The underside is gray-green, with short soft hairs along the veins. There are 8-10 lateral veins on each side, and the petiole is 8-20 millimeters long, with the leaf scar about half the length of the petiole. The flower buds are ovate, covered with light yellow silk hairs.

The flowers and leaves bloom simultaneously, are bottle-shaped, stand upright on the robust and hairy peduncle, and exude a slight fragrance. The flower has 9-12 tepals.

The outer 3 tepals are sepal-like, purple-green, lanceolate, and 2-3.5 centimeters long, which usually fall off early. The inner two rounds are fleshy, purple or purplish-red on the outside, white on the inside, petal-like, ovate, 8-10 centimeters long, and 3-4.5 centimeters wide.

The aggregate fruit is dark purple-brown, turning brown, cylindrical, 7-10 centimeters long. The mature samara is nearly spherical, with a short beak at the top. It blooms from March to April and bears fruit from August to September.

II. Distribution range

It grows on mountain slopes at altitudes of 300-1,600 meters. This species has been a traditional flower in China for over two thousand years. It is cultivated in major cities across China and has been introduced to cities in Europe and America. Its bright colors are admired both domestically and internationally.

III. Growing Environment

Thrives in warm, humid, and sun-filled environment, with a good tolerance to cold, but not to drought and saline-alkali. It requires a fertile, well-drained loamy soil, and is intolerant to waterlogging.

IV. Propagatio

Common methods include division, layering, and seeding. After flowering, combine with repotting, tip plant upside down, and cut off the root sprouting offspring with a sharp shears or knife for separate planting.

Transplanting can be done in the fall or early spring before blooming. Seedlings should be coated with mud, and larger plants should be moved with a soil ball. Fertilize once before and after flowering, primarily with phosphorus and potassium fertilizers.

Maintain soil moisture during hot summers and dry autumn seasons. Prune dead, dense, and overly long branches before and after flowering. For seeding, collect seeds in September, store in sand during winter, and sow in the following spring. Germination occurs 20-30 days after sowing.

V. Main Value

Economic Value

The bark, leaves, and flower buds of Magnolia liliiflora can be used as medicine. The dried flower buds, known as Xin Yi, have a fragrant aroma and a spicy taste.

They contain volatile oils mainly composed of citral, eugenol, and eucalyptol, which are used to treat rhinitis and headaches, and as analgesic and anti-inflammatory agents.

It has been a traditional Chinese medicine for over two thousand years, and is also used as rootstock for grafting other magnolia plants.

Not only does Magnolia liliiflora have large and beautiful flowers, with graceful forms and a pleasant fragrance, making it highly ornamental and resistant to pests and diseases, but its flower buds, known as Xin Yi, have always been a major medicine in traditional Chinese medicine for treating nasal diseases.

The buds are picked before flowering and dried in a well-ventilated place. Modern research has shown that the volatile oils in Xin Yi can constrict nasal mucosal blood vessels and promote the absorption of secretions, thereby improving nasal ventilation.

For the treatment of acute and chronic rhinitis and sinusitis, take 10 grams each of Xin Yi and Cangerzi, decoct in a gauze bag, take the concentrated juice and drip into the nose 3 to 4 times a day for good results.
