Malan head, also known as Malan, red stalks, chicken intestine, field side chrysanthemum, purple chrysanthemum, crape myrtle, etc., belongs to the daisy family Malan genus perennial herbaceous plants. Malan head is originally a wild species, born on roadsides, fields, slopes, most parts of the country are distributed. The following is what I have organized for you, welcome to refer to the time of flowering of `Malantou

Flowering period of Malantou:

May-September

Morphological features

The rhizome of Malantou is creeping, sometimes with a taproot, and sometimes with a taproot. Sometimes with taproot. Stem erect, 30-70 cm tall, shortly hairy distally, branched distally or from below.

Basal leaves withered at anthesis; stem leaves oblanceolate or obovate-matrix-rounded, 3-6 to 10 centimeters long, 0.8-2 to 5 centimeters wide, apex obtuse or pointed, base attenuate into winged long-stalked, margins obtuse or cuspidate-toothed or pinnately lobed with small cusps from the middle upward, distal leaves small, entire, base sharply narrowed and sessile, all leaves slightly thinly textured, sparsely puberulent or subglabrous on both surfaces or above, margins and along veins below with short hairs.

The capitula are borne singly at the ends of the branches and arranged in sparse corymbs. Involucre hemispherical, 6-9 mm in diameter, 4-5 mm long; involucral bracts 2-3-layered, imbricate; outer oblanceolate, 2 mm long, inner oblanceolate-rectangular, up to 4 mm long, tip obtuse or slightly pointed, herbaceous distally, sparsely short hairy, margin membranous, ciliate. Receptacle conic. Ligule 1-layered, 15-20, tube 1.5-1.7 mm long; ligule light purple, up to 10 mm long, 1.5-2 mm wide; tube 3.5 mm long, tube 1.5 mm long, covered with short dense hairs.

Achenes obovate-square, extremely compressed, 1.5-2 mm long, 1 mm wide, brown, margins pale and thickly ribbed, glandular and pubescent distally. Crown hairs 0.1-0.8 mm long, weak and easily deciduous, unequal. Flowering May-September, fruiting August-November. [1]

Growing environment

Malan head widely adaptable, preferring temperature is also more tolerant of shade, resistance to cold and heat is very strong, light requirements are not strict, in 32 ℃ high temperatures can be normal growth in -10 ℃ can be safe below the over-wintering, when the local temperature rebounded to 10-12 ℃, the temperature in 10-15 ℃, the young leaves and young stems will begin to grow rapidly. The young leaves and stems start to grow rapidly when the temperature rises to 10-12℃ and the temperature is 10-15℃. Seed germination temperature at about 20 ℃, young leaves and young stems of the harvest period is mainly concentrated in March to April.

Distribution

Extremely common throughout China, widely distributed in the Yangtze River basin. It is more common in Jiangsu and Zhejiang. Born on mountain slopes, field margins and roadsides, it is distributed throughout the country. Widely distributed in southern and eastern Asia. [1] ? In the United States, marjoram grows only in the state of Hawaii.
