I. Sowing

For tiny seeds that are difficult to pick up with fingers or other tools, you can moisten one end of a toothpick with water and stick the seeds one by one onto the surface of the growing medium, then cover with 1 cm of medium. After that, place the sowing pot into water, with the water depth at 1/2 to 2/3 of the pot's height, and let the water slowly soak up from below (this method is called the "pot soaking method"). For larger seeds that can be picked up with fingers or other tools, place the seeds directly into the medium and sow them at a spacing of 3 x 5 cm. After sowing, cover with medium to a thickness of 2 to 3 times the size of the seeds. After sowing, use a sprayer or a fine-holed watering can to moisten the sowing medium. Later, when the potting soil is slightly dry, water again, but still be careful not to water too forcefully, so as not to wash the seeds out.

After sowing in late autumn, early spring, or winter, if cold waves and low temperatures occur, you can wrap the flower pot with plastic film to help keep it warm and moist. After the seedlings emerge, promptly uncover the film, and let the seedlings receive sunlight before 9:30 in the morning or after 3:30 in the afternoon each day; otherwise, the seedlings will grow very weak and spindly. After most of the seeds have sprouted, appropriate thinning is needed: pull out the diseased and unhealthy seedlings so that the remaining seedlings have some space between them. When most of the seedlings have grown 3 or more leaves, they can be transplanted.

II. Cuttings

Softwood cuttings are often taken from current-year branches in late spring and early autumn, or hardwood cuttings are taken from last year's branches in early spring.

1. Cutting medium

This refers to the nutrient soil, river sand, peat soil, and other materials used for cuttings. For home propagation, ideal cutting medium is hard to obtain due to limited conditions; medium-coarse river sand can also be used, but it should be rinsed several times with clean water before use. Do not use sea sand or river sand from saline-alkali areas; they are not suitable for the growth of flowering plants.

2. Cutting branches

When taking softwood cuttings, during late spring to early autumn when the plant is growing vigorously, select robust current-year branches as cuttings. After cutting the branches off, choose the sturdy parts and cut them into sections 5 to 15 cm long, each with more than 3 leaf nodes. When taking cuttings, note that the upper cut should be made straight across about 1 cm above the topmost leaf node, and the lower cut should be made at an angle about 0.5 cm below the lowest leaf node. Both the upper and lower cuts should be smooth (the knife should be sharp). When taking hardwood cuttings, after temperatures rise in early spring, select robust branches from the previous year as cuttings. Each cutting usually retains 3 to 4 nodes, and the cutting method is the same as for softwood cuttings.

III. Layering propagation

Select a robust branch, and about 15 to 30 cm below the tip, remove a ring of bark. The width of the wound after peeling should be about 1 cm, and the depth should be just enough to remove the outer bark. Cut a piece of plastic film 10 to 20 cm long and 5 to 8 cm wide, place some moistened garden soil on it, and wrap the girdled part as if bandaging a wound. Tie the top and bottom ends of the film tightly, so the middle bulges out. Roots will form after about four to six weeks. After rooting, cut off the branch together with the roots, and it becomes a new plant.

Mucuna birdwoodiana is a vine in the Fabaceae (Papilionaceae) family and also a second-class protected plant in China. Its flower shape closely resembles a sparrow, hanging in clusters like sparrows dancing, hence the name. Below, let us learn about related knowledge of Mucuna birdwoodiana and see how it propagates and how to grow it.

Introduction to Mucuna birdwoodiana

Mucuna birdwoodiana is a vine in the Fabaceae (Papilionaceae) family and a second-class protected plant in China. It usually includes several types, such as Mucuna birdwoodiana with white flowers, Mucuna birdwoodiana with beautiful leaves and purple flowers, and evergreen Mucuna birdwoodiana with deep purple flowers. It is a woody vine in the genus Mucuna of the Fabaceae (Papilionaceae) family. The clustered raceme inflorescences grow directly on the vines, and it is named because its shape resembles a sparrow. It is native to tropical and subtropical Asia, and is cultivated in southern China.

Mucuna birdwoodiana has clustered raceme inflorescences that grow directly on the vines. Its flower shape closely resembles a sparrow, hanging in clusters like sparrows dancing. The flowers have five petals, white or pale green, and bloom from March to late April each year. It is mainly distributed in tropical and subtropical Asia, and the Wuyi region of Guangdong, China, is very famous for it. It is mainly distributed in tropical and subtropical Asia, and the Wuyi region of Guangdong, China, is very famous for it.

