Leonotis leonurus: The South African Diva That Transforms Tired Borders

This South African diva wakes it up - radically.

Many gardens in German-speaking regions look neat but somewhat interchangeable. A crisp lawn edge, easy-care perennials and perhaps a few roses: pleasant, but lacking a true wow factor. This is precisely where a plant that remains largely unknown here comes in, despite long circulating as an insider tip in designer gardens: Leonotis leonurus, also known as lion’s ear.

The living flame sculpture for tired borders

Leonotis leonurus is one of those perennials you see once and never forget. Native to South Africa, it looks as though a graphic designer had drafted it: rigidly upright shoots reaching around 1.80 m, topped tier upon tier with vivid orange flower whorls.

Leonotis resembles a living candelabrum in a border: every flowering tier forms a ring of orange flames.

Its flowers are tubular, slightly hairy and packed into dense rings around the stems. At full bloom, they resemble stylised flames - almost a Pop Art sculpture placed in the middle of the garden. The narrow, elongated foliage reinforces this graphic quality: nothing bulky or clumsy, but a slender, upright outline.

Anyone used to rounded or cushion-forming perennials will notice the difference immediately: Leonotis brings height into the planting. It rises well above neighbouring plants and naturally draws the eye upwards. This vertical accent gives even small urban gardens greater depth.

A firework for people - a buffet for insects

While the brilliant orange shades look spectacular to us, they mean one thing above all to insects: an invitation. The tubular flowers provide plenty of nectar. During summer, Leonotis is surrounded by constant activity, with solitary bees, honeybees, hoverflies and butterflies using it as a regular feeding stop.

In its warmer native countries, hummingbirds even visit the flowers; here, butterflies and bees take over as the regular guests. Anyone wanting an ornamental border that is not only attractive but also insect-friendly therefore gets two benefits from Leonotis.

Position: where Leonotis leonurus can show off at its best

As striking as this plant appears, its requirements are equally clear: it loves sunshine. Not merely “bright partial shade”, but genuinely full, intense light.

The more sun Leonotis receives, the taller and more floriferous it becomes - six hours of direct light is the minimum.

An ideal position offers:

• at least six hours of direct sunshine each day
• free-draining, relatively light soil
• no winter waterlogging
• some protection from wind so the tall shoots do not snap

The soil can certainly be nutrient-rich, but it needs to shed water quickly. Heavy clay soil can be opened up with sand or grit. If the front garden contains only compacted construction soil, loosen it deeply before planting and improve it with compost.

A drought performer with one weak point

Once properly established, Leonotis copes remarkably well with dry spells. This makes it especially interesting for areas where summers are becoming hotter and less rainy. Planted in the ground, it can manage extended periods without watering, provided it has not only just been planted.

It tolerates temperatures down to around −8 °C if the site is not completely exposed. A thick winter covering of leaves or straw over the root area helps the perennial through cold nights. In locations particularly prone to frost, it is worth growing it in a pot that can be moved into a frost-free shed or bright stairwell on cold days.

The 5 golden rules for planting Leonotis

Plant in spring and there is a good chance of enjoying the first floral display in summer. A few basic rules are crucial:

• Choose a genuinely sunny spot: Ensure at least six hours of sunshine; otherwise, the plant remains short and flowers sparsely.
• Make sure the soil drains well: Work in sand, grit or fine gravel to prevent water from sitting in the ground over winter.
• Start with compost: When planting, add a portion of mature compost or high-quality, structurally stable planting compost.
• Water moderately after planting: Water regularly at first, then less often - this perennial handles drought better than wet feet.
• Mulch outdoor plants: Before winter, apply a generous layer of mulch over the root zone, particularly in exposed areas.

For pots, choose a fairly tall, sturdy container so the shoots, which can reach 1.80 m, do not topple over. Do not forget a drainage layer of expanded clay or gravel at the base.

