Clerodendrum thomsonae is a shrub in the Verbenaceae family. Its young branches are four-angled and covered in short yellow-brown hairs, which disappear as the plant matures.
The leaves are papery, narrow-ovate or ovate-lanceolate in shape, with a gradually pointed tip and a rounded base.
They have a smooth margin and are arranged in an umbrella-like inflorescence, which can be axillary or pseudoterminal. The bracts are lanceolate in shape. The calyx is white, with a fused base and an enlarged middle section.
The lobes of the calyx are triangular-ovate in shape, with a pointed tip. The corolla is deep red and covered in fine glandular hairs, with elliptical lobes. There are four stamens, which protrude from the corolla along with the style.
The stigma is shallowly divided into two lobes. The fruit is nearly spherical, with a shiny brown-black outer skin. The persistent calyx does not enlarge and is reddish-purple in color. The flowering period is from March to May.
Dragon’s Blood prefers a warm, moist, and sunny semi-shaded environment and is not tolerant of cold temperatures. It is native to West Africa, Mexico, and is cultivated in China.
Dragon’s Blood is a climbing shrub that can reach a height of 2-5 meters. Its young branches are four-angled and covered in short yellow-brown hairs, which disappear as the plant matures. The pith of the small branches is loose when young but becomes hollow in old age.
The leaves are papery, narrow-ovate or ovate-lanceolate in shape, measuring 4-10 cm in length and 1.5-4 cm in width. They have a gradually pointed tip, a nearly rounded base, and a smooth margin.
The upper surface is covered in small warts, giving it a slightly rough texture, while the lower surface is nearly hairless. The leaf veins are three-branched. The petiole is 1-2 cm long.
The umbrella-like inflorescence is axillary or pseudoterminal, with dichotomous branching. It measures 7-15 cm in length and 10-17 cm in width. The bracts are lanceolate in shape, measuring 0.5-1 cm in length.
The calyx is white, with a fused base and an enlarged middle section. It has five ridges and five deeply divided lobes at the top.
The calyx is covered in fine hairs, and the lobes are triangular-ovate in shape, measuring 1.5-2 cm in length and 1-1.2 cm in width, with a pointed tip.
The corolla is deep red and covered in fine glandular hairs. The lobes of the corolla are elliptical in shape and measure approximately 9 mm in length.
The corolla tube is nearly equal in length to the calyx. There are four stamens, which protrude from the corolla along with the style. The stigma is shallowly divided into two lobes.
The fruit is nearly spherical, with a diameter of approximately 1.4 cm. It contains 2-4 seeds. The outer skin of the fruit is shiny and brown-black. The persistent calyx does not enlarge and is reddish-purple in color. The flowering period is from March to May.
Dragon’s Blood prefers a warm, moist, and sunny semi-shaded environment and is not tolerant of cold temperatures.
The optimal temperature for growth is between 18-30°C from February to October, and 13-16°C from October to the following February.
During winter, the temperature should not drop below 8°C, as temperatures below 5°C can cause damage to the stems and leaves, resulting in leaf drop or wilting of tender stems.
During the period of vegetative growth, higher temperatures above 30°C can be tolerated as long as there is sufficient water supply. However, for reproductive growth, particularly during the flowering period, lower temperatures around 17°C are more suitable.
Dragon’s Blood is native to West Africa, Mexico, and is cultivated in greenhouses throughout China.
Cuttings are usually taken from healthy and disease-free branches in May to June. The apical shoots of young branches can be selected, or the lower part of older branches can be cut into 8-10 cm stem segments for use as cuttings.
Bud grafting involves taking side shoots from branches, including a portion of the woody tissue, as the scion. Rhizome cuttings can be made by cutting the creeping rhizome into 8-10 cm long segments.
The cuttings can be planted in a mixture of peat, perlite, leaf mold, river sand, and vermiculite as the rooting medium.
Spring and autumn are the best seasons for cuttings, with an optimal temperature of 21°C for rooting and 26°C for the propagation bed, which greatly promotes root formation.
Roots can develop within 3 weeks. Treating the basal part of the cuttings with a 0.5%-0.8% indolebutyric acid solution for 1-2 seconds can accelerate and increase the rooting process.
The seeds have a short lifespan and should be sown immediately after harvesting. They can be sown in shallow trays in March to April, with a temperature maintained at 24°C.
Germination can occur within 10 days. When the seedlings reach a height of ten centimeters, they can be transplanted into pots. The plants may start flowering in the second year.
However, the success rate of seed propagation is low, so it is recommended to use the cutting method for propagation.
Dragon’s Blood, belonging to the Verbenaceae family, is susceptible to leaf spot disease caused by fungal infections.
Initially, small brown spots appear, which can develop into large black spots if not treated in a timely manner, leading to yellowing and death of the leaves.
Therefore, it is important to immediately use a 800-fold diluted solution of a fungicide like Bacillus subtilis for foliar spraying every 7-8 days, repeated 2-3 times, to effectively control the disease.
Common pests include scale insects and whiteflies, which can be controlled by spraying with a 40% diazinon solution diluted to 1000-1500 times.
If the leaves cannot fully expand and turn yellow due to alkaline soil, irrigating with a 0.2% ferrous sulfate solution can help resolve the issue.
For leaf and fungal diseases, it is important to promptly remove fallen diseased leaves, improve ventilation, and keep the leaves dry to control the spread of the disease.
Functions: Treats boils, abscesses, swelling, bruises, clears heat, detoxifies, disperses blood stasis, and reduces swelling.

This species is a beautiful ornamental plant. During flowering, the deep red corolla extends from the white calyx, resembling a string of pearls. The flowers are unique in shape and bloom profusely.
The flowers consist of bracts that form a pyramidal calyx, resembling milky white “starfruit.” Between the clefts at the tip, five deep red flowers emerge, evenly distributed on the leaves, resembling red beads that continuously emerge.
Generally, potted plants remain short due to pruning. It is mainly used for greenhouse cultivation as an ornamental plant and can be used as a trellis or as a decoration for windowsills and small summer gardens.
It can also be used in parks or tourist sites to create flower baskets, arches, pavilions, and various patterns, adding elegance for visitors.