It has alternate trifoliate compound leaves; new leaves are tender green, old leaves grayish green. Young branches are brown or green, soft and slender. The bark of old branches is cracked, with reddish-brown longitudinal stripes in between; after the reddish-brown stripes fall off, black dot-like transverse stripes remain. Mucuna birdwoodiana has a very strong climbing ability and can coil around large trees like a giant python. Clustered raceme inflorescences grow directly on the vines. Its flower shape closely resembles a sparrow, hanging in clusters like sparrows dancing. The flowers have five petals, mostly white, but also pink, purple, and even purplish black; each flower looks like a little bird. The flowers bloom on the vines, hanging in clusters, with each cluster ranging from twenty to thirty flowers or more, drooping in strings, like thousands of birds perched on branches, with both form and spirit, amazing to behold. It blooms from March to late April each year. The petals are pale green, and two petals curl into wing-like shapes. Wind makes Mucuna birdwoodiana charming in countless ways and very captivating, with considerable ornamental value. It is mainly distributed in tropical and subtropical Asia, and Qingxi Town in Guangdong Province, China, in the Wuyi region of Guangdong, is very famous for it.

Mucuna birdwoodiana flowers are about 5 to 8 cm long, and each flower looks like a little bird. There are five petals in total, and the petal colors are varied, including pale green, purple, brown, creamy white, and so on. Mucuna birdwoodiana blooms around Qingming Festival each year, with clustered raceme inflorescences growing directly on the vines. Its flower shape closely resembles a sparrow, hanging in clusters like sparrows dancing. Two petals curl into wing-like shapes, the receptacle resembles a sparrow's head, with a small black dot on each side like an eye; the central petal curves like a sparrow's back, the petals on both sides resemble sparrow wings, and the lower petal extends backward like a tail.

I. Morphological characteristics

Mucuna birdwoodiana has clustered raceme inflorescences that grow directly on the vines, and it is named because its shape resembles a sparrow. It is native to tropical and subtropical Asia, and is cultivated in southern China. Mucuna birdwoodiana has five petals, mostly white, but also pink, purple, and even purplish black. When the flowers are in full bloom, they look like little birds spreading their wings to fly. After white Mucuna birdwoodiana flowers are picked, they turn brown within two or three hours, looking even more like sparrows. If the petals are accidentally damaged, a red sap like blood flows out, which is considered remarkable by people and has made it famous in China and abroad. The flowering period of Mucuna birdwoodiana is relatively short, generally blooming from March to late April each year, with a flowering period of about 40 days. Because Mucuna birdwoodiana is evergreen year-round and blooms profusely, it has considerable ornamental value.

II. Ecological habits

Mucuna birdwoodiana likes humid or semi-dry climate environments and requires the relative air temperature of the growing environment to be 50 to 70%. When the relative air humidity is too low, the lower leaves turn yellow and fall off, and the upper leaves lose their luster. Because Mucuna birdwoodiana is native to subtropical regions, it has strict requirements for winter temperatures and stops growing when the ambient temperature is below 8°C.

In the flowering season, Mucuna birdwoodiana hangs in clusters, growing directly on the vines, with each cluster containing twenty to thirty flowers, connected by a small green vine. When in full bloom, the old vines and old trees are covered with Mucuna birdwoodiana flowers, closely resembling thousands of sparrows resting under the dense shade of the forest, a magnificent sight.

Looking at Mucuna birdwoodiana from a distance, you might think it really is a flock of sparrows hiding among the flowering vines. If white Mucuna birdwoodiana flowers are picked, they turn brown after two or three hours, looking even more like sparrows. If the petals are accidentally damaged, red sap flows out, just like blood, making it seem even more magical. Mucuna birdwoodiana generally blooms around Qingming, with a flowering period of about 40 days. Mucuna birdwoodiana generally only blooms and does not bear fruit.

Mucuna birdwoodiana prefers light. It blooms abundantly in sunny sites, and also blooms heavily in semi-shaded sites, but dislikes deep shade. It prefers fertile, moist soil and is suitable for growing in deep sandy loam.

How Mucuna birdwoodiana propagates

Mucuna birdwoodiana can be propagated and raised from seed by cuttings and layering. Cuttings are taken before spring sprouting; select robust branches as cuttings, soak the lower ends in a rooting hormone solution such as rooting powder, then insert them into a wet sand bed with shade and misting to maintain humidity, and they root in about 1 month. For outdoor cuttings in summer, a shade shed is needed to block light. Layering mainly uses vines that have fallen to the ground; after scoring the lower part of a node, press it into the soil and keep it moist. After rooting, cut off the new plant. When used for ground planting or vertical greening, pond mud mixed with peat soil or aged manure such as garbage soil can be used as a slow-release fertilizer, and plant growth should be properly controlled. It has strong sprouting ability, and for pruning, after autumn begins, dense vines and aging branches should be pruned and cleaned once to increase light penetration and promote flower bud formation.

