Dallas Blues Switch Grass (Panicum virgatum 'Dallas Blues')

Pollination Information:

Dallas Blues Switch Grass is a perennial grass that readily produces seeds through cross-pollination by wind. It is a dioecious plant, meaning it has separate male and female flowers on different plants. Therefore, both male and female plants are required for successful pollination and seed production.

The flowers of Dallas Blues Switch Grass are borne on airy, open panicles that rise above the foliage. The male flowers, located on one plant, produce pollen. The wind carries the pollen to the female flowers, which are located on a separate plant. The wind-pollinated female flowers then receive the pollen and develop seeds.

As wind is the primary pollinator of Dallas Blues Switch Grass, it is essential to plant multiple individuals of this grass in proximity to encourage successful cross-pollination. Planting at least one male plant for every five female plants is generally recommended to ensure an adequate pollen supply for pollination. This ensures the production of viable seeds and promotes genetic diversity within the population.

While Dallas Blues Switch Grass does not require active human intervention for pollination, providing a suitable environment that allows wind to carry the pollen effectively is important. Planting this grass in open areas with good air circulation will facilitate the pollination process.
