The link http://cistus.com/mail_order/plant_catalog/a-b.html Yucca aloifolia spanish bayonet One of the larger hardy yucca, forming a trunk to 5-20 ft.... eventually. A great addition to the garden and fine in a container as well -- easy in both. Leaves are large, to 2 ft, sweeping, and sharply pointed. Mature plants produce spikes of white flowers tinged purple appear in early to mid summer. Full sun to half sun in well-drained soil. Easy. Frost hardy to 0F, USDA zone 7. Agavaceae $14 4D Yucca aloifolia 'Blue Boy' A plant Sean knew at the Berkeley Botanic garden, now sometimes sold as Y. aloifolia 'Purpurea', with somewhat soft, arching leaves that are green with purplish highlights in summer, turning more red in winter temperatures. Very tropical. To 4-6 ft. Sun to part sun and well-drained, lean soil with only occasional summer water once established. Frost hardy to 15 to 20F, mid USDA zone 8. An outstanding pot plant. Agavaceae $15 4D Yucca angustissima 'South Side' A Cistus introduction. This diminutive relative of Y. elata occurs mostly north of the Colorado River in the area fondly regarded as the Arizona strip. Our collection, from the Hualumpai area, was found hanging from cliffs over the Grand Canyon creating a small “tree” to about 3 ft with compact, symmetric heads of leaves adorned with silver filifers. Eventually offsets forming a small colony. A beautiful plant for repetition or for container specimen. And a bit easier to grow than its larger cousin. Particularly beautiful where the sun can backlight the foliage. Drought tolerant though summer water can speed growth in dry areas. Frost hardy in USDA zone 5. Agavaceae $18 4D Yucca baccata spanish bayonet, banana yucca This trunk-forming yucca is a knockout in the landscape with curving trunks -- up to 10 per plant -- that snake out and stand up to 8 ft tall. Green leaves are stiff and decorated with longish filifers. Very architectural! In early summer, short flower stalks carry abundant white flowers. Full sun with excellent drainage, and, for best appearance, occasional summer water. Frost hardy to -20F, USDA zone 5 and possibly colder. Agavaceae $15 4D Yucca baccata var. vespertina 'Hualampai Blue' banana yucca A new Cistus introduction. From our earliest days of botanically exploring the rich area from south western Utah to northern Arizona we’ve noticed the banana yucca, with forms there having upright, very blue leaves looking much like a misplaced sanseverria. This clone, from the south side of the Colorado river in Mojave County, is one of the bluest of the blue. Slowly offsetting clumps have upright leaves, to 4 ft or more, of pale blue adorned with curly filifers. The flowers, cream with nearly red bracts, rise to about 1/2 the leaf height ... but don’t hold your breath for the flowers. This is one of the prettiest yuccas we have come across. Tolerant of all kinds of miserable conditions including drought and poor soil but deserving decent drainage and little push of summer water in the driest spots. Frost hardy in USDA zone 4! Agavaceae $16 6in Yucca carnerosana - Mexican Collection tree yucca A collection from South Neuvo Leon, Mexico, of this widespread tree yucca. To 10 ft or more in the garden with a thick trunk and rigid leaves to over 18" long and graced with curling white hairs along the margins as well as, in this form, a thick ivory colored edge that make the leaves look particularly striking. Best in full sun to only light dappled shade with occasional summer water for best appearance. Frost hardy to 5-10F, mid to upper USDA zone 7, possibly colder with protection. Agavaceae $18 6in Yucca elata SBHMPS 6733 - large form As close to ‘It’ from the Addams Family as you can find in nature, this Cistus collected form is single-trunked and multi-branched yucca, to 10 ft tall and more, with long, hanging leaves and "gobs" of white flowers on tall stalks in summer. What's not to love? Sun, well-drained soil, and occasional summer water for best growth and appearance. Frost hardy to -10F, USDA zone 6, or lower. Agavaceae $15 4in Yucca faxoniana - Albuquerque Another of the tough Yucca faxoniana, this one collected near Albuquerque, New Mexico with the same 3-4 ft rosettes of stiff, emerald-green leaves, each leaf adorned with symmetric, pearly cream to brown filifers. Quick to form full sized rosettes; slow to build a trunk that eventually reaches to 16 ft or more; and slow to branch. Fastest when given plenty of root room, free draining soil, and some