What is the honey flower like?Melianthus major)?
Melianthus major is an evergreen shrub native to South Africa, where it grows naturally in sunny, dry areas, often near ditches or drainage ditches. In ornamental gardening, can reach between 2 and 3 meters in height, with a size that can easily extend more than 2 meters wide, ideal for forming groups of shrubs, flowerbeds or covering slopes.
Its leaves are pinnate, large, bluish-green or greyish in colour and with deeply serrated margins.These leaves, which can grow between 30 and 50 centimeters long, are composed of numerous leaflets with a slightly silky texture and a very attractive glaucous hue. They are alternate, odd-pinnate, and when crushed, give off a characteristic and somewhat unpleasant odor, although their main use is ornamental.
The flowers are grouped in erect spikes They can measure between 30 and 90 centimeters long. They are tubular, red to maroon in color, highly melliferous, and give off an intense honey scent, which attracts a multitude of bees and pollinators. Flowering usually occurs in spring, extending into summer, and can even repeat in autumn in warm climates.
The name of Melianthus comes from greek meli (honey) and anthos (flower), referring to both the aroma and the nectar, which is the only non-toxic part of the plant, even used as a sweetener in some regions.
Important warning: All parts of the honeysuckle flower, except for the nectar of its flowers, are poisonous if ingested, both for people and pets. It is advisable to plant this shrub out of the reach of small children and pets.
Main botanical characteristics of Melianthus major
- Ports: Evergreen shrub, fast growing, 2 to 3 meters tall and up to 3 meters wide.
- Sheets: Large, pinnate, blue-green, serrated margin, alternate, silky texture, characteristic odor.
- Flowers: Erect spikes or terminal clusters of deep red or maroon color, tubular flowers, honey aroma, very attractive to bees.
- Flowering: Mainly in spring and into summer; possible second flowering in autumn in mild climates.

Where and how to use honeysuckle in the garden?
- It stands out as an architectural plan for its appearance and the contrast between its foliage and its flowers.
- Ideal for sunny, low-maintenance Mediterranean gardens with medium to low water requirements.
- It is used in borders, flowerbeds, next to walls, to cover slopes, form flowerbeds, and also in large pots or containers on patios and terraces.
- It provides color and structure throughout the year thanks to its evergreen foliage and prolonged flowering.
- It works very well combined with ornamental grasses or plants with smaller leaves, achieving interesting contrasts in texture and color.
In summer, its foliage may droop slightly, but in autumn the plant sends out new shoots and can stand out for the color of its foliage during the winter, especially in temperate climates.
To consider: The nectar of the honeysuckle flower can be collected and used as a natural sweetener, but other parts of the plant should never be consumed due to their toxicity.
Detailed care of the honey flower (Melianthus major)
ideal location
The honey flower is a flexible plant in terms of location, although prefers to be in full sun to develop in all its splendor. It can tolerate light shade, especially in places with very hot summers. In these situations, the important thing is that it receives plenty of daylight so that the blue color of its leaves and the vigor of its flowering are not affected.
Substrate and soil type
- Potted: Use enriched, well-draining universal potting soil. Adding a layer of volcanic clay or arlite to the base ensures water doesn't accumulate and prevents root rot. An occasional addition of organic matter will help maintain fertility.
- In the garden: It tolerates a wide variety of soils, as long as drain well Water. In very compact or clayey soils, it is recommended to mix the soil with coarse sand or perlite. It prefers neutral to slightly acidic soils, but adapts to alkaline conditions.
To achieve optimal growth, it is important to avoid waterlogged or poorly aerated soils, as this causes fungal problems and weakens the plant.
Irrigation
The honey flower is relatively resistant to drought., but it needs regular watering, especially while it is actively growing or flowering. In summer, water 3 to 4 times a week, ensuring the substrate is deeply moistened. As temperatures drop, gradually space out watering and keep the soil only slightly moist in winter.
- It is important: Let the top layer of the substrate dry between waterings and avoid waterlogging. In a pot with a saucer, remove excess water after each watering.
