Nolina interrata (Dehesa Bear Grass) - Dehesa bear grass occurs in localized populations from the interior foothills of San Diego County to northwestern Baja California, Mexico. Most populations of N. interrata are situated in relatively rugged terrain dominated by chaparral, which is often associated with nutrient-poor soils, cool wet winters and hot dry summers. Nolina interrata does not flower every year and reproduces primarily asexually from underground stems. However, fires and other disturbances will induce profuse blooming and timed controlled burns may be necessary to maintain population vigor. A total of about 9,000 Nolina interrata plants are known. Occurrences that are entirely female require pollen from disjunct male plants to fertilize the flowers and produce viable seeds. Nolina interrata is cultivated at the Huntingdon Desert Garden, where it flowers annually.
This information about Nolina interrata displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
