It is native to the Mediterranean coast, Europe and Oceania islands, such as Provence, a small town in southern France, and is widely planted. The northern foot of Tianshan Mountain in Xinjiang is at the same latitude as Provence in France, with similar climate and soil conditions. It is a lavender planting base and the hometown of lavender in China. Lavender in Xinjiang has been listed as one of the eight famous varieties in the world. Like to do it. These flowers are spike-shaped and have slender stems. The flowers are covered with star-shaped fine hairs, with purple-blue florets at the tip and gray-green narrow leaves. When they grow up, they can reach 90 cm tall and usually bloom in June. Whenever the wind blows, a whole lavender field fluctuates like a deep purple wave, which is very beautiful. Morphological characteristics [edit this paragraph] Lavender perennial herb or shrub, although called grass, is actually a purple-blue floret. Lavender is clustered and branched, usually growing vertically. According to different varieties, the plant height is 30 ~ 40 cm and 45 ~ 90 cm. In mountainous areas with quite high altitude, a single plant can grow to1m. Leaves alternate, elliptic-lanceolate, or large needle-shaped, and the leaf margin rolls back. Spike terminal, 15 ~ 25 cm long; Corolla lower tubular, upper lip-shaped, upper lip 2-cleft, lower lip 3-cleft; The flowers are about 1.2 cm long and have blue, deep purple, pink, white and other colors. The common color is purple-blue, and the flowering period is from June to August. The whole plant has a faint aroma with a slight woody sweetness. Because the villi on flowers, leaves and stems contain oil glands, they will burst when touched lightly and release fragrance. Cultivation and Utilization of Lavender Lavender is the most commonly cultivated variety in this genus, and many different varieties have been cultivated at present. Other species that are often planted for viewing are Spanish lavender, lavender with teeth leaves and lavender with fern leaves. Lavender spikes can be used as dried flowers and decorations. Lavender, fragrant flowers and flower buds can be used as incense pots and sachets, and dried flowers can be sealed as sachets. Putting sachets in the closet can make clothes fragrant and prevent insects from eating them. The commercial cultivation of lavender is mainly to extract lavender essential oil from lavender flowers, which can be used as disinfectant and aromatherapy essential oil. Spanish lavender (native to China) was introduced into Australia and became an invasive species in all parts of Australia. Lavender in cultivation garden: Lavender flowers in Spain secrete a lot of nectar, which can produce high-quality honey. Countries around the Mediterranean are the main producing areas of lavender honey. Lavender flowers can be used as lavender jam, and can also be used as materials and decorations for western pastry cakes. Lavender can be used as a spice when cooking food, and can also be used alone or mixed with other herbs to make Provence spices. History In ancient Greece, lavender was called Nardus, sometimes referred to as Nard for short. The name comes from a Syrian city called Nalda. In ancient Rome, a pound of lavender could be sold for 100 dinar, which was about equivalent to the salary of a farm worker at that time, or the reward of a barber for cutting 50 people's hair. The Romans put lavender and various herbs in the bath water, and they spread this bathing method to England. In the era of the Black Death, glove makers in Grass, France, often soaked leather with lavender oil, so many workers escaped the plague. There may be some truth in this story, because plague germs are spread by fleas, and lavender can drive away fleas.

Question 9: What is lavender bud like? I haven't seen your picture, so it's hard to judge. I'll give you a picture of lavender buds. Just compare it yourself.
I will give you some information about agriculture.
Lavender likes sunshine, is heat-resistant, drought-resistant, cold-resistant, barren-resistant and salt-tolerant, and the cultivation site needs sufficient sunshine and good ventilation. Time from sowing to flowering (or harvesting): 18 ~ 20 weeks. Lavender should be cultivated in large containers. But in order to prevent it from getting too wet, you can use a pottery jar or a smaller plastic jar, and don't use a big jar unless it is quite large.
Lavender can't stand high temperature and humidity, and it will die after being flooded for a long time. When planting outdoors, be careful not to let the rain directly rain on the plants. After May, it is necessary to move the place out of direct sunlight, increase ventilation to reduce the ambient temperature and keep cool, so as to spend the hot summer safely. Pay attention to sunshine, moisture, temperature and patience.
1. Soil: Suitable for weak alkaline or neutral sandy soil. Special attention should be paid to the selection of substrates with good drainage, which can be mixed with 1/3 pearl clay, 1/3 vermiculite and 1/3 sphagnum moss. If it is cultivated in the open field, pay attention to the drainage of the soil, and raise the mound into a border before planting.
2. Watering: Lavender doesn't like to keep water in its roots. After the first watering, water should be supplied when the soil is dry. The surface medium was dry and the inside was moist, and the leaves wilted slightly. Water in the morning, avoid the sun, and don't splash water on leaves and flowers, otherwise it will rot and breed pests and diseases. Continuous humid environment will make the roots grow poorly, there is not enough air to breathe, and even the whole plant will die suddenly. This is often the reason for the failure of lavender cultivation.
3. Illumination: Lavender is an all-day plant, which needs sufficient sunshine and a suitable humid environment. The environment that can give full sunshine is better, and it can grow in half sunshine, but there are few flowers. In summer, at least 50% sunlight should be blocked, ventilation should be increased, and the ambient temperature should be lowered, so that although the growth is weak, it will not die. Lavender can grow well on the flat ground in winter, so it should be cultivated in sunny places.
4. Temperature: Lavender is semi-heat-resistant, so it is cool. It likes warm in winter and cool in summer. The suitable growth temperature is 15 ~ 25℃, and it can grow at 5 ~ 30℃. Limit temperature: above 35℃, above 38 ~ 40℃ for a long time, and the top stems and leaves turn yellow. In northern winter, when the temperature is lower than 0℃ for a long time, the seedlings begin to hibernate, during which the seedlings can tolerate the low temperature of -20 ~-25℃.
5. Fertilization: When fertilizing, you can put bone meal as the base fertilizer (once every three months) in the pot soil, and then apply a fertilizer with higher phosphorus fertilizer, such as Huabao No.3 (20-30-20). Apply light fertilizer.
6. Pruning: Lavender flower essential oil is the most abundant, and it is mainly used in flowers or inflorescences. In order to facilitate harvesting, some small inflorescences in the early stage of cultivation may wish to be leveled with scissors, and the newly grown inflorescences are of the same height, which is conducive to one-time harvesting. Some varieties can be as high as 90 cm, and this method is also used to make plants low, promote more branches and flowers, and increase harvest. Pruning must be carried out after flowering, and the plant can be pruned to 2/3 of its original size, so that the plant type will be stronger and conducive to growth. Pruning should be carried out in cold seasons such as spring and autumn, generally in spring, and pruning in autumn will affect cold tolerance. When pruning, be careful not to cut off the lignified part, lest the plant weaken and die.
Seven common diseases:
When one-year-old sowing seedlings or cutting seedlings are damaged, the plants wilt, lose water, the leaves are dull, and the top of leaves and branches bend downward, which is most obvious in bud stage. Light can recover at night, and heavy will die in two or three days, with rotten roots and brown shiny stems. In addition to pathological manifestations, seedlings over three years old have wilting symptoms at the center or edge of the plant, which gradually develop inward and outward, and the branches wilt and die, and finally the whole plant dies. The degree of damage varies with the age and variety of trees. Generally, it starts in May and reaches its peak in July and August. The incidence of lavender in France is serious, and the varieties of 2-4 17 in the former Soviet Union are relatively light.
