Chaparral yucca may also occur with bigcone Douglas-fir (Pseudotsuga macrocarpa) at elevations of 900 to 3,500 feet (270-1,100 m) in southern coastal California [74] and on steep south-facing slopes in the Santa Ana Mountains [9]. Coastal sage scrub: For more on vegetative regeneration following fire, see After 5-10 years, once the plant reaches maturity, it will shoot up a 10-15 ft tall, glorious flower spike! The researcher suggested that after a minimum of 7 years, a fraction of a chaparral yucca cohort reached reproductive maturity [124]. forms Species common to the desert woodlands included Joshua tree (Yucca brevifolia) and California juniper (J. californica). Seed production: In the Liebre Mountains, chaparral yucca was considered widespread and occurred in grassland, scrub, and woodland vegetation [11]. Hesperoyucca whipplei - Chaparral yucca SEARCH for plants. Researchers found 34 germinated seeds in 23 fruits attached to the inflorescence and 16 germinated seeds in 16 unattached fruits in leaf litter. Severity of the summer fire was not described [29]. This information is taken from the glaber) [35]. Yucca newberryi McKelvey, solitary monocarpic rosette [54]. Yucca moths, other insects, and mule deer may reduce chaparral yucca flower and seed production. Cross vs. self-pollination: Newberry's yucca is restricted to the vicinity of the Colorado River in the lower Grand Canyon in Mohave County, Arizona [23,113]. The Flora of North America [23] indicates that chaparral yucca occurs in southern California, and Newberry's yucca occurs in western This is a very showy yucca, especially if seen in masses on a hillside while in full bloom. Pollination by yucca moths: In annual grasslands and coastal sage scrub, fire probability was strongly correlated with high precipitation levels the previous winter. Others have also suggested a link between moisture and seed production. Occurs up to 8,00 feet in desert, chaparral, and coastal shrub communities (Munz 2004,p.31). Tetrazolium chloride tests indicated that the viability of chaparral yucca seed collected from native habitats was 50% to 100%. Chaparral yucca may be most abundant in chamise chaparral on ridgetops and steep south-facing slopes where overall plant cover is sparse [70,115]. Yucca whipplei ), the chaparral yucca, our Lord's candle, Spanish bayonet, Quixote yucca or foothill yucca, is a species of flowering plant closely related to, and formerly usually included in, the genus Yucca. Yucca root is a natural saponin (meaning it suds) used by native Americans for centures to gently cleanse hair and fine woolens. Viability of chaparral yucca seeds is generally high, but germination can be highly variable. caespitose Woodlands and forests: are lacking, sprouts may develop from the caudex, short basal stems, and/or rhizomes. Chaparral yucca was dominant in desert chaparral in the inner South Coast Ranges and on the lower slopes of San Gabriel, San Bernardino, San Jacinto, Santa Rosa, and Laguna mountains. This is the largest form of the species, hailing from the front side of the San Gabriel Mountains in La Canada in the Los Angeles area, from about the 3000' elevation. In California, chaparral yucca is most common from sea level to 4,500 feet (1,400 m) [83,117] but occasionally occurs at elevations up to 8,200 feet (2,500 m) [22,32,42,83,117]. Chaparral Yucca (Hesperoyucca whipplei) AGAVACEAE . One of the things I associate with June in Southern California is the presence of flowering Yucca stalks dotting the slopes of the nearby mountains and hillsides. Caespitose and rhizomatous forms can support 3 to 200 rosettes, and rhizomes can connect rosettes 3 to 10 feet (1-3 m) apart [45]. In the Santa Ynez Mountains near Santa Barbara, density of chaparral yucca was much greater on burned sites where fire burned in a fuelbreak where vegetation was cleared before burning (70 plants/900 m²) than in burned chaparral with standing vegetation at the time of fire (20 plants/900 m²). Please try your search again later. When chaparral yucca fruit set was compared in 18 southern California populations, average fruit production was least for populations in xeric desert scrub, intermediate in coastal sage scrub, and greatest in relatively mesic chaparral communities. Fire adaptations and View picture of Hesperoyucca Species, Chaparral Yucca, Our Lord's Candle, Quixote Yucca (Hesperoyucca whipplei) at Dave's Garden. In California, small flies, bees, and beetles were observed gathering nectar from the base of chaparral yucca flowers, but none of these insects touched anthers or stigmas [108]. In southern California, the population averages for flowering stalk height ranged from 5.9 to 17.4 feet (1.7-5.3 m), and panicle length ranged