I. Physical Characteristics

The plant ranges in height from 40-100 cm. Its heart-shaped leaves grow in pairs and have blunt teeth. The seeds of the shellflower are triangular. The seedlings emerge around a week after sowing, but their growth is slow, only developing true leaves after around 20 days.

They remain small even after a month. After about two months, the plant starts to take shape and begins to flower around the third month. The small trumpet-like structures are its calyxes.

The small flowers are white, arranged in whorls of six, with a shell-like, fragrant green calyx. The flowers bloom from June to July.

The flower has a lip-shaped corolla, and a green calyx resembling a shell, giving the plant its name. The plant has a straight stem, a four-sided stalk, and weak branching power.

II. Growing Environment

IV. Propagation

Shellflowers are propagated by sowing seeds, which can be done in autumn, winter, or early spring.

Propagation by seed can be done in spring, summer, or autumn. The optimal temperature for sowing is 15-25°C. Germination occurs in about a week. When the plant has 5-6 true leaves, it can be transplanted.

The best soil for cultivation is fertile, loose, and well-drained. The soil should not be too sticky, as this will hinder sprouting and slow growth. After successful transplantation, start fertilizing once every half month, and stop fertilizing after the plant flowers.

To encourage branching, you can pinch the plant. Shellflowers are robust and rarely affected by pests, but beware of the potential harm from leaf miners. For viewing purposes, you can sow in stages.

V. Pest Control

Fertile, well-drained soil is crucial. After transplanting 5-6 leaf seedlings, fertilize and water the plant. To encourage branching, pinch the plant in its early stages. This plant is relatively easy to manage.

It grows strong and is rarely diseased, but leaf miners may occasionally appear, so preventive measures should be taken.