How Leonotis becomes the star of the perennial border

Leonotis is not a plant for the edge of a border. It makes its strongest impact in the middle or rear, framed by lower-growing companions. Its orange flower whorls combine exceptionally well with cool blue and violet tones.

Effect	Planting partners
Modern, graphic look	Ornamental grasses (Pennisetum, Miscanthus), grey-leaved perennials
Fiery summer mix	Dark-leaved dahlias, bronze-leaved cannas, red gaura
Naturalistic garden	Blue and purple Salvia, Echinacea, Rudbeckia
Urban design border	Structural grasses, few varieties planted in larger groups

As a bright, vertical accent, Leonotis tells a story in the border - it performs like a leading character with a powerful presence.

For a calm but never dull effect, plant Leonotis in a sea of airy grasses. The soft blades create a backdrop from which the orange floral garlands stand out clearly. Even in small gardens, a group of just three plants is enough to achieve this result.

Border ideas for different garden styles

One example for a 3-metre border beside a terrace:

• 3 x Leonotis in the rear section, planted in a staggered arrangement
• 5–7 x blue Salvia in front of the Leonotis perennials
• 3 x dark-leaved dahlias or cannas for contrast
• loosely scattered throughout: low ornamental millet or fountain grass

For fans of naturalistic gardens, Leonotis works well beside a fence or in front of a loosely planted hedge. Place Echinacea and Rudbeckia in front, with wild perennials such as dyer’s chamomile or yarrow between them. The result looks spontaneous while still being deliberately composed.

Care through the year: little effort, major impact

Despite its dramatic appearance, Leonotis is not one of those demanding prima donnas. Plant it correctly from the outset and it requires little work afterwards.

• Spring: Cut back old shoots once the danger of severe frost has passed. Give a light initial feed with compost.
• Summer: Water only during prolonged drought. Spent tiers can be removed, although this does not always encourage another flush of flowers - many gardeners simply leave the decorative whorls in place.
• Autumn: In colder regions, leave the lower parts of the stems standing and thin them out only gently. Save hard pruning for spring.
• Winter: Check the mulch layer and, during severe bare frosts, add an extra covering of brushwood.

Disease is uncommon as long as the soil drains freely. Problems arise only when the plant sits in wet ground for weeks, as the root base may then rot. Aphids and other sap-sucking pests are more likely during dry periods of stress. A strong jet of water and more disciplined watering are usually sufficient remedies.

Who benefits most from growing Leonotis

Leonotis is particularly appealing to gardeners who want to create a noticeably more modern look with little effort. Anyone who has previously relied chiefly on traditional cottage-garden plants or low-maintenance ground cover gains an immediate stylistic break from this perennial - in the best possible sense.

Leonotis also has advantages on balconies and roof terraces. In a sufficiently large container, combined with ornamental grasses and blue Salvia, it looks like a complete, moveable design border. Its drought tolerance is especially valuable in places where watering every week is not desirable.

The principal risks occur in very frosty areas and on exceptionally heavy soils. Anyone gardening in a cool Alpine valley or on a windy ridge should treat Leonotis more as a container plant. In mild wine-growing regions or inner-city locations, however, there is a good chance that the perennial will last for several years.

How Leonotis can shape your garden over time

Once this plant is in the border, it soon becomes clear how powerfully it changes the feel of the entire space. Many gardeners then begin adding further vertical features: taller grasses, bistort and tall salvias. Gradually, this creates a layered garden picture with clear drama, close to the trend for so-called “New Perennial” borders.

There is another appealing effect: the taller structure keeps the garden lively even in late summer and early autumn, when many classic flowering plants are already beginning to fade. Leonotis’s orange tiers, paired with mature grasses and the seedheads of other perennials, create an atmosphere reminiscent of southern landscapes without looking artificial.

Anyone keen to take a chance can test-plant Leonotis in a prominent spot this spring. A dull edge border or a gap in front of a monotonous hedge is ideal. Often, one brief look on a hot day in July is enough to realise that this “unknown orange” has what it takes to become a new favourite plant.
