Haemanthus albiflos is also known as tiger ear, snake plant, ox tongue plant, etc. It is native to southern Africa and is a perennial evergreen herbaceous plant of the genus Haemanthus in the Amaryllidaceae family. Its leaves remain evergreen all year round and its form is elegant. When it blooms, the tips of the white flower clusters bear yellow anthers, which are bright and eye-catching. It is suitable for indoor potted appreciation.

Growth habits of Haemanthus albiflos

Haemanthus albiflos is native to tropical Africa and has been introduced and cultivated in China. It likes a sunny, warm, humid, and well-ventilated environment. It is relatively drought-tolerant but not cold-tolerant. The suitable growth temperature is 15-25°C, and it requires well-drained slightly acidic loam. The cultivation substrate can be made by mixing peat, leaf mold, and river sand evenly. During the growing season, apply decomposed cake fertilizer once a month, and appropriately supplement with phosphorus fertilizer. After winter dormancy, it can be repotted and divided. In cold regions, it should be moved into a greenhouse for maintenance, ensuring a minimum temperature of 5°C, otherwise it is prone to freezing damage.

Propagation methods of Haemanthus albiflos

1. Seed propagation: The seeds of Haemanthus albiflos mature more than 2 months after flowering and can be sown directly in pots. They germinate 15 days after sowing, and seedlings need 4 to 5 years to bloom.

2. Division propagation: The small bulbs of Haemanthus albiflos develop slowly, generally dividing once every 2 to 3 years. When repotting in spring, lift out the mother plant and separate and replant the offsets.

Cultivation methods of Haemanthus albiflos

1. Soil: Haemanthus albiflos is suitable for growing in loose, fertile, well-drained slightly acidic sandy loam. A mixture of peat, leaf mold, and river sand can be chosen and mixed evenly. During the growing period, fertilize once every ten days.

2. Watering: For Haemanthus albiflos, water only after the surface soil dries. Never let it be exposed to rain or allow waterlogging, as this will cause bulb rot. If the potting soil is too dry in summer and autumn, it will affect leaf growth. In winter it has a short semi-dormant state, so watering should be reduced.

3. Light: Haemanthus albiflos needs a relatively good light environment. In summer it should be shaded, and in other seasons light should be strengthened. Excessive shade will not only make the leaves thinner, but also affect flowering and the overall plant form.

4. Temperature: The suitable growth temperature for Haemanthus albiflos is 10-12°C at night and 16-21°C during the day. In summer it should be kept in semi-shade, and during the flowering period it needs cool conditions. In late autumn the bulbs go dormant for the winter, and the temperature must not be lower than 5°C, while keeping the soil dry.

Precautions for Haemanthus albiflos

1. Special attention should be paid to Haemanthus albiflos during the rainy season. It must not be exposed to rain, and the potting soil must not be allowed to become waterlogged. It is best to place it in a sheltered spot away from rain.

2. Normally, apply a 15% cake fertilizer solution once every half month to Haemanthus albiflos, and before flowering, apply compound fertilizer twice additionally.

3. If Haemanthus albiflos receives insufficient light or the potting soil is too wet, it will cause excessive growth of branches and leaves, leading to soft, drooping leaves and reduced ornamental value.

4. Haemanthus albiflos is not very cold-tolerant. It should be moved indoors in early winter and placed in a sunny spot. As long as the temperature is not lower than 0°C, it can overwinter.

The fleshy leaves are thick, evergreen, entire-margined, with tongue-shaped tips and fine fuzz, closely resembling tiger ears, hence the name tiger ear plant.

