Sergio Niebla (sergioniebla@Flickr) took this photograph of two plants of Nolina nelsonii plants (with Agave americana on the right) in La Reforma, Tamaulipas, Mexico. Thank you, Sergio! This species is native only to the state of Tamaulipas, though it is also cultivated, especially in Texas.
Blue nolina or Nelson’s bear grass goes by the scientific name Nolina nelsonii. Its physical appearance is often compared to species of Yucca, another genus in Asparagaceae. Nolina nelsonii leaves are narrow and long, up to about 80 cm in length, with miniscule teeth lining their margins. Plants resemble a small trees, with a head of the rigid, blue-green leaves sitting atop a 1-3.7m tall trunk. The inflorescence that protrudes from the foliage can measure 2-3.4m in length, adding to the plant’s already unusual appearance.
Nolina nelsonii prefers well-drained soils and sunny environments. Not only is it drought tolerant, but it can also survive freezing temperatures down to -12°C. (Irish & Irish’s Agaves, Yuccas, and Related Plants (2000))
