The petals are divided into two layers, with three petals in the inner layer and three petals in the outer layer. The outer petals are longer and more convex than the inner petals.

Propagation and cultivation: Snowdrop is mainly propagated by ramets and seeds. The period of ramet propagation is that after the leaves have withered and the plants begin to hibernate, the small bulbs attached to the mother bulbs are peeled off and propagated with these small bulbs. When propagating with seeds, you can sow them in spring or immediately after the seeds are ripe. Professional growers or amateurs sometimes use a method called "scale propagation" to propagate a large number of seedlings of specific varieties.

Plum blossoms are native to southern China and have been cultivated for more than 3,000 years. There are many kinds of plum blossoms, both ornamental and fruit trees. Many types are not only cultivated in the open field for viewing, but also planted as potted flowers to make plum piles. Flowers can be refined, and flowers, leaves, roots and seeds can be used as medicine. The fruit can be eaten, pickled or processed into Senecio scandens, or smoked into ebony, which has the effects of relieving cough, stopping diarrhea, promoting fluid production and quenching thirst. Plum blossom can resist the harm of root-knot nematodes and can be used as the rootstock of drupe fruit trees.
Plum blossom is the first of the top ten famous flowers in China.

Every year, China imports a large number of cut branches of North American holly (called red beans in the market) from Holland and other countries, and puts them on the flower market, which is very expensive. In 2006, Hangzhou Runtu Horticultural Science and Technology Co., Ltd. introduced '(Ostwick' and other North American holly ornamental varieties.
