Hyacinth, also known as daffodils or five-color daffodils, is a perennial plant belonging to the Liliaceae family. Its scientific name is *Hyacinthus orientalis*. This bulbous plant is native to regions in Africa, Europe, and Asia Minor. It thrives in cool climates with high humidity and plenty of sunlight. Hyacinths are relatively cold-tolerant and require well-drained, loose, and fertile sandy soil. They should be planted in areas that avoid heavy, wet soils.
The bulbs of hyacinths are either round or flat, covered with a thin membrane that can be blue-violet, pink, or white. The color of the membrane often corresponds with the flower color. The leaves are basal, typically 4–6 in number, lance-shaped, with a rounded tip, thick, and glossy. The flowering stem grows between 20–45 cm tall, hollow, and bears a raceme with more than 20 flowers. The flowers are needle-shaped, drooping or slanted, with a slightly swollen base and 4–6 lobes that curl outward. Their colors range from red, yellow, pink, white, black, to purple.
Propagation of hyacinths mainly occurs through bulb division, usually done from September to October. For varieties that don’t divide well, bulb cuttings can be used. The bulbs are sliced radially, dried for 1–2 hours, and then flattened. After drying, small bulblets develop at the cut sites and can be separated and replanted in September or October. Seed propagation is another method, though it takes 4–5 years for the plants to bloom.
In open field cultivation, hyacinths need rich soil with adequate base fertilizer. Hoe planting or ditch planting methods are common. The soil depth should be about twice the height of the bulb. After planting, water them properly and cover them in winter to protect the bulbs and ensure strong root development for the next season’s bloom. Applying top-dressing fertilizer before and after flowering helps enhance blooming and bulb growth. After the foliage yellows in early summer, dig up the bulbs, dry them, and store them in a cool place.
For potted hyacinths, choose large, healthy bulbs and plant them in September. Place them in a sunny location. Move them indoors when temperatures drop in January, keeping them at 5–10°C to encourage root growth. Gradually increase the temperature to promote shoot development. Once the leaves grow to a certain height, raise the temperature further and provide ample light to make the stems and leaves strong and vibrant.
Hyacinths can also be grown in water. Use wide-mouthed glass bottles, placing bulbs slightly larger than the bottle opening on top. Once roots form, they will reach into the water. After one month, moss can be added around the bulb. Change the water every 3–4 days during the growing period. Alternatively, they can be placed directly in narcissus pots, similar to daffodils.
Common diseases include leaf spot, which spreads through infected bulbs. Symptoms include yellow-green streaks along the leaf veins, leading to wilting in severe cases. Infected plants should be removed and destroyed. Another disease is Sclerotinia, where bacteria enter through the bulb, causing oily lesions that later turn gray or brown. Early treatment includes spraying 50% Protopine wettable powder diluted 500 times or 50% carbendazim wettable powder diluted 600 times. Soft rot is another issue that may affect the bulbs.
Hyacinths are popular spring-blooming bulbous plants, known for their early flowering, compact size, and vibrant colors. They are ideal for container gardening, flower beds, garden borders, or ornamental displays. Commonly cultivated types include Spanish hyacinths and Roman hyacinths. With proper care, these beautiful flowers can add charm and elegance to any garden or indoor space.
