1. Evening Primrose (Mountain Sesame/Night-blooming Jasmine) Cultivation Method
: A biennial herbaceous plant belonging to the Onagraceae family. Flowers are solitary in the leaf axils, pale yellow, and 5 cm in diameter. The capsule is cylindrical, and the seeds are small.
Flowering period is June to August, and fruiting period is August to September. It is highly adaptable, not particular about soil type, and tolerant of poor soil, drought, and cold.
After sowing, the soil should be kept moist to allow the seeds to absorb water and germinate. Seeds
germinate . It is a medicinal plant with multiple uses. The seed oil is not only used in medicine but also as a nutritional supplement and
in refined cosmetics. Aromatic oils and extracts can be extracted from the flowers. The flowers are large and beautiful, with a pleasant fragrance that opens at night, making them suitable for decorating night scenes and
complementing other landscaping materials.
It thrives best in well-ventilated, bright, loose, fertile, and well-drained sandy loam soil in gardens. It can also be potted and placed on
balconies for viewing; under the quiet moonlight, its delicate fragrance is refreshing. Evening primrose has a strong self-seeding ability; after one planting, its
self-seeded seedlings will sprout annually and bloom continuously. For artificial propagation, autumn sowing in October is recommended. After winter, the seedlings should be temporarily
planted in a sunny seedbed, covered at night for frost protection. The following spring, they can be transplanted outdoors or potted. Sowing can also be done in early spring (March), resulting in flowering that year, but the flower
quality will not be as good as autumn sowing. When seedlings have 2-3 true leaves, transplant them once to promote vigorous growth. When they have 6-7 true leaves,
transplant them again. Evening primrose has a well-developed taproot; generally, after successful potting, pinching can be done to encourage branching and more flowers. During the growing season, depending on
the vigor , apply a suitable amount of organic or inorganic liquid fertilizer every two weeks, keeping the potting soil consistently moist. After flowering, promptly remove spent blooms to reduce
nutrient consumption and encourage further flowering. For home cultivation, seeds can be sown indoors in pots in early spring. Because the seeds are small, sowing should not be too dense, and the soil covering
should not be too thick. When the seedlings have 6 true leaves, remove the entire clump and transplant it with soil into the ground or pots. It will bloom in May and continue to bloom until
the end of October.
2. Violet Cultivation Method
[Other Names] Grass Violet, Grass Osmanthus
[Ecological Habits] Native to the Mediterranean coast of Europe, commonly cultivated in gardens worldwide. Prefers cool, sunny environments, but can tolerate
partial shade. Optimal growth temperature: 15-18 degrees Celsius during the day and about 10 degrees Celsius at night. Can tolerate temperatures as low as -5 degrees Celsius in winter. Requires loose,
fertile , moist, deep, neutral or slightly acidic loam. This perennial herbaceous flower is often cultivated as a biennial. [Cultivation Management]
Propagation is by sowing in autumn. Optimal germination temperature is 16-18 degrees Celsius, germination takes about 4 days. Overwinter in a cold frame, and transplant outdoors the following spring. Flowering occurs around May
1st . This is an annual variety that can be sown year-round in cool summer regions, providing flowers annually. Cultivation should not be too dense, and
fertilization is necessary during the growing season. With proper care, it will bloom in mid-April. After flowering, prune the flower stalks and apply fertilizer 1-2 times.
A second flowering is expected in June-July
. Seedling management: Transplant seedlings when they have 3-4 true leaves. Use pots with a diameter of 25cm, a height of 17cm, and
a base diameter of 15cm. Add 20% by volume of well-rotted horse manure as base fertilizer to the soil during transplanting. Violets
grow relatively quickly and
therefore require ample fertilizer. In addition to applying a diluted liquid fertilizer weekly during the vigorous growth stage, spray with a 0.1% potassium dihydrogen phosphate solution 3-4 times after the plant produces flower stalks. Violets prefer slightly moist to dry soil; therefore, except for
watering thoroughly after transplanting, avoid keeping the soil too wet. Because the seedlings need to be hardened off in the early stage of growth, the soil should be
kept slightly moist to dry. In the later stage of growth, the amount of watering should be increased, otherwise the plants will grow too short. In addition, when the seedlings
are about 6 cm tall, pinch off the top once to promote branching and increase the number of flowers.