supplemental water in very dry summer places. Excellent container plants. Prefer bright light. USDA zone 7 with some success in warm zone 6 with excellent drainage and protection from freezing winds. Agavaceae $15 4D Yucca filamentosa 'Bright Edge' variegated adam's needle A handsome yucca, popular for its long, strappy and lax leaves, to 2-3 ft long, green-centered with gold margins and curly threads on the edges. Flowers are very showy, white on flower stalks to 12 ft tall. Excellent as a visual accent with leaf edges that aren’t sharp so it can line a path or border. Lean, well-drained soil in full sun with average summer water for best color, though tolerates some shade and some drought. Definitely frost hardy in USDA zone 7 and reportedly in USDA zone 5. Agavaceae $14 4in Yucca filamentosa 'Gold Stripe' Discovered in the nursery as a striped sport of Y. filamentosa 'Gold Sword', each leaf adorned with very narrow creamy gold and blue green lines. Upright and vigorous to 18" in height and 3 ft or so across with, typically, 4 ft spikes of white flowers, most often in June. Full sun to dappled shade; otherwise extremely tolerant of any conditions thrown at it. Frost hardy in USDA zone 4. Agavaceae $12 4D Yucca filamentosa 'Hairy' Dazzling form of this southeastern native selected at the JC Raulston Arboretum in the early 1990s and just now becoming available. Trunkless 3 ft rosettes of soft-textured but wide, blue tinted leaves are adorned with particularly large numbers of curly white threads, giving the entire plant a dazzling cobweb effect. Wonderful placed where backlighting occurs. One of the easiest to grow species in any soil, with bright light to dappled shade. Frost hardy in USDA zone 4. Agavaceae $16 4D Yucca filifera Tree forming yucca and one of the most sculptural, the trunk eventually forming a swollen base and slowly branching. To upwards of 15 ft tall, with 2 ft rosettes of tightly held blue-green leaves covered with delicately intertwining filifers. Fabulous garden or container specimen for full sun and well-drained soil. Happy with summer moisture and winter drought, though quite versatile provided temperatures don't drop below 15F for extended periods. Cold hardy into the mid teens, mid-USDA zone 8; colder with exceptional drainage. Agavaceae $16 6in Yucca gloriosa 'Tiny Star' tiny star soapwort Charming yucca, small and slow growing, to only 18" tall x 3 ft wide eventually, with variegated leaves, creamy yellow edged in green. Fits well into a rock garden. A selection of a southeastern US native, introduced from Japan in the 1970s by plantsman Barry Yinger, this form accepts the usual yucca conditions, sun to light shade, well-drained soil, and occasional water in summer for best appearance. So far, none have been seen to flower. Frost hardy to at least 0F, USDA zone 7. Agavaceae $16 4D Yucca gloriosa 'Tricolor' One of the most useful of the trunk-forming, southeastern US native yuccas found growing from South Carolina all the way around to the Gulf side often within sea spray. With 2-3 ft rosettes of upwardly pointed leaves and trunks as high as 4 ft, this form has foliage variegated with cream and light yellow and infused with pinks especially with winter frost. Tolerant and even fond of average garden water and very long lived in container. Very good focal point for the garden. Has been quite happy and frost hardy to mid USDA zone 7. Agavaceae $16 4D Yucca linearifolia One of the most beautiful yucca species, related to Y. rostrata. The 3 ft rosettes atop an eventual 3-8 ft trunk resemble the Australian grass trees, xanthorroea, or a dim version of Dasylirion quadrangularis. Leaves are flattened and somewhat triangular, spring-green to nearly turquoise, and flowers are white on stalks to 3 ft or so above the foliage. Full sun to part shade with good drainage and lean soil. Best with occasional summer water. Found in a few scattered localities, these are from north of Galleana, NL, Mexico, in a most diverse habitat. Though the southern habitat would suggest little frost tolerance, these have so far withstood 5F, mid USDA zone 7. Agavaceae $18 4in Yucca linearifolia 'Dusky Blue' One of the most beautiful yucca species, related to Y. rostrata. The 3 ft rosettes atop an eventual 3-8' trunk resemble the Australian grass trees, Xanthorrhoea, or a dim version of Dasylirion quadrangularis. Flattened somewhat triangular leaves of spring green to nearly turquoise and white flowers to 3' or so above the rosette. From only a