I. Overview of Varieties

Oxalis shamrock, scientifically known as *Oxalis violacea* (also referred to as 'Purple Leaves'), is also commonly called *Oxalis sinensis* or simply *Oxalis shamrock*. It belongs to the family *Oxalidaceae*, which includes various species of wood sorrels.

Characteristics: This perennial herb typically grows between 15–20 cm in height, featuring spindle-shaped or elongated oval tubers. The leaves are basal, with long petioles and three-lobed leaflets that are stalkless, triangular, or broadly ovate in shape. The upper surface of the leaves is purplish-red, often covered with fine white hairs. The calyx leaves can reach up to 5–10 cm in length, and the plant produces corymbous inflorescences with 5–8 flowers. Each flower has five pale pink or lavender petals and blooms from April to November. In midsummer, the plant may grow slowly or enter dormancy. The fruit is a capsule, and both the flowers and leaves are highly sensitive to light—opening during sunny days and closing at night or on cloudy days.

Origin and Growing Conditions: Native to South America, particularly Brazil and possibly Mexico, this plant is a rare and attractive ground cover with striking foliage. It thrives in warm, moist environments with well-drained, humus-rich sandy loam soil. It can tolerate full sun, partial shade, or even light shade, with an optimal temperature range of 24–30°C. Growth slows down or it goes dormant during the hot summer months, and after winter frosts, the above-ground parts wither. However, the rhizomes survive underground and sprout new leaves in March of the following year.

Propagation Methods: Oxalis can be propagated through runners (ramets), seed sowing, or tissue culture. Ramet propagation can be done throughout the year; when planting, you can dig up the runners, split the bulbs, or cut them into pieces, ensuring each piece has at least three buds. These can then be placed in a sand bed for rooting before transplanting. Seed propagation is best done in spring, with germination occurring within 10–12 days at a temperature of 15–18°C. Tissue culture is another viable method under suitable conditions.

Care Tips: During the growing season, *Oxalis oleifera* should be kept consistently moist, fertilized every two weeks, and provided with some shade during the hottest part of the summer.

II. Garden Applications

The unique leaf shape, deep purple color, and contrasting white flowers make *Oxalis* a visually stunning plant. Its elegant form and vibrant color create a strong visual impact. At the Fifth China Flower Expo in September 2001, it received significant attention, with experts praising it as an excellent ornamental plant with great potential for widespread use.

Beyond being a popular potted plant, *Oxalis* is widely used in gardens, lawns, residential areas, and along roadsides and riverbanks to create beautiful purple color blocks. When planted alongside other green or colored plants, it forms dynamic, high-contrast color patterns that add depth, layering, and sophistication to landscapes. Its ability to blend with different elements makes it ideal for creating visually striking and harmonious outdoor spaces. With its dignified appearance and natural beauty, *Oxalis* enhances the connection between humans and nature, making it a top choice for both gardeners and landscape designers.

Ginger Granules

Dried ginger granules are a finely ground form of dried ginger root, offering a balance between potency and texture. These granules, larger than Ginger Powder, provide a robust and concentrated flavor while retaining a slightly coarser texture.

Their versatility shines through various culinary applications. Dried ginger granules dissolve readily in liquids, making them perfect for steeping in teas or infusing cooking liquids for soups, stews, and marinades. They also serve as a versatile seasoning, adding a pronounced ginger flavor to dishes.
