Our favorite list of Yucca Plant seeds from around the world.
2070 Spanish Bayonet ( Yucca aloifolia )
Spanish bayonet has an erect trunk, 3-5" in diameter, reaching up to 5-20' tall before it becomes top heavy and topples over. When that happens, the tip turns upward and keeps on growing. The trunk is armed with sharp pointed straplike leaves each about 2' long. The young leaves near the growing tip stand erect; older ones are reflexed downward, and the oldest wither and turn brown, hanging around the lower trunk like an Hawaiian skirt. Eventually the tip of the trunk develops a 2' long spike of white, purplish-tinged flowers, each blossom about 4" across. After flowering, the trunk stops growing, but one or more lateral buds are soon formed, and the uppermost becomes a new terminal shoot. Any other buds become branches, but these are usually few, and the plant has an open, airy habit. Spanish bayonet also produces new buds, or offshoots, near the base of the trunk, forming a thicket.
Z1495 Red Yucca ( Hesperaloe parviflora )
This wonderful desert plant attracts humming birds and butterflies, is deer resistant and works extremely well in xeriscapes.
This plant's tapering leaves grow from a central crown to produce a clumping effect. It goes well in a desert landscape with plants like agave, aloe, and yucca, which have similar form. Coral-pink flower spikes provide attractive color from spring to late summer. Tolerates drought and poor soil.
Hardy to zone 7.
BM70 Texas Tree Yucca ( Yucca faxoniana )
Does well anywhere in zones 5-10. Grows almost 20' tall and spreads about 8' wide. This giant of the genus is native to western Texas and northern Mexico. Its massive stems tower over the desert with 3' long, stiff, dagger-like leaves and huge spikes of ivory flowers. It takes many years to grow to specimen size.
2051 Adam's needle ( Yucca filamentosa )
Also known as bear grass, weak-leaf yucca, Adam's needle looks a little like a small palm, but is actually more closely related to the lilies. The leaves of Adam's needle are strap-like, about an inch wide and up to 2 or 3' long. The leaves are basal; that is, they all originate from one point, taking the form of a rosette. The margins of the leaves are decorated with long curly threads or "filaments" that peel back as the leaf grows, eventually dropping off on older leaves. The inflorescence is very showy and borne on an erect spike up to 12' high. The individual flowers (up to several dozen) are white and about 2" long. The plant dies after flowering and fruiting, but produces lateral buds that start new plants around the edges of the original.
Light: prefers full sun, but will tolerate some light shade.
Moisture: average to dry soild - drought tolerant.
Hardiness: USDA Zones 6-10.
Use in mixed borders and natural areas. Excellent in rock gardens and as an accent among other perennials. Can be grown in outdoor container.
2052 Joshua Tree ( Yucca brevifolia )
A picturesque desert plant, typically with a single, short trunk and many heavy, wide spreading limbs reaching up to 40 feet tall outsied, but can be container raised for many years when young. Leaves are evergreen, stiff and dagger-like, numerous at the ends of branches, 6 to 12 inches long, sharp pointed tip, edges fine toothed, blue green.
Flowers are bell-shaped, 1 ½ inch long, creamy yellow green, occur at the ends of branches in upright 1 to 1 ½ foot long clusters, appearing in spring.
Fruits are light brown to reddish capsule, 2.5 to 5 inches long, 2 inches in diameter, 6 celled, initially fleshy, dries and falls soon after maturity in late spring.
Bark is light brown, initially covered with brown dead leaves, later irregularly scaly ridged and furrowed.
3383 Soapweed Yucca ( Yucca glauca )
This clumping evergreen shrub with narrow leaves produces a startling, 3- to 4-foot-tall flower stalk. The fragrant flowers are pale green or greenish white. It is a tenacious plant in areas of the American West, but adds a touch of the desert to gardens. Soap can be made from its roots and the foliage is used in basket-making.
It is deer resistant, drought tolerant and makes a good bedding plant for rock gardens or xeriscapes. Best suited for zones 4-8.
3427 Beaked Yucca ( Yucca rostrata )
A remarkably beautiful Yucca that forms a large, spherical crown of blue-grayish green, narrow leaves, supported by a moderately tall, solitary trunk, clothed at least in its upper part in a dense skirt of dead leaves. Native to northern Mexico and western Texas, it is slow growing but very hardy to drought as well as severe cold.
TRM659 Dwarf Yucca ( Yucca harrimaniae nana )
One of the best for container growing, often grows only 12" tall and about 12" across.
A tiny, clustering Yucca native to the Great Basin desert in Utah between 1600 and 2400 m. It forms compact rosettes of narrow, bluish-green leaves with filiferous edges and older plants develop a short, thin trunk. It is easy in cultivation, very hardy to drought and freezes and suitable for dry, temperate areas in USDA Zones 5 to 10. This form is separated by some as a distinct species, Yucca nana, but is generally considered to botanically fit well within the variable Y. harrimaniae.

3428 Giant Mexican Desert Palm ( Yucca filifera )
One of the largest and most popular Yuccas, this species from northeastern Mexico can reach a height of about 10 m (33 ft.) tall. The massive trunks are tall and solitary at first and start branching with age. The rigid leaves form a compact crown. It will tolerate light to moderate freezes and is best suited to warm temperate/subtropical areas.
D7853 Soaptree ( Yucca elata )
A native of the US South West that will grow to 20 ft. with leaves 1" wide by
three feet long. The flower stem can rise as much as 10 feet above the plant
with flowers ranging from green to white with tinges of pink.
