Propagation of Argemone munita Dur. & Hilg. ssp. rotundata (Rydb.) G.B. Ownbey
Argemone munita Dur. & Hilg. ssp. rotundata (Rydb.) G.B. Ownbey, commonly known as the prickly poppy or yellow thistle, is a hardy, drought-resistant plant that is a member of the poppy family. It is commonly found in rocky and arid regions of western North America, including the Great Basin, Mojave Desert, and Sonoran Desert. The plant is known for its large, showy yellow flowers and spiny leaves and stems. Propagation of Argemone munita can be done through different methods, including seed propagation, stem cuttings, and division.
Seed Propagation
Argemone munita can be easily propagated from seeds collected from mature plants. The seeds are small, black, and hard, and can be sown directly in the ground during the early spring after the last frost. The soil should be well-drained, and the seeds should be planted at a depth of about 1/4 inch. Germination may take up to two weeks. Once the seedlings have grown two to three true leaves, they can be transplanted to the desired location.
Stem Cuttings
Another way to propagate Argemone munita is through stem cuttings. This method is best done during the early spring when the plant is actively growing. Cut a 4-5 inch long stem from a mature plant, making sure that it has at least two nodes. Remove the leaves from the bottom half of the stem, leaving only the top leaves. Dip the cut end of the stem in rooting hormone and plant it in a well-draining soil mixture. Keep the soil moist and the cutting in indirect sunlight until roots develop, usually after 4-6 weeks.
Division
Argemone munita can also be propagated through division. This method is best done during the early spring, when the plant is actively growing. Carefully dig up the plant, being sure to keep as many roots intact as possible. Gently separate the plant into several sections, making sure each section has enough stems and roots to survive. Replant the sections in a well-draining soil mixture, keeping the soil moist until they become established.
Disease and Pest Management for Argemone munita Dur. & Hilg. ssp. rotundata (Rydb.) G.B. Ownbey
