Muhlenbergia sp. mexico
Giant Deer Grass
Description
Muhlenbergia species mexico is best described as our native Deer Grass, Muhlenbergia rigens, on steroids. We've never managed to get it horticulturally keyed but perhaps this will be the year we get to the bottom of its heritage. The giant Muhly is one of the tallest native southwestern grasses we've ever encountered. For its size, it's actually quite tidy, with good looking foliage year-round, but since it's a big grass, give it room.
Giant Deer Grass is great as a background grass and for screening with ample water. It works well in groups with other tall meadow flowers like Helianthus, Boltonias, and Verbena bonariensis. Great either by the sea or in desert gardens. Although it tolerates the heat of the desert, it will need plenty of water there to really thrive. Use it on slopes or in bioswales, as it can handle seasonal moisture.
Our plants came from famous SoCal plantsman Gary Hammer, who sadly is no longer with us. We don't know where in Mexico he collected it, but we will continue to grow it because it's a great though underused grass. Gary gave us so many great plants... we miss you, man.