few scattered localities, these from north of Galleana, NL, Mexico, in a most diverse habitat. This form is particularly blue and quite vigorous adding 6-8" of trunk each year. Our plant often elicits comments from garden visitors. The southern habitat of the species would indicate lack of frost tolerance but plants have so far withstood 5F, mid USDA zone 7. Full sun to partial shade and summer water with, as always, well-drained soil. Agavaceae $18 4D Yucca nana Exquisite and tiny yucca from the San Rafael Swell of southern Utah. The 6-8" rosettes, with their undulate, glaucous blue leaves edged white, seem as if a bunch of blue star fish were playing leap frog. Slowly multiplying to form a small colony. Spectacular in garden or in pots: we have placed ours in a stone wall. Would love bright light and free draining soil, preferably high in mineral content, but, really, not very fussy. Small 2-3 ft spikes of pearly white flowers appear on mature plants in May and June. Frost hardy in USDA zone 4, if not 3. Agavaceae $16 4D Yucca periculosa From semi-arid slopes at mid to high elevations in southern Mexico, this small tree, to 20 ft or so and eventually branching, forms multiple rosettes of blue-green leaves, with evenly spaced, small filifers and outward facing flowers. For sun, lean soil, and dry places but enjoys an occasional summer thunderstorm. Has been unusually tolerant of frost for its southern latitude habitat, being reliable to about 20F, USDA zone 9, and a bit lower if winter dry. Otherwise a particularly nice container plant for many years, appearing like bonsai with its swollen caudex of a trunk. Agavaceae $15 4D Yucca recurvifolia 'Gold Ribbons' A Cistus introduction. This large growing native, from the Carolinas to the Gulf in sandy spots, forms a stunning rosette of weeping leaves and eventually a trunk to 4-5 ft. The plant is useful in all forms but Y. recurvifolia ''Gold Ribbons', can serve as a striking focal point or container plant with its blue dusted leaves and wide center strip of deep creamy yellow. We have used it as a substitute for the more spectacular, gold variegated, New Zealand flax (Phormium) in exposed or particularly frosty areas. Did we say spectacular? Fairly dry to quite damp conditions; decent drainage a plus. Full sun to dappled shade. Not advisable to let too many leaves collect in the crown if in shade. USDA zone 7; 6 in protected spots. Agavaceae $16 4D Yucca recurvifolia 'Margaritaville' Fabulous yucca, evergreen with soft foliage, variegated in creamy yellow striped green with green edges. Very showy. Slow growing, to 4 ft x 6 ft eventually, with tall spikes of ivory bell flowers in summer. Best in full sun to part shade with occasional summer water for best appearance. Frost hardy in USDA zone 7. Agavaceae $18 4D Yucca recurvifolia 'Marginata' The soft leaves on this large, handsome yucca are green-centered and yellow-edged, eventually to 3-4 ft long and arching from a trunk that can reach over 3 ft tall. Expecially lovely with large trusses of open white flowers in summer reaching high above. Very successful in a container, but happy in the garden as well. Full sun is best. Drought tolerant but appreciates occasional summer water. Cold hardy in USDA zone 6b. Agavaceae $18 4D Yucca rigida Bold textured relative of the stunningly gorgeous Yucca rostrata, spending its very long youth as a 2 to 3 ft rosette of 1" wide, silver-blue leaves, eventually forming trunks to 5 to even 8 ft with small candelabras of white flowers in summer at maturity. This species from northern Mexico requires full sun to dappled shade in the most deserty areas and a touch of additional water in the driest spots. Not particular about soil as long as its not sitting in water. Our plants are putting on about 6" of trunk each season. Frost hardy in warm USDA zone 7. Agavaceae $16 6in Yucca rostrata - Black Gap, TX collection From the Big Bend region of Texas this colony, forming the northernmost habitat for the species and the only one in the United States, gives a beautiful cast to the entire landscape. Growing to over 10-12 ft, occasionally branching into small trees with 4-5 ft rosettes, they are truly a stunning creature and a perennial in my top 10 favorite plants. That says a lot! Ours are seed grown and beautiful as garden or pot specimen with many hundreds of leaves in each, rustling like grass off a thickened trunk…but wait, there’s more! As an already frost hardy yucca, this is a northern colony, plants of which