Spiny Rush, also known as Sharp-Pointed Rush, is a large, striking plant with a bold architectural form. Its sharp, spiny-ended stems give it a dramatic look, but it’s best planted away from walkways due to its pointed stems. It works well in dry streambed plantings or as a specimen plant alongside other large native species.

Spiny Rush thrives in various soil types, from those that experience extremes of flooding and drying, such as dunes or washes, to areas that remain consistently wet. It also tolerates heavy clay soils and saline conditions, making it a versatile choice for difficult landscapes. In addition to its ornamental use in gardens and wildflower meadows, it helps reduce soil erosion.

Traditionally, Spiny Rush has been used as a source of fiber for making paper, baskets, and other woven goods, as well as for medicinal purposes. As a riparian plant, it provides important habitat and food for wetland wildlife, including insects, birds, and mammals. Additionally, it plays a vital role in wetland ecosystems by helping prevent soil erosion and maintaining water quality, producing a compound that inhibits algae growth.

Growing Plants in the Desert — Important Information

The information presented here is, to the best of my knowledge, accurate and based on my research from reliable sources, observations I have made of plants growing in my, and other gardens I have visited, and observations of the plants in their native habitats. I would appreciate your feedback and experience to help me educate others!

Cacti: In my experience, cacti are much happier in the filtered shade here in the low desert of the Coachella Valley. Colors are more vibrant and they bloom more profusely, especially the non-native varieties. If you pay attention to how our native barrel and beavertail opuntia grow in the wild, it is frequently tucked in the rocks under creosote or another shrub.

Light Requirements: I have found that in our desert (Sonoran/Colorado) “full sun” plants can take and appreciate the late afternoon filtered sun, especially in the hot summer months.