(1) Sowing propagation

Seed selection: Before sowing, the seeds must first be selected. Whether the seeds are well chosen directly affects whether sowing will succeed.

1. It is best to use seeds harvested in the current year. The longer the seeds are stored, the lower their germination rate.

2. Choose seeds that are plump and free of defects or deformities.

3. Choose seeds free of pests and diseases.

Disinfection: Disinfection includes two concepts: one refers to disinfecting the seeds, and the other refers to disinfecting the sowing medium.

For home seed disinfection, it is common to soak the seeds in hot water at about 60°C for a quarter of an hour, then use warm water to promote germination for 12 to 24 hours.

To disinfect the sowing medium, the best method is to heat it in a pot until hot; any pests and diseases will be killed by the heat.

Germination promotion: Soak the seeds in warm water (temperature similar to face-washing water) for 12 to 24 hours, until the seeds absorb water and swell. For very common seeds that germinate easily, this step can be skipped.

Sowing: For tiny seeds that are difficult to pick up with fingers or other tools, you can moisten one end of a toothpick with water and stick the seeds one by one onto the surface of the medium, then cover with 1 cm of medium. After that, place the sowing pot into water, with the water depth at 1/2 to 2/3 of the pot's height, and let the water slowly soak up from below (this method is called the “pot soaking method”);

After sowing, cover with medium to a thickness of 2 to 3 times the size of the seeds. After sowing, use a sprayer or a fine-holed watering can to moisten the sowing medium. Later, when the potting soil is slightly dry, water again, but still be careful not to water too forcefully, so as not to wash the seeds out;

Management after sowing: After sowing in late autumn, early spring, or winter, if cold waves and low temperatures occur, you can wrap the flower pot with plastic film to help keep it warm and moist; after the seedlings emerge, promptly uncover the film, and let the seedlings receive sunlight before 9:30 in the morning or after 3:30 in the afternoon each day; otherwise, the seedlings will grow very weak and spindly; after most of the seeds have sprouted, appropriate thinning is needed: pull out the diseased and unhealthy seedlings so that the remaining seedlings have some space between them; when most of the seedlings have grown 3 or more leaves, they can be transplanted.

It has strong sprouting ability, and for pruning, after autumn begins, dense vines and aging branches should be pruned and cleaned once to increase light penetration and promote flower bud formation.

1. Temperature: The optimum temperature for cutting rooting is 20°C to 30°C. Below 20°C, cuttings root with difficulty and slowly; above 30°C, the upper and lower cuts of the cuttings are easily infected by pathogens and rot, and the higher the temperature, the greater the proportion of rot. When low temperatures occur after cutting, the main measure for keeping warm is to wrap the flower pot or container used for cuttings with film; when the temperature is too high after cutting, the main cooling measure is to shade the cuttings, blocking 50 to 80% of sunlight, and at the same time mist the cuttings 3 to 5 times a day. On sunny days with higher temperatures, mist more often; on cloudy and rainy days with lower temperatures and higher humidity, mist less often or not at all.

2. Humidity: After cutting, the relative air humidity must be maintained at 75 to 85%. The basic requirement for cutting rooting is that before the cuttings root, they must be kept fresh and tender so they can carry out photosynthesis to produce rooting substances. However, cuttings that have not rooted cannot absorb enough water to maintain their internal water balance. Therefore, misting must be used to reduce water evaporation from the cuttings: under shaded conditions, mist the cuttings 3 to 5 times a day. On sunny days, the higher the temperature, the more frequent the misting; on cloudy and rainy days, the lower the temperature, the less frequent the misting or no misting. But excessive misting makes cuttings prone to infection by pathogens and rot, because many kinds of pathogens exist in water.

3. Light: Cutting propagation cannot be separated from sunlight, because the cuttings still need to continue photosynthesis to produce nutrients and rooting substances to supply their rooting needs. However, the stronger the light, the higher the temperature inside the cuttings, the more active the transpiration of the cuttings, and the more water they consume, which is not conducive to the survival of the cuttings. Therefore, after cutting, 50 to 80% of sunlight must be blocked. After the root system grows out, gradually remove the shade net: on sunny days, remove the shade net at 4:00 pm each day, and cover it again before 9:00 am the next day.

How to grow Mucuna birdwoodiana

1. Humidity management

Mucuna birdwoodiana likes humid or semi-dry climate environments and requires the relative air temperature of the growing environment to be 50 to 70%. When the relative air humidity is too low, the lower leaves turn yellow and fall off, and the upper leaves lose their luster.

