The genus Clerodendrum belongs to the Verbena family. Representatives of the genus are distributed mainly in tropical Asia and Africa, partly in South America. The old name volcameria was once common to all cultivated clerodendrum, but is practically not used today. The name of the genus is formed by the fusion of the Greek words kleros and dendrum, and when translated into Russian it sounds like “tree of fate” or “tree of happiness”.
In our photo gallery below are photos of various types of clerodendrum – both widely cultivated and rare, requiring special growing conditions.
The most popular species is the most beautiful clerodendrum (Clerodendrum speciosissimum), a tall shrub with tetrahedral shoots. Clerodendrum flowers are collected in apical panicles; calyx purple; corolla garnet red.
Clerodendrum brilliant (Clerodendrum splendens) – shrub with round shoots, often curly. The flowers of the clerodendrum of this species are scarlet-red, collected in apical and axillary shields or in short brushes. Blooms profusely throughout most of the year.
Clerodendrum fragrant (Clerodendrum fragrans) has white, pinkish flowers on the outside with a strong pleasant aroma, densely collected in apical shields up to 8 cm in diameter. Blooms (intermittently) throughout the year.
Wallich’s Clerodendrum (Clerodendrum wallichiana) is distinguished by very beautiful glossy lanceolate dark green leaves up to 15 cm long, wavy along the edge. From the end of August, the shoots are crowned with lush hanging inflorescences with sequentially (within 1.5-2 months) blooming buds. Flowers up to 3 cm in diameter have five oval petals and long, far protruding stamens and pistil.
Ugandan Clerodendrum (Clerodendrum ugandense) due to the shape of the flowers was called “Blue Butterflies”. Flowers (blue or purple, one part of the perianth lilac-violet) are collected in a loose, few-flowered inflorescence. Stamens are long, curving, blue. Flowers are formed at the ends of the shoots, so pruning is carried out after flowering.
Ms. Thomson’s clerodendrum, or Thomson’s clerodendrum (Clerodendrum thomsoniae), is relatively unpretentious, it is most often grown in rooms. The flowers have a scarlet-red corolla with a cylindrical tube and a white-pink calyx. It blooms from March to September, and in warm rooms almost throughout the year.
Clerodendrum houseplant care at home
Indoor plant klerodendrum prefers a bright, shaded from direct sun, warm place. The plant is sensitive to soil composition, water quality and needs regular feeding. In winter, it is kept at a temperature of 12-14 ° C and watering is significantly reduced. In the spring, the plant is cut, transplanted, watered more and transferred to a warm place.
When caring for clerodendrum at home, the plant must be sprayed daily, especially in well-heated rooms. For spraying and watering use only soft water at room temperature. Watered so that the earthen ball was only slightly damp. Feed from March to August every week with complex mineral and organic fertilizers, alternating them. In the spring, old shoots are pruned. Clerodendrums actively bloom young shoots 12-15 cm long, so it is necessary to stimulate their formation by pinching or pruning branches.
Clerodendrum is transplanted only when the pot becomes cramped. The soil mixture should be loose, moisture-intensive, with a slightly acidic reaction (pH 6-6.5). It is prepared from peat, leaf earth and sand, taken in equal quantities.
Propagated by seeds and woody cuttings. In May, the tops of the shoots are cut off. Cuttings easily give roots in water, and then they are planted in a loose nutrient substrate and kept at a temperature of about 25 ° C. The cuttings must be covered with a transparent cap for two weeks, periodically removing it for a short while to ventilate the plants.
Whiteflies, spider mites, scale insects harm a houseplant. In case of violation of the conditions of detention, flowers and leaves fall.
