Pollination Information for Shenandoah Switch Grass (Panicum virgatum 'Shenandoah')

Shenandoah switch grass, like other panicum virgatum cultivars, is a wind-pollinated perennial grass. It does not rely on insect pollinators to reproduce and set seed.

The flowers of Shenandoah switch grass are small and inconspicuous, and they are arranged in panicles that emerge from the stem in late summer through fall. The panicles contain both male and female flowers that produce pollen and ovules, respectively. When the wind blows, pollen is dispersed from the male flowers to the female flowers, resulting in fertilization and seed production.

It is important to note that because Shenandoah switch grass is wind-pollinated, it can contribute to allergic reactions in some individuals who are sensitive to grass pollen. However, it is not considered a major allergen like some other grass species.

When does Shenandoah switch grass bloom?

Shenandoah switch grass blooms in late summer to early fall. It produces feathery, pinkish-red flowers that rise above the foliage.

How often should Shenandoah switch grass be fertilized?

How do I prune Shenandoah switch grass?

Shenandoah switch grass does not require regular pruning. In late winter or early spring, you can cut back the dead foliage to make way for new growth. If the plant becomes too tall and starts to flop over, you can cut it back by about one-third in early summer to promote bushier growth.

Is Shenandoah switch grass deer-resistant?

Shenandoah switch grass is generally considered deer-resistant, as deer tend to avoid plants with tough, fibrous foliage like switch grass. However, if deer are particularly hungry or there is a shortage of other food sources, they may still nibble on the foliage.