2. Temperature management

Because Mucuna birdwoodiana is native to subtropical regions, it has strict requirements for winter temperatures and stops growing when the ambient temperature is below 8°C.

3. Light management

Mucuna birdwoodiana has a strong ability to adapt to light. When kept indoors, place it in a place with bright light as much as possible, such as a well-lit living room, bedroom, study, and similar locations. After being kept indoors for a period (about one month), move it outdoors to a shaded place (with winter warmth protection conditions) for a period (about one month), and alternate this way.

4. Potting and transplanting

When potting small Mucuna birdwoodiana seedlings or repotting large plants that have been grown for several years, first place a 2 to 3 cm thick layer of coarse-grained medium at the bottom of the pot as a drainage layer, sprinkle a layer of fully decomposed organic fertilizer on top as base fertilizer, about 1 to 2 cm thick, then cover with a thin layer of medium about 1 to 2 cm thick, and then place the plant in, so as to separate the fertilizer from the root system and avoid burning the roots. The medium used for potting can be selected from one of the following: After potting, water once thoroughly, and place it in a shaded environment for one week of care. When transplanting seedlings, first dig the planting hole, sprinkle a layer of organic fertilizer at the bottom of the planting hole as base fertilizer, about 4 to 6 cm thick, then cover with a layer of soil and place the seedling in, so as to separate the fertilizer from the root system and avoid burning the roots. After placing the seedling in, backfill the soil, cover the root system, and press the soil firm with your feet, then water once thoroughly.

5. Fertilizer and water management

For potted Mucuna birdwoodiana plants, in addition to adding organic fertilizer when potting, appropriate fertilizer and water management is also needed during regular care.

Spring, summer, and autumn: These three seasons are its peak growth periods. Fertilizer and water management follows the cycle of “Hua Bao”——clear water——“Hua Bao”——clear water, with an interval of about 1 to 4 days,

Winter: During the winter dormancy period, the main task is to control fertilizer and water well. Fertilizer and water management follows the cycle of “Hua Bao”——clear water——clear water——“Hua Bao”——clear water——clear water, with an interval of about 3 to 7 days. On sunny days or during high temperatures, the interval is shorter; on cloudy and rainy days or during low temperatures, the interval is longer or no watering is done. For ground-planted plants, in spring and summer, according to drought conditions, apply fertilizer and water 2 to 4 times: first open a small trench in a ring 30 to 100 cm away from the root crown (the larger the plant, the farther from the root crown), with the trench width and depth both 20 cm. Spread 25 to 50 jin of organic fertilizer into the trench, or 1 to 5 liang of granular compound fertilizer (chemical fertilizer), then water thoroughly. After winter begins and before spring begins, apply fertilizer once more in the same way as above, but do not water.

6. Pruning potted plants

In winter, when Mucuna birdwoodiana enters dormancy or semi-dormancy, cut off weak, pest-damaged, dead, and overly dense branches. Branches can also be organized in combination with cuttings.

7. Repotting

As long as Mucuna birdwoodiana is cared for properly, it will grow very quickly. When it grows to a certain size, consider giving it a larger pot so it can continue to grow vigorously. The growing soil and component ratios used for repotting can be selected from one of the following: vegetable garden soil: cinder = 3:1; or garden soil: medium-coarse river sand: sawdust (mushroom residue) = 4:1:2; or one of paddy soil, pond mud, or leaf mold.

8. Removing from the pot

For Mucuna birdwoodiana to be repotted, place the flower on the ground, first lightly pat around the pot with the palm of your hand to loosen the root system from the pot wall, then turn the flower pot upside down on your left hand, gently hold the plant between your left index finger and middle finger, brace your wrist and fingertips against the pot rim, pat the bottom of the pot with your right hand, and use your thumb to push the root soil downward through the bottom hole, letting the plant come out. After it comes out, gently pat the potting soil with both palms to let excess soil fall off.

9. Preparing the flower pot

Choose a flower pot of appropriate size. Cover the bottom hole of the pot with two pieces of tile or thin foam pieces, ensuring both that the potting soil is not washed out by water and that excess water can drain out in time. On top of the tile or foam, place a layer of expanded clay pellets or crushed red bricks as a drainage layer, about 2 to 3 cm thick. On the drainage layer, place organic fertilizer, about 1 to 3 cm thick. On the fertilizer, place a thin layer of medium, about 2 cm thick, to separate the root system from the fertilizer. Finally, place the plant in, fill with nutrient soil, and leave about 2 to 3 cm from the pot rim.

Mucuna birdwoodiana is distributed in Jiangmen, Zhaoqing, Guangzhou, Qingyuan, Shaoguan, and other places in Guangdong, but is more abundant in Jiangmen.
