What is the flower language of Cleome hassleriana?
Flower language: The flower language and symbolic meaning of Cleome hassleriana: mystery.
The petals of Cleome hassleriana are light and graceful, and when in full bloom they look like butterflies dancing, which is quite interesting. In summer and autumn they can be used to arrange flower beds and flower borders, and they can also be grown as dwarfed plants for container viewing. In garden applications, because of their tolerance of partial shade, they can be planted under trees or on the shady side of buildings for viewing.
Cleome hassleriana opens in the evening and withers the next day, so it is also called the flower of summer nights; its brief life gives people a feeling of illusory impermanence. This Cleome hassleriana is native to the tropical regions of South America and is a very good pollution-resistant flower, with strong resistance to sulfur dioxide and chlorine gas; it can beautify the environment and is a very good pollution-resistant flower that can also grow well in heavily polluted factories and mines. It is also an excellent nectar plant and can be used to extract high-quality essential oil.
When is Cleome hassleriana sown and when does it bloom?
Sowing: sow in spring from March to April, by broadcasting; because the seeds germinate uniformly, the sowing density should be small, and after sowing cover with 0.2 cm of soil. At 15°C they germinate in 7 to 10 days; after emergence, thin the seedlings and apply fertilizer. They can be transplanted at 2 to 3 true leaves. If sown in autumn in a greenhouse, they bloom in spring.
Blooming: the flowering period is from June to September (late summer and early autumn). Cleome hassleriana is an annual or biennial herbaceous plant, with a plant height of 40 cm--60 cm, flowers 3--6.5 cm wide, and some varieties can reach 1 to 1.5 m tall. Its flowering time is 75 to 110 days, with slight differences from place to place.

What are the planting methods for Cleome hassleriana?
1. What kind of environment is suitable for Cleome hassleriana
The quality of the soil directly affects the quality of Cleome hassleriana seedling development. If the soil is very good and the growing environment is very good, then the workers will have a much easier time tending them. Cleome hassleriana is not strict about soil restrictions, and can grow in sandy gravel soil, yellow mud and clay, but soil with a high sand content has average germination. Cleome hassleriana fears waterlogging, so the terrain is required to be flat and easy to drain. When the dog days come and rainfall increases, water must be able to drain away immediately, otherwise there may be large-scale seedling death. The nursery must focus on good drainage; ordinary soil is about enough, and sunlight duration must be sufficient.
2. Land preparation
1. Plowing: Cleome hassleriana is very sensitive to fertilizer. If the soil has sufficient fertilizer, the flowers will be large and gorgeous and the plants healthy. But the soil of most construction sites is nursery land with average fertilizer, so to get gorgeous flowers, sufficient farmyard manure must be applied before sowing, spreading 3 to 6.5T of cow and pig manure per mu. After applying fertilizer, plow deeply once and harrow finely once, so that the soil and nutrients are evenly mixed together, with no large clods of soil, which facilitates sowing and improves the germination rate.
2. Making beds: In order to facilitate the necessary management work for Cleome hassleriana seedlings during their first-year growth, such as irrigation, weed clearing and fertilizing, Changjing Landscape suggests making the land into standard beds 1.4 m wide and 12 to 20 m long, with the specific size determined by the terrain.
3. How to plant Cleome hassleriana
The seeds of Cleome hassleriana are generally medium in size and have fairly good germination ability, so shallow sowing is recommended, with a soil covering depth of no more than 5 cm. Broadcasting is mostly used for planting; choose a breezy day, mix the Cleome hassleriana seeds into wet sand, and broadcast them onto the ground. After sowing, cover with soil by hand or by mechanical raking, then irrigate once, and in about 6 to 12 days the germination rate can be improved.
4. How to care for Cleome hassleriana
There is very little maintenance and management work during the growing period of Cleome hassleriana. It basically has no diseases and pests, and its growth is vigorous. The main tasks are all concentrated in the flowering time. Before flowering, apply 30 kg of compound fertilizer per mu. Fertilizing before flowering is to prolong the flowering period and make the flowers and colors more beautiful. Do not fertilize during the full flowering period. During the time when Cleome hassleriana is in bloom, it requires more water, so during this period, according to the weather conditions, water at the right time.