from 2.5 to 9.3 feet (0.8-2.8 m) [31]. Sow seed in spring or summer, in pots containing Cactus mix. Chaparral yucca and Newberry's yucca are native to North America and occur in many disjunct populations in northern Baja California, southern California, and/or northwestern Arizona [99]. SOURCES. Whole or split yucca leaves were also utilized for rough tying of bundles of firewood, house frames, and for basketry. Greenhouse experiments suggest that chaparral yucca may produce more roots in arid conditions. In the following year, brush was added to an adjacent site and burned in a prescribed fire in February. habitats [22], but additional information about chaparral yucca habitats in Baja California was lacking as of 2012. Cancer 4. Seed produced by self-pollinated flowers is less likely to result in successful reproduction than seed produced by cross-pollinated flowers. Chaparral yucca seed capsules mature after about 140 days, in late spring and summer [18,91]. Our local female yucca moth is … Additional studies of habitat and plant community relationships of Newberry's yucca were lacking. It has been described in California juniper-blue oak cismontane woodlands on rocky outcrops [44], gray pine (Pinus sabiniana)-blue oak (Q. douglasii) woodlands on well-drained mediterranean sites in the Central Valley [44], and singleleaf pinyon (P. monophylla)-California juniper woodlands in the desert foothills of the San Gabriel Mountains [34]. Details of yucca pollination in San Diego County are described in a fascinating article by George Cox (Environment Southwest No. Yucca moth larvae generally consume 6 to 14 seeds within a fruit [3,18], yet a "fair percentage of the seeds are allowed to come to maturity" [108]. In his 1893 study of chaparral yucca, Trelease [108] indicated that a caespitose form of about 8 to 10 crowns clustered around a single root system was most typical. We have outdoor seeds and indoor varieties. woodlands [22,31,117]. In the Transverse and Coast ranges of southern California, chaparral yucca occurs with desert chaparral vegetation dominated by a mixture of chamise, red shank (Adenostoma sparsifolium), manzanita (Arctostaphylos spp. Elevation: The percentage of seeds from these lots that developed into seedlings in the greenhouse ranged from 0% to 100% [6]. Seeds: Plant the seeds in the fall in deep, one-gallon pots in well-drained soil. From 1985 to 2001, there were 12 to 32 lightning strikes/100 km²/year; most lightning strikes occurred from July through September. Please try again.

Riversidean sage scrub vegetation is generally open and dominated by California sagebrush, eastern Mojave buckwheat (Eriogonum fasciculatum), and red brome (Bromus rubens). It is native to southern California, United States and Baja California, Mexico, where it occurs mainly in chaparral, coastal sage scrub, and oak woodland plant communities at altitudes of 0–2500 m. The moth that pollinates Yucca whipplei in the chaparral of San Diego County is Tegeticula maculata. Although the likelihood of sprouting or seedling establishment may be reduced when fires are severe, large increases or decreases in chaparral yucca abundance following fire are rare. Along the coastal bases of the Transverse and Peninsular ranges in southern California, chaparral yucca is characteristic of Riversidean sage scrub, which occupies xeric sites that may be steep, severely drained, and/or have clay soils with very slow moisture release. Occurs up to 8,00 feet in desert, chaparral, and coastal shrub communities (Munz 2004,p.31). Chaparral yucca occurred on unburned transects but was rare on burned transects [103]. Sends up a large spike with profuse, fragrant flowers at end of life (5-10 years). Although studies distinguishing the origin of sprouts from various chaparral yucca Cells are blank where information is not available in the Rapid Assessment Vegetation Model.

NEWS - FEATURES: None of the links on this page are sponsored. In some studies, chaparral yucca was rare or absent from burned sites. For most of its life, the Chaparral Yucca is a striking, pointy mound of 3 ft silver-green spikey leaves. Caespitose forms dominated populations at the western margin of Mojave Desert from the San Bernardino Mountains to the Tehachapi Pass and the Piute and Greenhorn mountains. However, northern and coastal rhizomatous populations lost up to 25% of their seeds to larvae, and the number of capsules without larvae was substantially greater for monocarpic than caespitose or rhizomatous forms [61]. Find further fire regime information for the plant communities in which these Less seed is produced by self-pollinated than cross-pollinated flowers. were lower for seeds produced through self-pollination.

