Artemisia arbuscula Nutt. ssp. nova (A. Nels.) G.H. Ward, commonly known as Little sagebrush, is a shrub that belongs to the sunflower family (Asteraceae). The plant is native to North America and can grow up to 60 cm tall. Little sagebrush is mostly propagated through seeds, cuttings, and division.
Propagation by Seeds
The most common method of propagating Artemisia arbuscula is through seeds. The seeds are collected from mature plants and sown in seed trays or containers. Sowing can be done in spring or fall, and the containers should be placed in a sunny area. Germination usually occurs within two to three weeks. Once the seedlings are established, they can be transplanted into pots or a well-prepared garden bed.
Propagation by Cuttings
Artemisia arbuscula can also be propagated through stem cuttings taken from mature plants. The best time to take cuttings is in late spring or early summer when the plant is actively growing. Cuttings should be taken from the tips of the stems, and the leaves should be removed from the lower half of the stem. The cuttings should be dipped in rooting hormone and placed in a well-draining potting mix. The pot should be placed in a warm, humid area, and the soil should be kept moist until the cuttings have rooted. The rooted cuttings can then be transplanted to larger containers or the garden bed.
Propagation by Division
Little sagebrush can also be propagated through division. This method involves dividing the plant into smaller sections and replanting them. The best time to divide the plant is in the early spring before new growth begins. To divide the plant, carefully lift it from the soil and separate the root system into smaller sections. Each section should have some healthy shoots and roots. The divided sections can be planted immediately in a well-prepared garden bed or pots.
