It is a traditional ornamental flower in China and Japan, with leaves that stay green all year round, hence the name Evergreen.

Below, the editor introduces how Rohdea japonica should be cultivated:

The cultivation soil for Rohdea japonica can be made by mixing humus soil, leaf mold, sandy soil, and furnace cinders with fertilizer. All five soil materials should be prepared in advance, exposed to strong sunlight, then finely broken up and sifted before use.

Rohdea japonica has thick, emerald green leaves, and must be fertilized once every 15 days. After normal outdoor cultivation in spring, apply a top dressing about once every 7 days. Stop top dressing before flowering; after fruiting, give large amounts of fertilizer, applying top dressing every few days to make the berries fuller.

Rohdea japonica likes moisture but fears waterlogging, so it should not be watered too much, otherwise the roots rot easily. Water once every 2-3 days.

For the flower pot of Rohdea japonica, it is best to place a water tray underneath, so that water can seep into the soil through the small holes, keeping the potting soil moist at all times.

Rohdea japonica is a flower that likes warmth and moisture, tolerates shade, and fears cold. In summer it should be cultivated outdoors, and a shelter must be set up to shade it from sunlight. Under sunlight, the leaves easily turn greenish-white, and the leaf edges also easily scorch.

Fertilize Rohdea japonica appropriately; during the growing season, apply fertilizer or compound fertilizer solution about once every half month; do not fertilize in winter. When cultivated indoors, place it in a spot with good light.

Rohdea japonica should be pruned in a timely manner, completed before the Start of Summer. When pruning, check front and back, and cut off leaves that are aged, insect-damaged, or cracked.

Pruning for seedling cultivation is an important task, otherwise it is difficult to flower.