1. Introduction

[Scientific name] Haemanthus albiflos jacq.
[Classification] Amaryllidaceae, Haemanthus
[Distinction] Haemanthus albiflos belongs to the Liliaceae (or is classified under Agavaceae), while snake plant belongs to the genus Sansevieria. It is also sometimes mistakenly called "tiger ear plant," which should be regarded as a misnomer and must not be confused with this species. The two are completely different in morphology and habits.
Haemanthus albiflos is also known as ox tongue plant and is a perennial evergreen herbaceous plant of the Amaryllidaceae family. Its leaves are broad and thick, fleshy, emerging from the short stem above the bulb. The umbel is terminal, and the flowers may be white, red, or pink, with white-flowered ones being the most common. Haemanthus albiflos is a perennial evergreen herbaceous plant of the genus Haemanthus in the Amaryllidaceae family, native to southern Africa. The broad-leaved form has a plant height of 20-30 cm. The rhizome is shortened or flattened spherical and has nodes. The leaves emerge from the base, are opposite, spreading, wide and large, usually 4-6 in neat arrangement.

2. Growth habits

Haemanthus albiflos likes a sunny, warm, humid, and well-ventilated environment. It is relatively drought-tolerant but not cold-tolerant. The suitable growth temperature is 15-25°C, and it requires well-drained slightly acidic loam.
The substrate for cultivating Haemanthus albiflos can be made by mixing peat, leaf mold, and river sand evenly. During the growing season, apply decomposed cake fertilizer once a month, and appropriately supplement with phosphorus fertilizer. After winter dormancy, it can be repotted and divided. In cold regions, it should be moved into a greenhouse for maintenance, ensuring a minimum temperature of 5°C, otherwise it is prone to freezing damage. Haemanthus albiflos is an excellent foliage flower. Its leaves are broad and slightly curved, with an elegant posture. It produces terminal inflorescences every year in August. When potted and displayed on stands, desks, bookcases, and other places, it is lush and pleasant, with a very good ornamental effect.
Propagation
Seeding and division are commonly used. For seed propagation, the seeds mature more than 2 months after flowering. Because the seeds are large, they can be sown directly in pots. They germinate 15 days after sowing, and seedlings need 4-5 years of growth to bloom. For division propagation, the small bulbs develop slowly, generally dividing once every 2-3 years. Usually in March to April when repotting, lift out the mother plant, separate the small bulbs and replant them. It takes 2 years of cultivation to bloom.

5. Biological characteristics

Tissue culture is often used in flower and nursery stock production because it has advantages such as a high propagation coefficient, speed, and the ability to obtain virus-free plants. Haemanthus albiflos is a bulbous plant of the genus Haemanthus in the Amaryllidaceae family, also known as white-flowered Haemanthus, white-flowered Haemanthus multiflorus, and white-flowered paintbrush flower. It is native to southern Africa. Haemanthus albiflos can be enjoyed both for its flowers and leaves. In the Shanghai area it blooms in early winter, and the flowering period can last as long as 2 months. Its flowers and leaves are delicate, beautiful, and elegant, and the plant remains evergreen year-round, making it very suitable for indoor potted appreciation. It is commonly propagated by division or seeding, but in the Shanghai area it cannot produce seeds, and propagation is very slow. To provide a new possible route for rapid propagation, explants were selected from young leaves sprouted in spring from vigorous potted Haemanthus albiflos plants, rinsed clean with tap water, then on a clean bench rinsed with 75% alcohol for 30, rinsed twice with sterile water, then shaken and washed in saturated bleaching powder solution for 20, finally rinsed 3-4 times with sterile water and blotted dry with sterile filter paper. The leaves were cut into 0.5 explant pieces and inoculated into induction media containing +0.65% agar +3% sucrose + different 6- and concentration combinations. Forty pieces were inoculated per treatment, repeated 3 times. The 6- and combinations were as follows: -1: 6-0.5/(same units below)+0.2; -2: 6-0.5+1.0; -3: 6-0.5+2.0; -4: 6-1.0+1.0; -5: 6-2.0+1.0; -6: 6-3.0+1.0; -7: 6-2.0+0.1; 1-8: 6-3.0+0.1. 1.3 Strong shoot proliferation: Cut the explant pieces with adventitious buds into small pieces and inoculate them onto media containing +0.65% agar +3% sucrose + different 6- and concentration combinations + different concentrations. Twenty pieces were inoculated per medium, repeated 3 times. The 6- and ratio and concentration combinations were as follows: -1: 6-2.0+0.; -2: 6-2.0+0.1+0.2%; -3: 6-0.5+2.0.

