Nolina parryi is the giant nolina of California — one of the largest and showiest species in the genus, forming massive rosettes of up to 220 stiff, bluish-green leaves atop a stout trunk that can reach 60 cm in diameter. Native to the chaparral, coastal sage scrub and desert mountains of southern California, Arizona and Baja California, it is the iconic beargrass of Joshua Tree National Park and the Peninsular Ranges. Named after Dr. C.C. Parry, who first collected it near Mount San Jacinto, it is an outstanding architectural plant for Mediterranean and warm-temperate gardens.
Taxonomy and nomenclature
Family Asparagaceae, subfamily Nolinoideae. The species has a complex synonymy: Nolina wolfii and Nolina parryi subsp. wolfii are sometimes recognised as distinct but are typically included within the species. Nolina parryi has also been treated as a subspecies of Nolina bigelovii (Nolina bigelovii subsp. parryi), but the current consensus treats them as separate species. Plant Delights Nursery notes that it “resembles Nolina bigelovii, but with more minutely serrated leaf margins.”
Common names
Parry’s beargrass, Parry’s nolina, giant nolina (English).
Morphological description
Habit
A large, multi-stemmed, evergreen shrub to small tree. Mature plants can exceed 2 m (6.5 ft) in height, with flower stalks reaching 4 m (13 ft). The trunk is stout, up to 60 cm (24 in.) in diameter, rough-barked and branching a few times from the base to create small but tightly packed colonies. Roger’s Gardens describes a mature canopy reaching 1.8 m (6 ft) tall and 1.8 m (6 ft) wide, with flower height to 3.7 m (12 ft).
Leaves
Dense rosettes of 65–220 stiff, linear leaves, each 50–140 cm (20–55 in.) long and 2–4 cm (1–1.5 in.) broad. Bluish-green, sword-like, finely serrated margins. Somewhat flexible and not sharply pointed — less dangerous than Dasylirion but still commanding respect. Plant Delights describes the foliage as “3/4 in. wide × 36 in. long, non-spiny, yucca-like evergreen.”
Inflorescence and flowering
A spectacular plume-like inflorescence emerging in late spring (April–June), bearing fragrant white flowers, up to 4 m tall. One of the most impressive flowering events in the nolinoid world. Dioecious. The spent flower stalk persists and adds structural interest. Native Americans consumed the young stems and wove the leaves into baskets.
Distribution and natural habitat
Native to southern California (Peninsular Ranges, San Bernardino Mountains, Kern Plateau of the high Sierra Nevada), western Arizona and Baja California. Found on dry slopes, ridges, chaparral, coastal sage scrub, pinyon-juniper woodland and Joshua Tree woodland, at elevations of 900–2,100 m (3,000–6,900 ft).
Cultivation guide
| Hardiness | −10 to −12 °C / 10–14 °F (USDA zone 8a) |
| Light | Full sun |
| Soil | Very well-drained; rocky; any pH |
| Water | Very low; xeric |
| Growth rate | Slow (60+ year lifespan) |
| Flowering | April–June; spectacular plume to 4 m |
Light requirements
Full sun without exception. This is a plant of exposed ridges and dry slopes.
Soil and drainage
Very well-drained. Rocky, infertile soil is preferred. Tolerant of a wide pH range. Roger’s Gardens notes it “prefers dry to average moisture levels with very well-drained soil, and will often die in standing water.”
Watering
Extremely drought-tolerant. No supplementary water once established. An ideal xeriscaping and water-saving plant.
Cold hardiness
Hardy to approximately −10 to −12 °C (10–14 °F). Roger’s Gardens rates it as zone 8a. This makes it intermediate between the ultra-hardy stemless species and the tender desert species. In European gardens, it is well-suited to Mediterranean, coastal and warm-oceanic climates.
| USDA zone | Growing mode | Notes |
|---|---|---|
| 9–11 | In-ground, no issues | Core climate |
| 8a–8b | In-ground | Well-drained position; some protection for young plants |
| 7b and below | Container or borderline in-ground | Protection needed; raised bed with rain shelter |
Landscape use
A magnificent focal accent. The broad, dense rosettes, stout branching trunk and towering plume-like inflorescences make Nolina parryi an outstanding specimen plant in Mediterranean landscapes, gravel gardens, dry borders, xeric plantings and native California gardens. Excellent poolside or in large containers. Deer-resistant. Roger’s Gardens recommends it for “mass plantings, accent, and general garden use.”
Propagation
Seed: sow in cold frame or greenhouse in late winter. Cool-weather germination.
Offsets: individual offsets from mature plants can be taken in winter.
Pests and diseases
Root rot in waterlogged soil. No significant pest problems. Deer-resistant. Verticillium wilt resistant.