have survived in USDA zone 5, making it one of the two frost hardiest tree yuccas. Agavaceae $16 6in Yucca rostrata 'Sapphire Skies' A Cistus introduction. Although Yucca rostrata is one of the most gorgeous species available, and definitely one of our top 500 favorite plants, it is exceedingly slow to reproduce from offsets, seed is difficult to come by, and seedlings vary as to their...blue-osity. Yucca rostrata 'Sapphire Skies' is a selection from one of our collections in the early 90s in northern Mexico, out of a seed batch of stunning blue-leaved plants. Through the magic of tissue culture, we now have a reliable source. These vigorous young plants quickly form a 3 ft, multi-leaved rosette of nearly jade-blue, forming 3 to 4 ft plants in 7 or 8 years under good conditions, eventually to 10 ft or more. Excellent container plants, providing fine architecture, or repeated in the dry garden and looking of dusty blue fireworks from a distance. Particularly beautiful reflected in late afternoon/evening light. Full sun to dappled shade. Not particular about soil, excepting standing water. Some supplemental irrigation in dry summer places. Frost hardy in USDA zone 7; has been successful in zones 5 and 6 including the Denver Botanic Garden (Really!). Agavaceae $16 4D Yucca rupicola twist leaf yucca This large textured species from the Texas hill country consists of slowly clumping, undulant leaves, 1 to 2" wide, of deepest green. Particularly striking when planted with silver-blues such as festuccas or other blue tinted, rosette-forming plants. An easy care creature if provided well-drained soil, supplemental summer water in exceedingly dry places, and bright light, though at home in dappled shade if leaves do not collect in its crown. Frost hardy in USDA zone 6. Agavaceae $16 6in Yucca schottii 'Chiricahua High' Schott's Yucca, Moutain Yucca A Cistus Introduction, our collection from near the summit of the Chiricahua Mts., a hardy yucca with very blue-gray leaves, to 3 ft long and sharply pointed, both stiff and more flexible than other "tree" yuccas. Eventually to 10 ft tall, single-trunked in youth to about 6 ft tall x 4 ft wide, then multi-trunked. Early summer flowers are white on tall stalks. For sun to part shade. An excellent garden species, both very drought tolerant and very frost hardy, accepting temperatures to -10F, USDA zone 6. Agavaceae $14 4D Yucca tehuacana A most handsome, trunk-forming yucca from the Mexican state of Puebla, to an eventual 8-10 ft -- possibly more, but none of us will live that long. Narrow, blue-green leaves in abundance make a beautiful and most architectural rosette even before lift-off. Flowers are white tinted rose-pink on slightly leaning towers. Sun, lean soil, and some summer water to boost growth. Frost hardy to 10 to 15 F, low to mid USDA zone 8 if winter dry; otherwise protect below 15F. Fabulous container plant. Agavaceae $16 6in Yucca thompsoniana Thompson's yucca Charming tree yucca, reaching up to 8 ft tall x 4 ft wide with leaves that are stiff and powder blue with serrated margins and early summer flowers, white on tall stalks above the leaves. Related to and sometimes overlapping with Yucca rostrata though somewhat shorter and more branched, the multiple heads looking something like a miniature Joshua tree (Y. brevifolia). Full sun with good drainage and some summer water is best. Frost hardy to -20F, USDA zone 5 or even lower. Agavaceae $15 4D Yucca torreyi torrey's yucca, spanish dagger Picturesque, very large yucca with leaves in excess of 4 ft, eventually forming a large shrub or small tree, usually single trunked, to 10 ft and taller with great age. Mature plants produce white bell flowers on 4 ft spikes, usually in spring but not every spring. Native from southwestern Texas to the mountains of Coahuila, Nuevo Leon, Mexico, this represents a particularly blue-leaved form from south of the border. Best with lean soil and good drainage in full sun or very light shade. Drought tolerant but faster growing with occasional summer water. Frost hardy to 0F, USDA zone 7. Agavaceae $16 6in Yucca treculeana Tall yucca, its trunk reaching to 12 ft with stiff bayonet-shaped leaves, to 2” wide and 3 ft long, arranged evenly around the thick trunk. Spectacular by itself but when it grows up, in say 4 to 5 years, a giant flower stalk appears adorned with white flowers. Stunning! Originating in the southwestern United States and in Mexico, these are frost hardy to USDA zone 7. Agavaceae $16 |