In a study conducted to determine the effects of seed predation on banana yucca, 10% to 12% of seeds were lost to moth larvae. Good accent plant in dry garden. Weight loss Some early research points to potential support for some (but not all) of these uses, but the… These ecosystems occupy sites with mediterranean climates, where winters are cool and wet, and summers are hot and dry [66]. SESSION. Seeds germinated 9 days after sowing and required no pretreatments [81]. Currently unavailable. One of the things I associate with June in Southern California is the presence of flowering Yucca stalks dotting the slopes of the nearby mountains and hillsides. In the Sierra San Pedro Mártir, Baja California, the fire-return interval in chaparral is usually 40 to 50 years. Common Name: Chaparral Yucca or Our Lord's Candle. The shame is, the plants die after flowering. When adjacent stands of coastal sage scrub and bigpod ceanothus chaparral were compared in the Santa Monica Mountains, chaparral yucca cover and density were greater in coastal sage scrub [26,27]. Relative humidity is low in the summer (10%-30% in July), when fire spread is likely in the southeastern desert bioregion. Leaves are flat, rigid, gray-green in color, and have minutely serrate margins and sharp terminal spines about 0.4 to 0.8 inch (1-2 cm) long [15,42,83].

This table summarizes fire regime characteristics for each plant community listed. No flowers were observed in the prefire spring flowering season. See the Chaparral yucca infrataxa are no longer recognized [23,104]. They typically split in mid-August, and seeds are dispersed in gusty winds [18]. The young flowers are edible but bitter. germination Chaparral vegetation burned after wet and dry years. Then once the caterpillars hatch, they eat the seeds. and are generally distinguished by differing growth forms. Sprouting of chaparral yucca is considered common after fires that are not severe [12,15,118]. The stalk and roots can be eaten when prepared properly. Haines [31] found chaparral yucca in the Upper Sonoran and Transition Life Zones with coastal sage scrub communities, chaparral vegetation, pine woodlands, and desert woodlands. We will offer subspecies percussa in the next few weeks, which is a dwarf form that produces more than one rosette of leaves - only the rosette that flowers dies, leaving a slowly growing clump of rosettes. Newberry's yucca grows only as a monocarpic, solitary rosette. There are also chaparral yucca forms with both rhizomatous and caespitose characteristics [117]. Camp Elliot Chaparral Reserve looking NW at Scripps Ranch. The genus Hesperoyucca (Agavaceae) in the western United States and Mexico: New nomenclatural combinations. Predation by yucca moth larvae, other insects, and mule deer can reduce seed production. It was absent from the most mesic sites and had low cover on sites with high exchangeable ammonium concentrations in the soil [121]. Chaparral yucca is a perennial that grows 8-10 feet from a dense basal rosette of stiff, strap-shaped, gray-green leaves. On the coastal side, chaparral yucca cover averaged 0.4% on sites burned 2 to 8 years prior and 0.6% on sites burned 41 to 96 years prior.

In chaparral vegetation, however, the size of individual fires was much greater in southern California than in northern Baja California. Fire intervals can be as short as 20 years for both types. Moths deposited their eggs before pollinating chaparral yucca flowers. [20]. Seeds from monocarpic plants germinated after 5 days, and those from caespitose plants germinated after 8 days. Chamise chaparral generally occurs on hot, dry, south- and west-facing slopes with sandy, rocky soils that lack nutrients and horizon development [37]. In a horticultural study, 1-year-old chaparral yucca seedlings from seed collected in the Santa Ana Mountains were transplanted into a common garden. When adjacent stands of coastal sage scrub and bigpod ceanothus (Ceanothus megacarpus) chaparral were compared in the Santa Monica Mountains, chaparral yucca density averaged 0.01/m² in chaparral and 0.07/m² in coastal sage scrub communities. In early postfire succession (1-2 years after fire), chaparral yucca sprouts were often reported without seedlings, but not all plants survived fire. An experiment with strictly monocarpic chaparral yucca forms at the Sonoran Desert margin in Riverside County found no fruit production from 618 bagged flowers, while 886 unbagged flowers produced 75 fruits [2]. Pollinator abundance was not correlated with fruit set; on sites with an excess of pollinators, fruit set remained low [111]. Cover of chaparral yucca was not very different in chaparral sites burned 2 to 96 years prior. germination and The moth places the pollen on the stigma and lays her eggs there. Chaparral Yucca - [Spanish Bayonet, Quixote Yucca, Foothill Yucca, Our Lord's Candle; Hesperoyucca whipplei] Hesperoyucca were recently broken off from Yucca due to some morphological differences. See this Fire Study in FEIS for further information on responses of In midelevation sites in cismontane southern California, researchers found no major shifts in life form or species composition in chaparral burned 0 to 8 times from 1910 to 2001 [25]. After 3 years of storage at 40 °F (4 °C), 75 % of seeds