Tradescantia pallida 'Purple Heart', commonly known as Purple Heart, is a fast-growing trailing plant loved for its vibrant purple foliage and easy-going nature. Native to eastern Mexico, this striking variety features long, fleshy stems covered in deep violet leaves that become even more intensely coloured in bright light.

Its trailing habit makes it an excellent choice for hanging baskets, shelves and mixed planters, while its ability to spread quickly also makes it a popular ground cover in warmer climates. Throughout the growing season, Purple Heart produces delicate three-petalled pink flowers that provide a beautiful contrast against its rich purple foliage.

Easy to grow and highly adaptable, Tradescantia 'Purple Heart' is an excellent choice for beginners and experienced houseplant enthusiasts alike.

Tradescantia 'Purple Heart' Care Guide

Light

Purple Heart develops its richest colour in bright conditions.

• Bright, indirect light is ideal.
• A few hours of gentle morning or late afternoon sun will intensify the purple foliage.
• Tolerates medium light but the leaves may become greener and less vibrant.
• Avoid prolonged harsh midday sunlight through glass, which may scorch the foliage.

For the deepest purple colour, place your plant in a bright position with filtered sunlight.

Watering

Tradescantia 'Purple Heart' prefers evenly moist compost but dislikes sitting in water.

Allow the top 2–3cm of soil to dry before watering again.

During spring and summer:

• Water approximately once a week, adjusting according to temperature and light levels.

During autumn and winter:

• Reduce watering to every 10–14 days or when the compost has partially dried.

Always allow excess water to drain freely.

Signs of overwatering

• Yellow leaves
• Soft stems
• Root rot
• Leaf drop

Signs of underwatering

• Dry, crispy leaf edges
• Wilting stems
• Slower growth

Humidity

Purple Heart adapts well to average household humidity.

Ideal humidity:

• 40–60%

It also benefits from slightly higher humidity but generally performs well in most indoor environments.

Temperature

Ideal temperatures range from:

18°C–27°C

Avoid temperatures below:

10°C

Protect from:

• Frost
• Cold draughts
• Sudden temperature changes

Soil

Use a light, well-draining compost.

A suitable mix includes:

• Houseplant compost

Good drainage helps prevent root rot.

Feeding

Feed during active growth:

• Use a balanced liquid houseplant fertiliser at half strength.
• Stop feeding during winter.

Repotting

Purple Heart grows quickly and may require repotting every:

• 1–2 years
• Or when roots become crowded.

Choose a pot only one size larger to prevent excess moisture retention.

Pruning

Regular pruning encourages fuller, bushier growth.

You can:

• Pinch out growing tips.
• Remove leggy stems.
• Trim long trailing shoots to maintain a compact shape.

Frequent trimming encourages new side shoots and denser growth.

Cleaning

The smooth leaves rarely collect much dust.

If required:

• Gently wipe leaves with a damp cloth.
• Rinse occasionally with lukewarm water.

Avoid leaf shine products.

Propagation

Tradescantia 'Purple Heart' is extremely easy to propagate.

Simply:

• Take a healthy stem cutting with several nodes.

• Roots usually develop within 1–2 weeks.

This makes it one of the easiest houseplants to multiply.
