Pennisetum alopecuroides- The Infertile Collection

Posted by Emerald Coast Growers on May 8th 2025

These ornamental grasses are specifically bred to be infertile and remove concerns about localized self-sowing. In addition, they also offer vigorous growth and gorgeous extended color from summer to fall. Many of the genera chosen provide strengths that breeding, in turn, enhances.

Temperature: Keep greenhouses at 70 to 80° F during the day and 55 to 65° F at night.

pH & EC: Aim for pH at approximately 5.8 to 6.2 and electrical conductivity (EC) at 1.0 to 1.5 mS/cm using the 2:1 extraction method.

Light: Provide full sun or at least 5,000 footcandles, along with at least 12 hours of photoperiod supplemental lighting.

Fertilizer: Fertilize with a constant liquid feed of a balanced fertilizer at low levels of 100 to 150 ppm nitrogen.

Water: Allow plants to dry between ample waterings.

Day length: Long day