Flowering period management: After the violet flowers, water should not be lacking and no further fertilization is needed. It should be placed in a cool place with a suitable temperature of
12-18℃, otherwise the flowers will wither quickly. The spent flowers should be cut off in time to prevent the plant from consuming too much
nutrients .
Pest and disease control: In greenhouse cultivation, damping-off, downy mildew and aphids are the most serious diseases that damage violets. Damping-off:
(1) Seed disinfection: Before sowing, soak the seeds in 40% formaldehyde 400 times solution for 25 minutes or soak them in 50℃ warm water for 10 minutes.
After disinfection, dry them and sow them. (2) Soil disinfection: Use 70% chlorine-free nitrobenzene, 2 kg per mu, add an appropriate amount of fine soil and mix and spread, then
sow. (3) Eliminate diseased plant debris. Downy mildew: Promptly prune and destroy diseased leaves to reduce the source of infection and maintain ventilation and light penetration.
Spray with 50% pyrethroid insecticide at a dilution of 500 times during the disease outbreak period. Aphids: Spray with 20% pyrethroid insecticide at a dilution of 2000 times or 40% dimethoate at a dilution of 400 times.

3. Poppy Cultivation Methods
　　Morphological Characteristics: An annual or biennial herbaceous plant. The plant grows to 30-90cm tall, with slender stems and weak branches. The entire plant is covered in downy hairs and contains
white latex. Leaves are alternate, irregularly pinnately divided, and serrated. Flowers are solitary at the stem apex, with long pedicels.
Flower buds droop, and after blooming, the pedicels stand upright, and the flowers face upwards. Petals are thin, glossy, and silky. Flower diameter is over 4.5cm. Petals are broadly obovate or
nearly round, entire or slightly lobed. There are semi-double and double-flowered varieties. Flower colors include deep red, bright red, pink, purplish-red, pale yellow, white
, and mixed colors; some have different colored edges, and some have black spots at the base of the petals.
　　Growth Habits: Prefers full sunlight and warmth; not cold-hardy or heat-tolerant; dislikes high humidity; not particular about soil type, but
grows best in well-drained, fertile sandy loam. Flowering period is between spring and summer.
Propagation and Cultivation:
Germination conditions (temperature, soil covering, and light requirements, etc.): 18-20℃, light covering.
　　Germination time: 7-12 days.
　　Optimal growth temperature (day/night temperature): 10-13℃.
　　Light requirements and other growth conditions: Full sun.
　　Time from sowing to flowering (or harvesting): 10-11 weeks. Seeds are small, and direct sowing is generally used for propagation.
Sowing can be done in spring or autumn. Autumn sowing requires covering with mulch for warmth before winter. Flowering occurs the following June. Direct sowing in flower beds or furrows in late March
can also result in flowering in June. Keep the soil moist during the growing season, generally watering once every 10 days.

4. Strawflower Planting Method:
Sowing is suitable in autumn, winter, or early spring, but autumn and winter are preferred. The optimal germination temperature is 15-20°C.
It requires good sunlight and prefers warmth; the optimal growing temperature is 12-25°C. During the rainy season, ensure good drainage to prevent root rot caused by waterlogging
. Apply top dressing every 20-30 days during the growing season; a combination of phosphorus, nitrogen, and phosphorus fertilizers or various organic fertilizers are ideal.
Pinch off the growing tip once after establishment to encourage branching and more flowers.
The plant grows to 70-120mm tall, with a thick, rough, and seemingly hairy stem. The leaves are linear or lanceolate. The terminal inflorescence is solitary, with flowers 3-6mm
in diameter . The petals are composed of multiple layers of bracts surrounding the terminal inflorescence; the outer bracts are short and arranged in an imbricate pattern, while the inner layers
of bracts elongate into petal-like shapes, pale red or yellow, thickening at the base with a greenish tinge, dry and hard. The small flowers cluster into a yellow disc, about 2mm
in diameter .
Flower colors include white, light pink, rose red, purplish red, as well as light yellow, deep yellow to deep maroon.
Flowering period: from winter to late spring, approximately from December to May of the following year.

