Types of Yucca Plants (With Pictures) – Identification Guide

Let’s delve into the diverse world of yucca plants and discover their distinctive features.

Adam’s Needle and Thread Yucca Plant (Yucca Filamentosa)

Adam’s Needle and Thread Yucca, also known as Yucca Filamentosa, is a flowering variety that produces a dramatic tall stalk adorned with a massive cluster of white flowers. This yucca species thrives in USDA zones 4 – 11 and is remarkably cold-hardy, withstanding temperatures as low as 5°F (-15°C). The Yucca Filamentosa is a popular choice for evergreen landscapes, featuring long sword-shaped green leaves that reach up to 3 ft. (1 m) in height. One key identifying feature of this yucca plant is the thin filaments present in its foliage, which lend it the name ‘needle and thread.’

Adam’s Needle ‘Color Guard’ (Yucca Filamentosa ‘Color Guard’)

Yucca Filamentosa ‘Color Guard’ is a remarkable variety of Yucca Filamentosa, distinguished by its yellow and green variegated leaves. The foliage grows in a rosette form, showcasing distinctive curly threads that turn pink and rose-colored during the winter months. This clumping shrub can reach a height of 2 to 3 ft. (0.6 – 1 m) and produces large clusters of whitish flowers on a long stalk in the middle of June. The Yucca ‘Color Guard’ thrives in sandy soil and is perfect as a border shrub, deterring animals and intruders with its sharp leaves.

Adam’s Needle ‘Excalibur’ (Yucca Filamentosa ‘Excalibur’)

Adam’s Needle ‘Excalibur,’ also known as Yucca Filamentosa ‘Excalibur,’ is an impressive yucca variety with stiff, sword-shaped leaves in a bluish-green to gray-green color.

(1.5 m) high flowering stem. This yucca plant is an excellent choice for creating a dramatic statement in your backyard and thrives in USDA zones 5 – 10.

Spineless Yucca Plant (Yucca Elephantipes)

Spineless Yucca, scientifically known as Yucca Elephantipes, is one of the tallest yucca trees, reaching staggering heights of up to 30 ft. (9 m). Unlike other yucca species, this plant lacks sharp spines on its leaves, hence the name ‘spineless.’ The smooth, leathery evergreen leaves grow in a spiral rosette shape, evoking the image of a majestic palm tree. While Spineless Yuccas are commonly found in arid regions, they can also thrive indoors as houseplants, growing up to 5 ft. (1.5 m) high. However, their slow growth means it will take several years for them to reach that height.

Spanish Bayonet (Yucca Aloifolia)

Spanish Bayonet, scientifically known as Yucca Aloifolia, is an ornamental yucca species with long, sword-like leaves resembling a dagger. The stiff evergreen blades have sharp serration along the margins and a pointed tip, further enhancing their resemblance to a sword. This tall shrub-like tree grows to heights between 5 and 10 ft. (1.5 – 3 m) and forms dense crowns with spiky leaves on multiple stems. Spanish Bayonet complements tropical trees beautifully and thrives in arid landscapes, particularly in coastal regions. This yucca species is well-suited for both outdoor and indoor cultivation.

The Weak-Leaf Yucca, scientifically known as Yucca Flaccida, is a charming evergreen shrub that grows up to 2 ft. (60 cm) tall, with a spread of up to 5 ft. (1.5 m). This yucca species boasts sword-shaped leaves with sharp points that tend to droop or bend over. It is often referred to as Adam’s Needle, and it is related to Yucca Filamentosa. When in bloom, the Weak-Leaf Yucca produces beautiful bell-shaped white flowers on long stems. Notable cultivars of this yucca include ‘Garland Gold’ and ‘Golden Sword,’ exhibiting spectacular rosette growth with yellow and green leaves.

Cultivars of Spanish Dagger include ‘Variegata’ and ‘Bright Star.’ The ‘Bright Star’ yucca is an attractive ornamental shrub with vibrant green leaves accented by yellow margins. This spiky plant thrives in USDA zones 7 – 11 and exhibits a light reddish-pink hue in colder temperatures.

Red Yucca Plant (Hesperaloe Parviflora)

The Red Yucca, scientifically known as Hesperaloe Parviflora, features grass-like leaves and pinkish flowers that grow on tall, narrow spikes. While not a true yucca species, this bushy shrub bears a strong resemblance to yucca plants, with spineless leaves arranged in a rosette shape. The bluish-green leaves of this yucca-like plant take on a reddish-bronze hue in cold weather. Hesperaloe Parviflora is drought-tolerant and thrives in USDA zones 6 – 11, making it an excellent choice for borders, containers, and Mediterranean gardens.

Joshua Tree (Yucca Brevifolia)

The Joshua Tree, scientifically known as Yucca Brevifolia, is a fast-growing desert tree synonymous with the arid southwestern U.S., particularly the Mojave Desert.
