Lindheimer’s muhly

Muhlenbergia lindheimeri

Description

Lindheimer’s muhly is a soft textured species with narrow semi-evergreen leaves that are medium green in color and provide a soft and relaxed character in garden settings. It is native to Texas and Mexico and, like other muhly grasses, has proven to be highly adaptable to garden conditions. Foliage grows 2-3 ft. tall; flower panicles can reach 5 ft. high.

Lindheimer’s muhly is a large clumping species distinguished by its green leaves and soft texture. Foliage and flower panicles fade to pale green and blond colors in late fall; cut back to the base in late fall through early winter to prepare for the upcoming spring growth cycle. A good border plant, in parkways and on banks and slopes to contrast with flowering perennials and shrubs.

Watering Schedule: Medium

For most situations, we recommend watering once per week after establishment, watering very deeply in summer, less deeply in fall and spring, and even less in winter.

See our recommendations for how much water to apply each time you water, below. Note that these recommendations are intended for inland valley areas of Southern California including the Inland Empire, San Gabriel, and San Fernando Valleys. People in cooler or warmer areas may use this as a baseline but should adjust based on local needs.

Seasonal Watering Recommendations

June – August: once per week, water deeply, applying approximately 1.25” of irrigation.
September – October: once per week, water deeply, applying approximately 0.75” of irrigation.
November – February: once per week, water deeply, applying approximately 0.5” of irrigation.
March-May: once per week, water deeply, applying approximately 0.75” of irrigation.

Adjusting to your local needs

These recommendations for Medium / Moderate water demanding plants were created for Southern California inland valley areas. Southern California areas closer to the coast and along the coast will usually be able to water significantly less during the warm months of the year. For desert areas, check with local experts to be sure plants are appropriate for the area and anticipate needing to water more.

As a very general baseline, people in Los Angeles and similar areas can try setting a schedule of 80% of the in Spring, Summer, and Fall and adjust as necessary based on observation. The difference is less pronounced in the winter months, so we recommend starting with the same recommendations as above for winter. People in cooler coastal areas such as Santa Monica can try using this same approach but adjust to use 75% of the chart recommended minutes for the Spring, Summer, and Fall months.

Important Notes

These are general guidelines. Always observe and adjust as necessary for your landscape.
If it rains over 1” you will likely not need to water for at least another week, possibly longer. Before watering again, check the soil. It should be significantly dry at least 4” below the soil surface before watering again.
It is important to group plants with the same water needs together in the landscape to avoid needing to over or under water plants when running your irrigation system.
“Smart timers” or weather sensitive irrigation controllers such as Rachio and Hunter Hydrawise are ideal for watering plants in this category because they will automatically adjust how much they water based on the weather so you do not need to reprogram the timer seasonally. Rebates for these types of irrigation controllers are available through socalwatersmart.com.

In late winter or early spring, just prior to spring growth, cut back hard, to an appx. 6″-1′ mound. For multiple plants, this is best done using a manual or powered hedge trimmer. If needed, dried flowers can be cleaned up over the winter with a very light shearing, but it is a warm season growing grass so avoid cutting back significantly during the cool season. If you only have a few plants, old flower stalks can be removed individually with a hand pruner. After the pink flowers fade to tan, the dried flowers continue to look attractive for quite some time. Consider waiting to remove dried flowers until they begin to look unattractive (S). References
