Chorizema diversifolium, commonly known as Climbing Flame Pea or Variable Flame Pea, is a dazzling Western Australian native pea with vivid orange, pink, and red-toned flowers carried on slender twining or trailing stems. Despite the common name, this is not a rampant climber. It is better understood as a delicate scrambling subshrub that can be trained lightly, allowed to trail, or encouraged to spill beautifully over edges.

In flower, Chorizema diversifolium is pure theatre. The bright pea flowers glow against fresh green foliage, bringing a warm, jewel-like flash of colour to sheltered native gardens, raised beds, rockeries, large pots, and hanging baskets.

This is a plant for gardeners who appreciate uncommon Western Australian natives and are prepared to give them the conditions they deserve: good drainage, shelter from harsh wet conditions, and a position with bright light rather than heavy shade.

Why Grow Chorizema diversifolium?

Chorizema diversifolium is ideal for gardeners who want a smaller native climber or trailing shrub with real flower impact. It brings colour without bulk, making it useful where a large shrub would be too dominant.

It is especially useful for:

Sunny to lightly shaded native garden beds
Training lightly onto low supports
Trailing over low walls or raised beds
Large hanging baskets
Decorative pots and balcony planters
Rockeries and well-drained embankments
Pollinator-friendly native gardens
Collectors of uncommon Western Australian plants

Its growth is slender, graceful, and naturally informal. Use it where its stems can move, trail, or scramble rather than forcing it into a rigid shape.

Chorizema diversifolium Flowers

The flowers of Chorizema diversifolium are its great strength. They are pea-shaped and richly coloured, usually combining shades of orange, pink, red, and warm flame tones. This combination gives the plant its common name, Climbing Flame Pea.

Flowering is generally strongest from late winter through spring into early summer, with Western Australian records noting flowering from August to December. In eastern Australian gardens, the exact timing may shift depending on local climate, winter conditions, and plant position.

The flowers are held in loose clusters along the stems, creating a vivid display without making the plant look heavy or coarse.

Wildlife Value of Chorizema diversifolium

As a native pea, Chorizema diversifolium is valuable for pollinator-friendly gardens. The brightly coloured pea flowers can attract native bees, butterflies, and other pollen-seeking insects when grown in suitable conditions.

It is best used as part of a layered habitat planting, especially with other small native flowering shrubs and perennials that extend the flowering season through the year.

Best Position for Chorizema diversifolium

Plant Chorizema diversifolium in a position with full sun to dappled shade. In hotter inland gardens, protection from harsh afternoon sun may help maintain better foliage and flower quality.

Choose a position with:

Bright light or morning sun
Dappled shade in hotter climates
Excellent drainage
Good airflow
Protection from waterlogging
Shelter from severe frost
Space for stems to trail, scramble, or be lightly supported

This plant is not suited to wet, heavy, poorly drained soil. It will perform best where the root zone stays free-draining and the plant is not exposed to prolonged winter wet.

Soil and Water Requirements

Chorizema diversifolium prefers well-drained soil. Sandy, gravelly, raised, or lightly improved soils are ideal, provided they do not become boggy.

Water regularly while establishing. Once established, it can handle lower-water conditions, but it is not a desert shrub and should not be treated like a hard arid-zone plant. In pots, hanging baskets, and raised beds, it will need more regular watering during hot weather.

For best results:

Plant into freely draining soil
Use raised beds or mounded planting in heavier soil
Avoid waterlogged conditions
Water deeply while establishing
Allow the soil or potting mix to begin drying between watering
Use a native plant fertiliser sparingly if required
Avoid heavy feeding or rich, wet soil

Good drainage is the key to long-term success.

Frost, Heat and Drought Tolerance

Chorizema diversifolium is best grown in mild to warm climates with excellent drainage. It can tolerate some dry conditions once established, but it will usually perform better with occasional deep watering during extended hot, dry weather.

Drought tolerance: Moderate once established, better with occasional deep watering
Frost tolerance: Light frost only; protect from harder frost
Heat tolerance: Good with drainage and some protection in very hot sites
Drainage needs: Essential

In frost-prone areas, plant it in a warm, protected position with winter sun and good airflow.

Pruning Chorizema diversifolium

Pruning helps keep Chorizema diversifolium compact, leafy, and floriferous. Because it has slender twining or trailing stems, it benefits from tip-pruning when young and light shaping after flowering.

Prune after the main flowering period to:

Encourage bushier growth
Reduce legginess
Maintain a neater trailing habit
Improve performance in pots and baskets
Encourage fresh flowering stems
Keep trained plants within bounds

Avoid hard pruning into old bare wood unless the plant is healthy and actively growing.

Growing Chorizema diversifolium in Pots and Hanging Baskets

Chorizema diversifolium is well suited to large pots, hanging baskets, and balcony planters, provided drainage is excellent. Its slender stems can spill over the edge of a container or be guided gently onto a small support.

Use a quality native plant potting mix and a container that drains freely. Do not allow the pot to sit in water. In containers, check moisture regularly during warm weather, as plants in baskets and raised pots dry out more quickly than plants in the ground.

This is one of the better ways to grow Climbing Flame Pea if your garden soil is heavy or poorly drained.

Garden Design Ideas for Chorizema diversifolium

The warm flame-coloured flowers of Chorizema diversifolium combine beautifully with silver, grey, lime-green, and fine-textured native foliage. Its smaller, scrambling habit makes it best suited to the front or edge of a planting, where it can spill naturally rather than compete with large shrubs.

Suitable planting companions include:

Chocolate Lilies
Native daisies and everlastings
Use it in pollinator gardens, raised beds, rockeries, hanging baskets, and sheltered native plantings where bright seasonal colour is wanted without adding a large shrub.

Shipping Note

Sylvaterre ships plants upright in custom-made cardboard boxes so they arrive healthy and ready to thrive, unlike nurseries that ship tubestock lying flat in standard Australia Post boxes.