6. Zinnia Cultivation Method:
Zinnia, also known as Step-by-Step, Opposite-leaf Plum, and Five-color Plum, is an annual herbaceous flowering plant belonging to the genus Zinnia in the Asteraceae family. The plant grows to a height of 40-120
cm, with an erect stem covered in short hairs and a rough surface. Leaves are opposite, ovate or elliptical, with the leaf base clasping the stem. The flower heads are 5-15 cm
in diameter , borne at the branch tips, and have long pedicels. Ray florets are in multiple whorls, with obovate petals
that curl backward at the tips, and come in white, yellow, red, pink, purple, green, orange, and other colors. Disc florets are concentrated in the center of the flower head. The involucre is multi-layered and bell-shaped,
joined at the base. Ray florets can also produce seeds, with achenes that are ovate or bottle-shaped, tapering at the apex and slightly concave in the middle. Disc florets produce
achenes that are elliptical, flat, and small. Zinnia fruits ripen successively from August to October, and the seeds have a lifespan of up to 3 years.
The flowering period of Zinnia is from June to October.
　　Through long-term artificial hybridization and selection, zinnias have developed into numerous cultivars, broadly categorized into
three types: large-flowered tall-stemmed, medium-flowered medium-stemmed, and small-flowered clump-forming. Large-flowered tall-stemmed varieties reach 90-120 cm in height, with few branches and terminal inflorescences reaching 12-15
cm in diameter. Medium-flowered medium-stemmed varieties reach 50-60 cm in height, with more branches and inflorescences 6-8 cm in diameter,
slightly flattened at the top, giving the entire inflorescence a nearly oblate shape. Small-flowered clump-forming varieties reach 40 cm in height, with many branches and numerous flowers per plant
, but the inflorescence diameter is small, only 3-5 cm, with ray florets spreading flat without curling, giving the inflorescence a spherical appearance.
A new dwarf type of zinnia, developed in the 1970s, features spreading, semi-circular branches, flowers 7-8 cm in diameter, and a plant height
below 30 cm. The shortest miniature variety reaches only 20 cm in height, with flowers approximately 4 cm in diameter.
　　Zinnias originated in Mexico and other regions, and are now widely cultivated worldwide. They are robust, adaptable, with deep root systems and
sturdy stems that resist lodging. They prefer sunlight and warmth, are not cold-hardy, tolerate poor soil and drought, but dislike continuous cropping and hot, humid conditions.
They grow well in fertile, deep soil when planted in the ground, and thrive
best .
　　Propagation of zinnias is usually done by sowing. The suitable germination temperature is 20℃～25℃, and
germination occurs . Sowing in the open field should not be done too early; if the temperature drops below 15℃ after emergence, the seedlings will stop growing and will remain
underdeveloped, becoming stunted. When seedlings reach 5～8 cm in height, they should be divided and
transplanted . Propagation can also be done by cuttings from side branches after mid-June; care should be taken to provide shade and protection from rain to prevent the cuttings from rotting. For potted zinnias,
choose new dwarf varieties and large-flowered dwarf types. Sow seeds in pots in a greenhouse in early February, transplant seedlings into
pots with an inner diameter of 10 cm in mid-March, one seedling per pot, and then transplant them into pots with an inner diameter of 18 cm in early April for final planting. Under stable room temperature,
sufficient , good air circulation, and appropriate watering and fertilization, zinnias will bloom and be on display around May Day.

7. Sweet Alyssum Planting Method
Other names: White
Alyssum Family: Brassicaceae Genus: Sweet Alyssum
Germination conditions (temperature, soil covering, and light requirements): 20-22℃
Germination time: 8-10 days
Sow seeds evenly in Cuiyun Liang soil, avoid direct sunlight, cover slightly with soil, place in a cool, moist place. To promote germination, apply
a 500-fold diluted solution of styrax B-1. Germination takes about 5-8 days. After germination, move to a sunny location. When the plants reach 5-6 cm in height,
transplant well-drained, well-aerated, and sterilized Cuiyun Liang soil. Mix in traditional fertilizer as a base fertilizer before transplanting. Prefers well-ventilated, sunny, and warm
locations. A long-cycle crop; apply traditional fertilizer once a month. Light requirements and other growth conditions: Full
sun
Optimal growth temperature (day/night temperature): 13-21℃
Time from sowing to flowering (or harvest): 8-9 weeks
Habit: A perennial herb, often cultivated as an annual. It is robust and relatively cold-hardy, but dislikes heat and
prefers , but should not be overwatered. Flowering period is from March to June.
