There are about 20 species within the Duranta genus, including Duranta mutisii, Duranta serratifolia, and Duranta dombeyana.
The bush has a upright and branched bearing, with vigorous main trunks, arched branches and, frequently, axillary spines (more noticeable in adult specimens). Its growth is rapid, forming in a short time a leafy and compact mass with opposite leaves, simple, elliptical or ovoid in shape, with the margin toothed in the upper half. The color of the leaves ranges from intense green with yellowish tones In the cold months for some varieties, and there are cultivars with variegated (green-yellow) foliage. Leaf dimensions reach up to 7 cm long and 3 cm wide.
One of the main ornamental virtues of Duranta repens is its abundant floweringThe flowers, small but very showy, emerge grouped in long hanging clusters (up to 22 cm) or terminal spikes for much of the year, although especially from spring to autumn. The most common colors are blue, lilac and violet, although white flowers can also be found depending on the variety. Some species or hybrids display violet lines on two of their petals, further enhancing their aesthetic value.
After pollination, the flower clusters give way to drupe-shaped fruitsSmall, rounded, orange-yellow or deep orange, similar in size to a cherry. These fruits remain on the plant throughout the winter, adding additional ornamental interest. Each fruit typically contains two seeds.
Caution! Both the leaves and berries of the duranta contain compounds toxic, and are dangerous if ingested by children or pets. However, in some regions of Mexico, such as Hidalgo, cooked extracts of the leaves have been used for traditional medicinal purposes, although always under strict supervision and expert knowledge.

How do you care for Duranta repens?
The success in growing Duranta repens lies in offering it the conditions that favor its growth. growth and floweringBelow, we detail each relevant aspect for its optimal development:
- Location: He prefers the outdoors and a sunny exposure, which promotes spectacular flowering. It will grow well in semi-shade, but will flower less. It is advisable to place it in the shelter of strong winds and, in the case of harsh winters, protect young specimens with mulch, pine bark or straw to prevent frost damage.
- Climate: It adapts to temperate and warm climates, tolerating mild temperatures below zero, but it doesn't tolerate intense frosts or prolonged periods of extreme cold. In areas with moderate frost, it's best to protect the plant in a pot or protect its roots.
- Soil or substrate: It is not a demanding species, although requires a loose, well-drained substrate To prevent waterlogging and root rot. In clay soils, it is recommended to enrich the soil with silica sand or gravel. A specific substrate for outdoor plants, mixed with organic matter or peat and perlite, provides excellent results.
- Planting and transplanting: The best time to plant or transplant duranta is at the beginning of spring, when the plant enters vegetative growth. In a pot, choose a container slightly larger than the previous one and add a base of gravel to promote drainage.
- Irrigation: It is important to keep a regular watering regime, increasing the frequency in summer (3-4 times per week) and decreasing it in winter (2-3 times per week). Let the substrate dry slightly between waterings to avoid excess moisture. In pots, it's essential to ensure that water never accumulates at the bottom.
- Subscriber: To achieve vigorous growth and prolonged flowering, fertilize every 15 to 20 days from spring to late summer, alternating organic fertilizers (such as guano, mature compost or manure) with mineral fertilizers rich in phosphorous and potassium and a lower nitrogen intake (formulas such as 12-18-24 + trace elements). A slow-release fertilizer application in late winter will also be beneficial.
- Pruning: The duranta admits training pruning and maintenance, both to limit its size and to create hedges or topiaries. Ideally, prune it in late winter, removing dead or misshapen branches and thinning the center to allow light to enter. For mature specimens, wear gardening gloves to avoid injury from axillary thorns. Pinch regularly during spring and summer to maintain a more compact shape.
- Multiplication: It propagates easily by seed (pre-soaked for 4-5 days and sown in peat-rich substrate with vermiculite or perlite) or by semi-woody cuttings in spring and summer. The use of rooting hormones improves rooting success. Cuttings should be kept out of direct sunlight and in a well-ventilated environment for the first few weeks.
- Rusticity: It tolerates light frosts down to -2ºC, but in climates with harsher winters it is best to grow it in pots or protect the roots and base of the plant.
Common pests and diseases
One of the great advantages of Duranta repens is its high resistance to pests and diseases, although it's not completely immune. The main enemy is usually excess water, which can lead to fungal attacks and root rot. Among the pests that can occasionally affect it are:
- Aphids: They usually appear on tender shoots and can be eliminated with broad-spectrum insecticides or ecological solutions such as potassium soap.
- Mealybugs: They can colonize branches and leaves, so it is advisable to check the underside in spring and summer.
- Whitefly and mites: They appear in conditions of high heat and humidity; they require preventive treatments.
To prevent these problemsPreventive treatments are recommended in early spring with organic or broad-spectrum insecticides, and in cases of high humidity, fungicides are recommended to prevent the development of foliar or root fungi. Keeping the plant well-ventilated, free of excess moisture, is the best protection.

- Shrubby: specimens pinched several times to form globular, compact masses with a great visual effect.
- Variegated varieties: cultivars with yellowish-green leaves that add a touch of light to the garden.
- Bonsai: miniaturized version highly appreciated for its response to pruning and its branched structure.
