Blood Grass, also known as Salt Cloud Grass, Salt Cloud Ginseng, Spatulate Leaf Grass, and矶松, belongs to the Plumbaginaceae family and the Limonium genus. Because the flowers of Blood Grass are tiny, dry and membranous, with elegant colors and a long ornamental period, they are often used as companion flowers in flower shops, similar to Baby's Breath. In addition to being used as fresh cut flowers, they can also be made into natural dry flowers, and their uses are becoming more and more widespread.
The most commonly cultivated variety is the Deep Wave Leaf Blood Grass. Although it is a perennial herbaceous plant, it has the same growth and development characteristics as autumn-sown biennial herbaceous plants: it does not bloom or the blooming is significantly inhibited under high temperatures; if cultivated at night temperatures below 16°C, it blooms well; however, one point to note is that if seedlings are exposed to low temperatures during the seedling stage, they will also bloom even under high temperatures later. Deep Wave Leaf Blood Grass is generally sown in autumn, and after forming a rosette with 50 to 60 leaves, most of the plant's growing points die. At the same time, the axillary buds grow sequentially from the upper part after forming scaly leaves; the plants that have received low temperatures form flower stems after the scaly leaves and elongate from the upper part, with the more thoroughly the plants receive low temperatures, the more flower stems elongate.
Summer-sown Deep Wave Leaf Blood Grass grows in a rosette shape from autumn to winter. In warm regions, early varieties begin to bolt from the end of December to the beginning of January, and maintain this form through winter. When the temperature rises in March, they start growing and differentiate flower buds. Late varieties start bolting and differentiating flower buds as the temperature rises in March. From the beginning of bolting to flowering, early varieties maintain a night temperature of 10°C for about 40 days; if placed in an unheated greenhouse from February to March, it takes 80 to 90 days. The low temperature required for bolting and flowering: seedlings with 6 leaves or fewer, exposed to 11°C-13°C temperature for 3 weeks, can meet the requirements. However, the effective temperature and heating time for low temperature response vary greatly depending on the variety.
Deep Wave Leaf Blood Grass is a short-day plant, and long-day treatment can promote blooming. Additionally, spraying once with gibberellin (500×10^-6) before bolting can also advance flowering. In cultivation, other varieties of the Limonium genus are also mainly propagated by sowing. Some cold-sensitive varieties are sown in protected areas in autumn and bloom in the early summer of the second year; cold-tolerant varieties are usually cultivated as perennials, and they bloom in the second year after spring sowing, but Blood Grass can bloom in the autumn of the same year after spring sowing. Since Blood Grass is a plant with a direct root system, transplantation is quite difficult, so it must be transplanted with soil during the seedling stage to improve survival rates. In addition to sowing, Blood Grass can also be propagated by cutting.