germinated . While the chaparral plant is not proven to be totally safe and effective, in traditional folk medicine and alternative medicine, it has been used for a host of things, such as: 1. Therefore, mortality may have been overestimated if some plants had flowered and died prior to the fire. Prime members enjoy FREE Delivery and exclusive access to music, movies, TV shows, original audio series, and Kindle books. Survival of seedlings from self-pollinated seeds was 71% of that from cross-pollinated seeds. Seed production can vary by plant size, growth form, site and climatic conditions, and pollination method. Most often found on stoney slopes in chaparral in Southern CA and in Baja CA. They are about one inch (2.5 cm.) long and have a hard, dry husk. Field observations and experiments indicate that successful pollination of chaparral yucca flowers is unlikely without yucca moths [17]. Fire frequency did not vary between chaparral and coastal sage scrub from 1930 to 1978 in the western Santa Monica Mountains. Often the species present in the first postfire year are also present in mature communities [25,33,36]. 10459 Tuxford Street Sun Valley, California 91352 818-768-1802. On 1-year-old burned sites on the Angeles National Forest, chaparral yucca mortality averaged 50%. The number of larvae/capsule was negatively correlated with elevation, distance from the coast, total annual precipitation, and average temperature (P<0.05). While any chaparral yucca population is usually a mixture of 2 or 3 growth forms [45], some studies report dominance of particular forms related to distribution and habitat; for more information, see Lay the seeds on top of the soil and sprinkle soil over the seeds until they are covered. A review reports that the "normal" fire-return interval in coastal sage scrub is 30 years [4]. Growth forms: Chaparral yucca is a perennial, acaulescent plant that grows from a caudex. Accent plant for hot sun or just full sun, though it will take light shade, it is not as compact in growth form under those circumstances. The leaves are 20–90cm long and 0.7–2cm wide, and grey-green in colour. Yucca Hesperoyucca whipplei is a common plant in open chaparral areas. The Chaparral Yucca is pollinated at night by the yucca moth. After 3 years of storage at room temperature, 85% of chaparral yucca seeds germinated. The animals are all mainly grassland and desert types adapted to hot, dry weather. Caespitose and rhizomatous forms of chaparral yucca spread and regenerate vegetatively ([99], review by [60]). In San Diego County, the cover of chaparral yucca did not change much in the first 4 years following fall wildfires. See Shrublands: capsule fruits. Chaparral yucca can grow as a solitary Self-pollinated flowers produced fewer seeds/capsule than cross-pollinated flowers, and the retention rates for fruits produced through self-pollination were 32% of those for fruits produced through cross-pollination. Skip to main content.us. Being a large yucca branching from the base, makes a dramatic focal plant for the desert effect in a non-desert garden. Common in our local region. Fires in San Diego County were larger but less frequent than those in Baja California.

These moths are the only know pollinators of chaparral yucca. Predation) Productivity of the coastal sage scrub was rapid, seasonal, and closely associated with rainfall [26,27]. In January and February, germinated seeds were found in fruits attached to the inflorescence and in fruits lying in the litter beneath parent plants [50]. resulted from self-pollination of monocarpic chaparral yucca plants in Orange County. In the Coast Ranges of California, chaparral yucca was much more abundant at low-elevation (400-1,500 feet (120-460 m)) than high-elevation sites (2,000-2,450 feet (610-750 m)) [118]. Eighteen months after moderate to severe surface fires in blue oak woodlands in the foothills of Sequoia National Park, the density of chaparral yucca was 5 plants/ha. The margin has tiny but sharp serrations. Root tips averaged 0.2 inch (0.5 cm) in diameter, and older root portions were about half that [41]. Skin problems, including acne 10. [118], but when the vegetation and environmental conditions of 67 coastal sage scrub sites were evaluated in southern California and northern Baja California, chaparral yucca was not found on serpentine or limestone substrates. The number of capsules free of larvae was substantially greater for monocarpic than caespitose or rhizomatous forms [61]. Mexico: Chaparral yucca: BCN. Remove the seeds from the pods, allow them to dry, and store in a cool dark location for the winter. Lay the seeds on top of the soil and sprinkle soil over the seeds until they are covered. Monocarpic forms produced the largest capsules with the most seeds, but when mature fruits from all growth forms were combined, the number of seeds/locule was positively correlated with elevation, distance from the coast, and total annual precipitation (P<0.05). A nice plant native in an area that gets to -10 regularly with 10-15" of rainfall. There are gaps between populations in the Santa Ana and Santa Monica mountains, the Santa Monica and Santa Ynez mountains, the San Rafael and Santa Lucia mountains, the Walker Pass region, and western Sequoia National Park.
