Lisianthus is a perennial plant of the Gentianaceae family with a height of 30-100 cm. The leaves are opposite, broadly elliptic to lanceolate, almost sessile, the leaf base is slightly embracing the stem; the leaf surface is blue-green. The pistil and stamen are obvious, the bracts are narrowly lanceolate, and the petals are arranged in a tile-like shape. Lisianthus has a variety of colors, including single and multiple colors, with single petals and double petals.
Lisianthus is native to the limestone zone between the southern United States and Mexico. Modern lisianthus cultivation has flourished in Japan. Commercial cultivation has begun in the 1960s. The Lisianthus flower color is elegant and bright, and the flower shape is unique and lovely. It is one of the most popular types of potted and cut flowers in the world.
Lisianthus morphological characteristics
Lisianthus is cultivated for one or two years. Opposite leaves, gray-green. Oval, entire.
The plant height of Lisianthus varies from species to species. The corolla is funnel-shaped and has single petals. The flower colors are very rich, mainly red, pink, lavender, purple, white, yellow, and multicolor flowers with various degrees of bordering. According to different varieties, each Lisianthus Flower stems can produce 10-20 flowers, usually with 5-10 flowers on a single branch.
Lisianthus growth habit and growing environment and distribution
Lisianthus loves a warm, humid and sunny environment. More drought-tolerant, intolerant to water and humidity. The suitable temperature for growth is 15-28℃,
The night temperature cannot be lower than 12°C. In winter, the temperature is below 5℃, and the leaves are rosettes and cannot bloom. If the temperature exceeds 30°C, the flowering period of lisianthus is significantly shortened. Lisianthus has strict water requirements and likes to be moist, but too much water is also detrimental to the growth of roots. If the water supply is insufficient, the stems and leaves grow thinly and bloom early. Lisianthus is more sensitive to light, and long-day light can help stem and leaf growth and flower bud formation. Loose, fertile and well-drained soil is required, and the pH value should be 6.5-7.0, and continuous cropping should not be avoided. Eustoma flowers need to go through a period of low temperature and bloom in the high-temperature stage. The natural flowering period of lisianthus is May to July. Annual flowering can be achieved under certain facilities and cultivation techniques.
Lisianthus is native to Colorado, Nebraska, Texas and New Mexico. Since the 1970s, lisianthus has become popular as a cut flower in Japan and North Korea.
Lisianthus efficacy and role
The lisianthus plant is elegant, with fresh and elegant colors. The lisianthus potted plants are used to decorate the room, balcony, or window sill, showing a sense of freshness and elegance. If you cut out a few purple lisianthuses and add white lilies, it is very decent for flower arrangement.
Lisianthus is commonly used for sowing and breeding. Its seeds are very small, usually about 10,000 seeds per gram, so the seeds of lisianthus are mostly coated. The seedling rate of lisianthus seeds after coating treatment is higher. It is best to broadcast indoors from September to October or January to February. The seeds of lisianthus are small, light-loving, and do not need to be covered with soil. The suitable temperature for germination of lisianthus is 22-25℃, and it germinates 12-15 days after sowing. The seedlings grow very slowly after half a month after germination. It takes 120-140 days from sowing to flowering, and 150-180 days for cut flower varieties. In the seedling market, lisianthus also has a small supply of tissue culture seedlings and cutting seedlings.