The proliferation multiple of adventitious buds was counted (proliferation multiple = total number of buds/number of inoculated buds), and the growth of adventitious buds was observed. 1.4 Rooting: Under sterile conditions, take rootless test-tube plantlets obtained from the -2 medium with basically consistent growth and 2.5 or more, and inoculate them into 1/2 +0.65% agar +1.5% sucrose + different concentrations of or + different concentrations of medium. Sixty-six plantlets were inoculated per medium, repeated 3 times. After 20 of culture, the rooting rate of test-tube plantlets in each medium was counted. After 40, root growth indices were measured (root number, root length, root-to-shoot ratio). The concentration and concentration combinations were as follows: -1: 0.2; -2: 0.2+0.2%; -3: 0.2; -4: 0.2+0.2%. 1.5 Transplanting: After the seedlings grow vigorous roots, open the bottles at room temperature to harden the seedlings for 21, then directly transplant them into pots with 1/3 peat +2/3 sandy loam; or after hardening at room temperature for 2, first transplant into a substrate of (peat):(perlite):(vermiculite)=4:2:1, water with 0.1% solution (add a few drops), and after one week transplant into pots with 1/3 peat +2/3 sandy loam.
The above medium pH was adjusted to about 5.8; culture temperature 25±2, light intensity 1500-2000, daily light 12. 1.1.2 Results and analysis 2.1 Induction of adventitious buds: Explant pieces were inoculated onto -1, -2, -3, -4, -5, -6, -7, and -8 media. After about 15, all explants showed obvious thickening and swelling. After continuing culture for 7, a small amount of callus appeared at the cut edges of the explants. After continuing culture for another 7, adventitious buds formed on the explants on -7 and -8 media. The small amount of callus that appeared on -1, -2, -3, -4, -5, and -6 media continued to grow, forming obviously enlarged callus masses around the explants. After continuing culture for another 30, the callus masses on -1, -2, and -3 media differentiated a small number of adventitious buds, while the callus masses on -4, -5, and -6 media continued to grow, and if cultured further gradually browned, with very few able to differentiate adventitious buds, and some even showed adventitious root differentiation. The adventitious bud induction rate of explants on the above media was counted [adventitious bud induction rate = number of explants with buds/(number of inoculated explants - number of contaminated explants)], and the induction of adventitious buds was observed.
Tissue culture of Haemanthus albiflos 229 Note: - very few buds, poor growth; + relatively few buds, average growth; ++ somewhat more buds, slightly better growth; +++ many buds, relatively good growth, but with albino seedlings; ++++ many buds and vigorous growth, no albino seedlings (the same applies to the tables below): -. +. ++, +++, ++++ ()? From Table 1, it can be seen that different 6- and combinations had significant differences in adventitious bud induction rate. Media -8 and -7 significantly increased the adventitious bud induction rate, reaching 100% and 95%, but the growth vigor of adventitious buds on the former was worse than on the latter.
Analysis of the results suggests that medium 1-7, that is, when the 6- and concentrations were 2.0 and 0.1 respectively, was most favorable for the induction of adventitious buds in Haemanthus albiflos. 2.2 Screening of adventitious bud proliferation media: From Table 2, it can be seen that -1 and -2 media significantly increased the proliferation multiple of adventitious buds, among which adventitious buds in -2 medium developed well. They were dark green, robust, and vigorous, and after several subcultures could form a large number of adventitious buds; adventitious buds in -1 medium grew worse than in -2, being yellow-green and growing more slowly; -3 medium significantly reduced the proliferation multiple of adventitious buds, and at the same time callus was prone to differentiating roots after further culture for a period.

How to grow Haemanthus albiflos: cultivation methods and precautions

Haemanthus albiflos is a common herbaceous plant. Its original origin was Africa, and it was later introduced and planted in China. Its distribution is now very wide. Because Haemanthus albiflos has high ornamental value, it attracts many people to cultivate it. Before cultivating it, however, understanding its cultivation techniques is probably a question of greater concern to everyone.

