Andropogon glomeratus
Bushy Bluestem
Andropogon glomeratus
Andropogon glomeratus, commonly known as bushybeard, is a perennial bunchgrass native to the Americas. It features erect stems that can reach heights of 1 to 4 feet, with narrow, bluish-green leaves. The inflorescence is a dense, purplish-brown panicle. It's known for its tolerance of drought and poor soils, making it a suitable choice for landscaping in challenging conditions. It's also important to note that it can be somewhat aggressive in its spread, particularly in favorable conditions.

Liatris spicata
Blazing star complements bushybeard's height and texture, creating visual interest in a prairie-style planting. Both plants prefer full sun and well-drained soil.

Schizachyrium scoparium
Little Bluestem is another native bunchgrass that thrives in similar conditions to bushybeard. Planting them together creates a dense, natural look, mimicking native grasslands.
Sorghum halepense
Johnson grass
Sorghum halepense

Johnson grass is a vigorous, invasive weed that aggressively competes for resources. Its rapid growth will overshadow and outcompete bushybeard for water and nutrients.

Grasshoppers

Grasshoppers can cause significant damage to the foliage, leaving behind ragged edges and holes. Heavy infestations can severely weaken the plant.

Armyworms

Armyworms are caterpillars that feed on the leaves, causing defoliation. They can quickly decimate a stand of bushybeard if not controlled.

Steps:

    • Carefully dig up a mature clump of bushybeard in early spring or fall.
    • Separate the clump into smaller divisions, ensuring each has healthy roots and shoots.
    • Replant the divisions in well-prepared soil, spacing them appropriately.
    • Water thoroughly after planting.

Neem oil

Effective natural insecticide for controlling grasshoppers and other chewing insects.

Bacillus thuringiensis (Bt)

A biological insecticide that targets armyworms and other caterpillars.