- Ability to withstand short periods of drought: Once established, honeysuckle can withstand a few days without watering, although water stress can affect flowering.
Subscriber
The subscriber is key to obtaining abundant flowers and vigorous leaves. Fertilize from early spring to late summer, using organic products such as compost, well-rotted manure, or worm castings. If you grow the plant in a pot, choose liquid or stick fertilizers, as granular fertilizers can clog drainage.
- During the flowering season, a monthly application of fertilizer rich in potassium and nutrients will promote the production of showy flowers.
- Maintain a good balance of organic matter in the soil to stimulate healthy growth and prevent nutritional deficiencies.
Pruning
Pruning in Melianthus major It is simple, but essential to maintain a compact appearance and stimulate regrowth:
- Light pruning: Do this after flowering to remove dry flower stems and damaged leaves.
- Intense pruning: In adult specimens or when the plant loses vigor, it can be cut back to the base in late winter, encouraging new shoots to appear in spring.
- Tip: Don't cut back to ground level every year, as flowers usually appear on second-year wood; if you remove too much, you may miss the next season's bloom.
Multiplication and propagation
Propagation is simple:
- By seeds: Sow in spring in pots or trays, 1-2 seeds per hole and using light soil. Keep in a warm, sunny location, watering sparingly. Germination takes 3-4 weeks if fresh.
- By basal or softwood cuttings: Cut young stems or basal stems in early spring or summer. Plant in moist soil and keep in a bright environment but away from direct sunlight. They root easily.
- By division of bush: Separate rhizomes with shoots in autumn or early spring and replant.
Hardiness and cold resistance
Melianthus major can withstand temperatures down to -8 ºC once it is well established, although Young specimens should be protected from severe frost.In very cold climates, it's recommended to grow in a pot and protect it during the winter. If vegetative parts are damaged by freezing temperatures, the plant usually sprouts from the base in spring.
In Mediterranean and coastal regions, it can grow outdoors year-round. In areas with harsher winters, use mulch or padding to protect the base and roots.
Common pests and diseases
Honey flower is resistant to most common pests. However, the following may appear:
- Slugs and snails: They attack young leaves.
- Red spider: Especially under greenhouses or in dry, poorly ventilated conditions.
- Whitefly and aphid: Uncommon, but possible if there are moisture imbalances or excess nitrogen fertilization.
- Fungi due to excess humidity: It may suffer from root rot if the substrate does not drain well.
Proper irrigation and ventilation prevent most of these problems. To control pests like slugs and snails, remove them manually or use organic methods.
Secrets and advanced tips for growing honeysuckle flowers
- Long flowering: To maximize flowering time, avoid drastic pruning in late winter and maintain balanced nutrition.
- Use in pots: Growing in large containers allows you to control growth and relocate the plant if temperatures drop too low.
- Landscape combinations: The silvery-blue color of its leaves is ideal for contrasting with plants with darker foliage or yellow and orange blooms.
- Spontaneous regrowth: In autumn, young plants may appear near the mother plant due to seeds or rhizomes, which facilitates their multiplication.
- Toxicity management: Despite its beauty, it is important to label the plant in gardens where children or animals are present, and never use plant remains in home compost intended for gardening or human consumption.
Ecological utility: Honey-bearing inflorescences are an excellent resource for pollinators, especially bees, contributing to local biodiversity and the balance of garden ecosystems.
Main ornamental and practical uses
- Focal point in gardens and patios.
- Formation of shrubby groups, isolated or combined with other species.
- Coverage of slopes and areas that are difficult due to their rapid development.
- Grown in large pots for terraces and greenhouses.
- Nectar extraction as a natural sweetener (only flower nectar, never other parts of the plant).
Honeysuckle is especially appreciated in Mediterranean-inspired gardens and temperate climates, where it stands out as a hardy, unique, and low-maintenance option.
The spectacular nature of the honeysuckle flower lies both in its architectural structure and in the contrast between its foliage and the flower spikes. Its cultivation is straightforward, and its presence adds an exotic and vibrant touch to any green space, making it an indispensable ally for modern, sustainable gardens.
