Penglai pine [Liliaceae] [asparagus]

Latin name: asparagus

Distribution of origin:

Originated in Natal, South Africa. It is widely planted all over the world.

Morphological characteristics:

Penglai pine stands upright, 30-60 cm high, and is a perennial evergreen shrub. There are small tuberous roots. There are many tufted stems, many branches, grayish white, woody at the base, leaflike or spiny. The new leaves are bright green and the old leaves are white and powdery. The thallus is oblate, clustered and spherical, and it is planted on lignified branches, and it is dark green. Flowers reddish to white, fragrant, flowering in July-August.

Growing habits:

Like warm and humid semi-cloudy environment, drought-resistant and cold-resistant. Not strict with soil, like sandy loam with good ventilation and drainage and rich humus. The optimum growth temperature is 20-30℃, and the overwintering temperature is 3℃. Penglai pine is often propagated by ramets. You can change pots in spring and summer. Take the densely growing old plants out of the pot, cut the underground roots into several clumps, so that each clump contains 3-5 branches (pay attention to minimize root damage), plant each clump into a pot filled with new culture soil, water it, and place it in a semi-shady place to resume growth. You can also sow and reproduce, but the growth is slow.

Garden use:

Very suitable for potted plants. Flower beds can also be arranged in warm places. Simple cultivation and management, good shade tolerance, suitable for medium and small potted plants and indoor layout. It is also an excellent material for arranging flowers and lining leaves.

Breeding and cultivation:

Multi-line ramet propagation can also be sown, but the growth at seedling stage is slow. Water fully during the growth period, and gradually reduce watering when the temperature drops in autumn. In order to make the branches and leaves flourish, nitrogen fertilizer and potassium fertilizer can be applied once every 15 days. Potted Penglai pine is generally mixed with humus soil, land and river sand as matrix, and slightly decomposed base fertilizer is added when planting. Spring and summer is the peak season for its growth, which requires sufficient water, but it is not suitable to accumulate water in the basin soil to avoid root rot; After the end of autumn, the watering amount should be gradually reduced to keep the basin soil slightly wet. In order to make the branches and leaves flourish, we should pay attention to supplementing nutrients during the growing period, and generally apply liquid fertilizer 1-2 times a month. It likes semi-shade, and it should pay attention to shade in hot summer to prevent the sun from exposure, so as not to burn or yellow branches and leaves. There are fewer pests and diseases in Penglai pine, but red spiders and scale insects may occur when it is hot and dry, so we must pay attention to spraying. Penglai pine has regular plant shape and strong branches; The leaves are spherical, soft, green and dripping, both rigid and flexible, and are deeply loved by people.