How to grow Haemanthus albiflos

1. For potting soil, use a mixed soil of leaf mold, coarse sand, and peat. During the plant's growing period, fertilize once every ten days, and the amount of fertilizer should not be too concentrated or excessive. In summer and autumn, when the potting soil is relatively dry, water promptly and water thoroughly. In winter, Haemanthus albiflos will briefly enter a semi-dormant state. At this time, water less and place it indoors in a sunny spot.

2. When sunlight is strong in summer, provide shading. In autumn, strengthen light and water and fertilizer management, thereby promoting good development of the inflorescence and favoring the elegant form of the whole plant. The suitable temperature during the growing period of Haemanthus albiflos is 18-24°C, and in winter the temperature should be kept at 13-15°C.

Cultivation methods of Haemanthus albiflos

1. Soil requirements: Haemanthus albiflos likes slightly acidic soil. Moreover, the soil should have good aeration, so slightly acidic sandy soil can be chosen, that is, a mixed soil of leaf mold, peat, and coarse sand. This favors air movement in the soil layer and water permeability, benefiting the growth of Haemanthus albiflos.

2. Temperature requirements: The suitable growth temperature for Haemanthus albiflos is 16-21°C during the day and 10-12°C at night. Because Haemanthus albiflos has extremely poor cold tolerance, the winter temperature must not be lower than 5°C, and it should be placed indoors or in a greenhouse to overwinter.

3. Light requirements: Haemanthus albiflos likes a semi-shaded environment. Especially in summer, Haemanthus albiflos should be placed in a semi-shaded environment and should not be placed in direct sunlight, but it also should not be in a completely dark corner, as this is not conducive to the growth of Haemanthus albiflos.

4. Water: During the growing period of Haemanthus albiflos, keep the potting soil moist, slightly on the dry side, avoid rain exposure, and the potting soil must not become waterlogged, otherwise it will cause bulb rot. Bulb rot is a disease caused by infection by various fungi and a few bacteria that leads to rot of the bulbs of flowers and crops. This can cause young stems to fail to emerge or leaf growth to be hindered, turning yellow to red or green, and finally withering or even dying.

5. Fertilization: During the growing period, apply a nitrogen-phosphorus-potassium compound fertilizer once every half month. This promotes the growth of Haemanthus albiflos and reduces pests and diseases.

Precautions for Haemanthus albiflos

1. Haemanthus albiflos prefers a sunny, warm, and well-ventilated growing environment and is not tolerant of severe cold. When winter is cold, Haemanthus albiflos is most prone to freezing damage. Its leaves will rot, wither, and then fall off due to freezing damage, and the stems of the plant will also become dry and withered.

2. Therefore, in cold weather, place it in a sunny spot on the balcony and provide sufficient sunlight; in cold overcast weather, the plant can be wrapped with plastic film to take anti-freezing measures. Pay attention to ventilation, but do not let the plant face a draft.

Leaf spot disease of Haemanthus albiflos and its control methods

1. The most common disease in the disease cycle of Haemanthus albiflos is leaf spot disease. Haemanthus albiflos affected by leaf spot disease will have its leaves seriously affected, causing them to gradually turn yellow and eventually wither. Sometimes it can cause deformed leaf development or failure to bloom, reducing the normal growth of the plant and its ornamental beauty.

2. Causes: When Haemanthus albiflos shows this condition, it indicates that the plant's growing environment is unsuitable. It may be caused by inappropriate fertilizer or water.

3. We can fertilize the plant on time and in the right amount, specifically once every three months. Haemanthus albiflos has a high demand for light. Except in summer, light should be strengthened in all other seasons. If sunlight is insufficient, the leaves may become too thin, and it may even threaten the health of the plant.

When cultivating Haemanthus albiflos, you must first choose good soil, then adjust light and temperature. After that, water and fertilizer management need to be strengthened, as too much or too little will be unfavorable to its growth. The most common problem when cultivating Haemanthus albiflos is leaf spot disease, so doing a good job in preventing and controlling leaf spot disease is also very important.
