Perfect for damp borders, woodland planting and pond-side gardens, this eye-catching perennial delivers long-lasting colour from spring until autumn.

Why Grow Houttuynia 'Flame'?

This distinctive plant offers:

✅ Brilliant multi-coloured foliage

✅ Excellent ground-cover potential

✅ Thrives in damp or moisture-retentive soils

✅ Grows well in shade and partial shade

✅ Useful for difficult garden areas

✅ Easy to maintain once established

While grown mainly for its foliage, small white flowers also appear during summer, providing additional interest.

Best Position for Houttuynia 'Flame'

For the healthiest growth and strongest colour, plant in:

• Partial shade
• Dappled woodland shade
• Moist borders
• Pond-side planting schemes

It will tolerate more sun if soil moisture is maintained, but partial shade usually produces the freshest foliage and best overall performance.

Soil Requirements

Houttuynia enjoys:

• Moist soil
• Fertile ground
• Organic-rich conditions
• Neutral to slightly acidic soils

Before planting, improve the area with plenty of compost or leaf mould to help retain moisture.

Unlike many perennials, Houttuynia is happy in areas where soil remains consistently damp.

Watering

This plant performs best when soil never completely dries out.

During prolonged dry weather:

• Water regularly
• Mulch around plants
• Monitor container-grown specimens closely

Once established, plants become relatively resilient but still appreciate reliable moisture.

Understanding Its Spreading Habit

One important consideration is its spreading nature.

Although 'Flame' is often considered more manageable than some forms of Houttuynia, it can still spread through underground rhizomes in favourable conditions.

For gardeners wanting complete control:

• Grow in large containers
• Install root barriers
• Use sunken pots in borders

This makes it easier to enjoy the colourful foliage without concerns about unwanted spreading.

Growing in Containers

Houttuynia 'Flame' performs exceptionally well in pots.

Benefits include:

• Easier spread control
• Bright patio displays
• Greater flexibility in positioning
• Simple winter maintenance

Use a moisture-retentive compost and avoid allowing containers to dry out completely.

Feeding

This is not a particularly hungry plant.

Apply:

• A balanced slow-release fertiliser in spring
• Compost or leaf mould as an annual mulch

Overfeeding can encourage excessive growth and reduce the intensity of foliage colour.

Winter Care

Houttuynia 'Flame' is fully hardy throughout most of the UK.

As temperatures cool:

1. Foliage naturally dies back.
2. Remove old stems in late winter.
3. Apply a light mulch if desired.
4. Wait for fresh shoots to emerge in spring.

The plant reliably returns year after year.

Common Problems

Fortunately, issues are relatively rare.

Slugs and Snails

Young spring growth may attract:

• Slugs
• Snails

Protection is most important while new shoots are emerging.

Dry Conditions

Poor growth and faded foliage colour are usually caused by soil drying out for extended periods.

Overcrowding

Allow reasonable airflow around plants to help prevent occasional fungal problems.

Companion Plants

Houttuynia 'Flame' combines beautifully with other moisture-loving and shade-tolerant plants such as:

• Hostas
• Ferns
• Astilbes
• Ligularia
• Rodgersia
• Brunnera
• Japanese Anemones

These combinations create attractive foliage contrasts and provide interest throughout the growing season.

Where to Use Houttuynia 'Flame'

This versatile perennial works particularly well in:

• Woodland gardens
• Pond margins
• Damp borders
• Shade gardens
• Courtyard planting
• Foliage-focused displays
• Container gardens

Its vibrant foliage helps brighten areas where flowering plants can sometimes struggle.
