimal conditions
  • Lifespan: Perennial, with proper care, it can live for many years

Polyscias Scutellaria has an upright, somewhat tree-like growth. It gives it a distinct appearance. It features a woody stem that becomes more prominent as the plant matures.

Leaf Structure and Appearance

The most distinctive feature of Aralia Fabian is its foliage.

  • The shape is large and rounded, with a slight curve that resembles a shield or a shallow bowl.
  • Size: Leaves can reach 4-8 inches (10-20 cm) in diameter
  • Texture: Glossy and leathery to the touch
  • Color: Deep green, though variegated and purple varieties exist
  • Arrangement: Alternate leaf arrangement along the stems

The edges of the leaves are wavy or have a subtle serrated texture. The leaf surface is usually smooth, with prominent veining.  

Notable Varieties:

  • “Marginata” – features cream or white leaf margins
  • “Balfourii” – has mottled cream and green leaves
  • “Fabian’s Pride” – displays darker green leaves with a more pronounced cup shape

Growth Habits

Aralia Fabian exhibits several interesting growth characteristics:

  1. Vertical Growth: The plant grows upright, forming a slender, tree-like structure.
  2. Branching: Polyscias Scutellaria tends to branch out, creating a fuller appearance.
  3. Leaf Density: Foliage is dense, especially at the top of the plant.
  4. Root System: Develop a robust root system that can become pot-bound. It will need repotting.

Aralia Fabian can grow quite tall and develop a more tree-like form. When grown indoors or as a container plant, its growth is restrained.  It can be further controlled through regular pruning.

Flowering and Fruiting

Aralia Fabian is grown for its foliage. It can produce flowers and fruits under certain conditions:

  • Flowers: Small, greenish-white flowers may appear on mature plants in their natural habitat
  • Blooming Season: Typically in summer, though flowering is rare in indoor specimens
  • Fruits: Small, round berries may follow the flowers. But, they are seldom seen on cultivated plants.

Note that flowering and fruiting are not common in indoor Polyscias Scutellaria plants. The energy of the plant is directed towards foliage growth.

Cultivating Aralia Fabian at Home

Light Requirements

The right amount of light is crucial for the health and growth of your Polyscias Scutellaria:

  • Optimal light conditions:
    • Bright, indirect light is ideal
    • Can tolerate moderate to low light, but growth may slow
    • Avoid harsh, direct sunlight, especially during peak afternoon hours
  • Light intensity guide:
    • 70-85% shade is optimal for outdoor plants
    • For indoor plants, place near an east or north-facing window

Dealing with low light situations:

  1. Use artificial grow lights to supplement natural light
  2. Rotate the plant to ensure even growth
  3. Consider variegated varieties, which often tolerate lower light better

Watering Needs

Proper watering is essential for maintaining a healthy Aralia Fabian:

  • Frequency of watering:
    • Water when the top 1-2 inches (2.5-5 cm) of soil feels dry
    • This means watering once or twice a week
    • Reduce watering frequency in winter when growth slows
  • Watering technique:
    • Water until it drains from the bottom of the pot
    • Empty the drainage tray to prevent water stagnation

Signs of overwatering:

  • Yellowing leaves
  • Soft, mushy stems
  • Mold on soil surface

Signs of underwatering:

  • Drooping or wilting leaves
  • Dry, crispy leaf edges
  • Slow growth

Remember: It’s better to underwater than to overwater. Aralia Fabian is more tolerant of short dry spells than prolonged wet conditions.

Soil and Potting

The right soil mix and potting practices are important for the health of your plant:

Ideal soil composition:

  • Well-draining potting mix
  • Rich in organic matter
  • pH range of 6.1 to 7.5 (acidic to neutral)

Potting mix recipe:

  • 2 parts quality potting soil
  • 1 part perlite or coarse sand
  • 1 part peat moss or coco coir

Repotting frequency and process:

  1. Repot every 2-3 years or when rootbound
  2. Choose a pot 1-2 inches (2.5-5 cm) larger in diameter
  3. Ensure the new pot has adequate drainage holes
  4. Loosen roots when repotting to encourage new growth

Pro tip: Add a layer of orchid bark to the bottom of the pot to improve drainage and aeration.

Temperature and Humidity

Aralia Fabian thrives in conditions like its tropical origin:

Optimal temperature range:

  • Daytime: 70-85°F (21-29°C)
  • Nighttime: Not below 60°F (15°C)
  • Can tolerate brief periods down to 50°F (10°C), but not recommended

Humidity requirements:

  • Prefers high humidity (60-80%)
  • Can adapt to average household humidity, but will appreciate extra moisture

Methods to increase humidity:

  1. Use a pebble tray filled with water
  2. Group plants together to create a microclimate
  3. Mist leaves in the morning
  4. Use a room humidifier

Caution: Avoid placing your Aralia Fabian near heating vents or air conditioning units. They can cause temperature fluctuations and dry air.

Fertilization

Proper fertilization ensures your Polyscias Scutellaria maintains lush, healthy growth:

Types of fertilizers suitable for Aralia Fabian:

  • Balanced, water-soluble fertilizer (e.g., 10-10-10)
  • Slow-release granular fertilizer
  • Organic options like fish emulsion or seaweed extract

Fertilization schedule:

  • Feed every 2-4 weeks during the growing season (spring and summer)
  • Reduce or stop fertilization in fall and winter
  • Always follow package instructions for dosage

Pro tip: If using a liquid fertilizer, apply it to moist soil to prevent root burn.

Pruning and Shaping Polyscias Scutellaria

Prune and shape to maintain the health of your Aralia Fabian (Polyscias Scutellaria). These practices control the plant’s size, promoting bushier growth and attractive form.

When to Prune

  • Best season: Early spring, before the active growing season begins
  • Frequency: 1-2 times per year for maintenance, more for shaping
  • Growth indicators: Prune when the plant becomes leggy or too tall for its space

Note: Spring pruning is ideal. Light pruning year-round if necessary to remove damaged or diseased parts.

Techniques for Shaping

Shaping your Polyscias Scutellaria helps maintain its compact form and encourage fuller growth:

  1. Pinching:
    1. Pinch off new growth at the tips of branches to encourage branching
    1. Use your thumb and forefinger to remove the soft, new growth
  2. Heading back:
    1. Cut back longer branches to a leaf node or bud
    1. This technique helps control height and promotes bushier growth
  3. Thinning:
    1. Remove entire branches back to the main stem
    1. Improves air circulation and light penetration within the plant
  4. Crown reduction:
    1. Reduce the size of the plant by cutting back the main stems
    1. Use this technique only when necessary

Pro tip: Always make cuts at a 45-degree angle. Cut above a leaf node to promote healing and prevent water from pooling on the cut surface.

Tools Needed

Having the right tools ensures clean cuts and reduces the risk of damage or disease:

  1. Pruning shears: For small branches up to 1/4 inch in diameter
  2. Loppers: For thicker branches up to 1 inch in diameter
  3. Pruning saw: For rare cases when you need to remove very thick, woody stems
  4. Disinfectant: Isopropyl alcohol or a diluted bleach solution to sterilize tools between cuts

Important: Always clean and sterilize your tools before and after use. This will prevent the spread of diseases.
