Nolina erumpens is the foothill beargrass of the Trans-Pecos — an enormous, mounding nolina that can reach 2.4 m (8 ft) tall and wide, making it one of the largest acaulescent species in the genus. Found in the brushlands and rocky arroyos of west Texas (Big Bend country) and adjacent Chihuahua, it produces dark cream flower spikes up to 2.4 m (8 ft) tall, often only barely emerging from the massive foliage mound. Rare in cultivation, it is a plant for specialists — but its cultural history is as deep as any in the genus.
Taxonomy and nomenclature
Family Asparagaceae, subfamily Nolinoideae. POWO: Mexico (Chihuahua) and the United States (western Texas, Hudspeth to Terrell Counties).
Common names
Foothill beargrass, foothill nolina, sand beargrass, basket grass (English).
Morphological description
Large clumps of coarse, yucca-like leaves growing from woody basal stems. Flower stalks 1.2–2.4 m (4–8 ft) tall, partially or entirely enclosed within the foliage, bearing flowers described as “a large, rosy cluster” — unusually coloured for a nolina. Spadefoot Nursery describes the flowers as occurring on “comparatively broad bloom spikes that may only just barely emerge from the foliage.”
Distribution and natural habitat
Brushland arroyos and rocky places in the Trans-Pecos region of Texas, on limestone or clayey, rocky soils. Part of the Chihuahuan Desert flora, growing alongside Agave havardiana, Yucca faxoniana and other classic Big Bend species.
Cultivation
Hardy to approximately −18 °C (0 °F) according to Spadefoot Nursery. Full to part sun, low water (supplement once or twice monthly in summer). Can get too big and aggressive for small sites. Rarely seen in cultivation outside botanical gardens.
Ethnobotany
One of the most extensively documented nolinas ethnobotanically. The stalks were eaten; seeds were ground into flour for bread or mush; fruit was eaten raw or preserved. The roots were used as soap (a use documented as late as the 1940s on the Fort Apache Reservation). Leaves were used for basketry, rugs, mats, weaving, brushes, rope, cordage and cooking tools. Archaeological evidence of beargrass basketry from Hinds Cave spans at least 8,000 years. The species is also a larval host for the Grey Hairstreak butterfly (Strymon melinus).
