Propagation of Panicum barbipulvinatum Nash
Panicum barbipulvinatum Nash, commonly known as velvet panic grass, can be propagated by seeds or vegetative methods such as stem cuttings and division of clumps.
Propagation by Seeds
The seeds of Panicum barbipulvinatum Nash can be directly sown outdoors in the spring after the last frost. It is recommended to scarify the seeds by nicking them with a blade or rubbing them with sandpaper to break their tough outer layer and improve germination rates. The seeds should be planted at a depth of ¼ to ½ inch and spaced 6 to 12 inches apart. They should be watered regularly to keep the soil moist until germination, which usually occurs within 14 to 21 days.
Vegetative Propagation
Stem cuttings can be taken from Panicum barbipulvinatum Nash in the spring or early summer. The cuttings should be about 6 inches long and taken from the base of the plant or from new growth. The lower leaves should be removed, and the cutting should be planted in a pot filled with a well-draining potting mix. The cutting should be watered regularly and kept in a warm, bright location until roots develop, which usually takes 4 to 6 weeks.
Division of clumps is another method of propagating Panicum barbipulvinatum Nash. This should be done in the spring, before new growth emerges. The clumps should be carefully dug up and divided into sections, ensuring that each section has a good root system. The sections can then be replanted in a sunny, well-draining location and watered regularly.
Regardless of the propagation method used, Panicum barbipulvinatum Nash generally grows well in full sun or partial shade and prefers well-drained soil.