Cultivation: Propagation is by sowing or cuttings. Autumn sowing is recommended, as seedlings emerge quickly and uniformly. In northern regions, they can overwinter in cold frames. Cuttings are best
taken , selecting vigorous branches. When seedlings have 4-5 true leaves, they should be planted in pots. During the growing season, attention should be paid to watering,
fertilizing, and loosening the soil. After flowering, flower stalks should be pruned, topdressed, and placed in partial shade.
Pests and diseases: It is relatively resistant to pests and diseases.
Application: Sweet alyssum has a small plant size, making it ideal for potted cultivation.

8. Phlox Planting Methods
　　: Sowing and Seedling Raising: The seeds are small and can be directly sown in seedling trays using a lightweight sowing medium. After sowing, lightly cover with soil, often
using fine vermiculite to help maintain moisture, and spray with fungicide to prevent seedling disease. The optimal germination temperature is 20-22
degrees Celsius. Soil temperature has a significant impact on seed germination and should be carefully controlled. Seedlings generally emerge in 7-14 days. Note that seedlings
are not tolerant of transplanting. The timing of sowing and seedling raising varies depending on the location. In northern regions, sowing can be done in early February, with flowering after May. Cool summers
are required . In the middle and lower reaches of the Yangtze River and areas south of it, due to hot summers, autumn sowing is often used, with seedlings overwintering
above 0 degrees Celsius, allowing them to flower in spring. Phlox prefers ample sunlight and well-drained humus soil.
　　Transplanting/Potting: Phlox seedlings are not tolerant of transplanting, so it is better to transplant early rather than late, and the root system of the seedlings should be kept intact as much as possible.
Transplanting is typically done within 4 weeks of germination. The 'Palona' variety is best suited to small pots of about 10 cm in diameter and a well-draining,
loose, and breathable potting mix.
　　Temperature control: Seedlings germinate at a relatively high temperature, around 22 degrees Celsius. Initially after transplanting, it's best to maintain a temperature of 18 degrees Celsius.
Once the root system has elongated, the temperature can be lowered to around 15 degrees Celsius. Flowering should occur in about 9-10 weeks. Maintaining a lower temperature
helps form a good plant shape. Phlox can tolerate temperatures as low as 0 degrees Celsius, but its growing season is relatively long.
　　Cultivation management: Phlox thrives in sunny, cool environments, eliminating the need for growth regulators to
control plant shape. If environmental conditions are unfavorable, spraying with growth regulators 1-2 times can prevent excessive growth. Maintaining
good to prevent overcrowding, which can negatively impact plant shape and lead to pests and diseases. The plant is short and has hairy foliage; therefore, watering and fertilization should
avoid soiling the leaves to prevent rotting. The entire growth and development period is 10-14 weeks, depending on the size of the pot, light conditions
, and seedling time. Detailed introduction
of Fragrant Phlox
: Mixed-color racemose inflorescences, plant height 40 cm, flower diameter 2-3 cm, fragrant, sown in spring and autumn, flowering period March to November, growing period
55 days.

9. Hollyhock Cultivation Methods
【Family and Genus】Malvaceae, Althaea
【Ecological Habits】Hallyhock originated in China and other parts of Asia. It was first discovered in Sichuan, hence the name "Hallyhock." It prefers sunlight and does not tolerate shade.
Its underground parts are cold-hardy and can overwinter outdoors in North China. It is not particular about soil type, but grows best in loose, fertile soil. It is an annual
herbaceous plant.
【Cultivation and Management】It is usually propagated by sowing. The germination temperature is 18-25℃. Direct sowing is done in June-July, with a light covering of soil
. Autumn sowing is also possible. It can also be propagated by division and cuttings. Seeds mature in August and September and can be sown immediately after harvesting. Flowering
occurs ; spring sowing may not result in flowering in the same year, with seedlings emerging after 7 days. When seedlings have 2-3 true leaves, they should be transplanted once, increasing the spacing between plants.
In winter, lightly cover with straw or leaves for frost protection. Transplant to the next spring when new shoots emerge. For small-scale planting, hollyhocks can be directly sown.
After emergence, weak seedlings should be removed appropriately. Division propagation is carried out in spring. Water hollyhocks appropriately after planting. Before flowering, apply top dressing 1-2 times in conjunction with
weeding cultivation. Water appropriately when old roots sprout in early spring. Generally, rejuvenate every 4 years. Hollyhocks are susceptible to leaf rollers,
aphids, and spider mites. Older plants and those in dry weather are prone to rust disease, so timely prevention and control are necessary.
