What Is Beargrass Yucca – Learn About Beargrass Yucca Plants

By: Bonnie L. Grant, Certified Urban Agriculturist

Yucca are evergreen, perennial, arid region plants. They require plenty of sun and well-drained soil to thrive. Beargrass yucca plants (Yucca smalliana) are commonly found in sandy soil in the southeastern United States. Growing beargrass yucca in the home landscape requires similar soil and exposure. Surprisingly, the plant has naturalized in areas like Illinois, a USDA zone 4 to 5 region. For a desert plant, it has adapted to extreme cold and even occasional frost.

What is Beargrass Yucca?

Beargrass yucca looks similar to the common Adam’s needle yucca. To identify beargrass yucca vs. Adam’s needle, you just need to look at the leaves. Beargrass yucca has narrower leaves which are flattened and also bear a smaller flower. Yucca filamentosa, or Adam’s needle, is commonly misidentified as Yucca smalliana. Each is of similar size, but their leaf and flower characteristics indicate that they are different species in the same genus.

Beargrass yucca plants are unmistakable succulents with sword-like leaves. These leaves are softer than and not as dangerous as the sharp, knife-edged Adam’s needle yucca foliage – it has even been termed weak-leaf yucca because of this. Individual leaves may approach 30 inches (76 cm.) in length. Leaves all rise from a central rosette. As new leaves appear, the lower older leaves dry and hang down against the stem.

The beautiful flowers are born on stems which may be up to 8 feet (2.4 m) in length. Adorning this stem are the saucer-shaped flowers, dangling in panicles of iridescent creamy white. Fertilized blooms become 3-inch (8 cm.) long pods bearing large, black flat seeds.

Additional Beargrass Yucca Information

In the wild, beargrass yucca can be found growing in sand and sun locations. In areas where it has naturalized, it may be found in vacant lots, roadsides, woodlands, prairies, and open woods. In southeastern America, gardeners who are growing beargrass yucca may inadvertently spread the plant, as the seed is a speedy and ready germinator, and young plants seem to be able to get a foothold in a variety of settings.

The plant can also reproduce by developing offsets or pups. This is common in the succulent group of plants. Young pups can be divided from the mother to create individual specimens. In nature, the pup often continues to grow alongside the parent, only to eclipse it when the offset is mature.

Beargrasss Yucca Care

Yuccas prefer moderate to dry conditions, full sun and well-draining soil. It is this last requirement – well-draining soil – that is crucial because boggy sights can lead to root rot and enhance fungal disease issues. Sandy soil is preferred, but these tolerant plants can also thrive in loam, clay, rocky or other types of soil as long as it drains freely.

Remove spent flower stalks after blooming to help the plant channel its energy into foliar growth and prevent the spread of the yucca. Water in the morning or under the leaves to prevent the formation of black spot. Remove damaged leaves as they occur. For the most part, beargrass yucca care is minimal. This stoic plant can be planted and enjoyed without any fuss.
