Beaked yucca Yucca rostrata
ABOUT
Yucca rostrata, commonly known as Beaked Yucca, is a visually striking plant that exhibits a rugged beauty typical of desert flora. The plant's most distinctive feature is its spherical crown of long, thin, blue-green leaves. These pointed leaves, with their distinct silver-blue hue, radiate outwards from the top of a thick, woody trunk, creating a dense and symmetrical pom-pom-like appearance. The leaves have a very fine, hair-like filament that curls off the edges, giving the foliage a soft, yet spiky texture. Over time, as new leaves grow and old ones die, a fibrous, rough skirt of dead leaves often hangs around the trunk, adding to the plant's unique character. Beaked Yucca blooms with a towering flower spike that emerges from the center of the leaf cluster, bearing a multitude of white, bell-shaped flowers. These flowers are typically dense and clustered, forming a bold contrast against the blue-green foliage, creating an eye-catching display that can be quite a spectacle. Overall, Beaked Yucca has a sculptural quality, with its combination of the stiff, straight trunk topped with a sphere of gracefully arching leaves. This distinctive form gives the plant a strong architectural presence that is highly prized in landscape design for adding vertical interest without significant width.

WaterBeaked Yucca should be watered sparingly; overwatering can lead to root rot. In the active growing season, spring through fall, water when the top inch of soil feels dry, typically every 1 to 2 weeks, adding about 1 gallon for larger plants or 16 ounces for smaller pots to ensure soil is moist but not waterlogged. During winter, reduce watering to once a month or less, as the plant enters a dormant state. Adjust the frequency based on temperature and humidity, ensuring the plant can dry out between waterings.
LightBeaked Yucca thrives in full sun to partial shade. The best spot for it is a location where it can receive direct sunlight for at least 6 hours a day. However, it's adaptable and can tolerate some light shade, especially in the hottest parts of the day.
TemperatureBeaked Yucca prefers temperatures between 30 and 90 degrees Fahrenheit, thriving in warm environments. It can withstand temperatures as low as 5 degrees Fahrenheit, making it quite cold-hardy. The ideal temperature for robust growth is within the range of 70 to 80 degrees Fahrenheit.
PruningBeaked Yucca benefits from pruning to remove dead or damaged leaves and to maintain its aesthetic appearance. Pruning is best done in the spring, before new growth begins. Prune off old flower stalks at their base and trim away any brown tips or damaged leaves as needed. Regular pruning is typically not required, so it suffices to check the plant annually.
CleaningAs needed
SoilBeaked Yucca thrives in a soil mix that is well-draining and sandy. A common recipe might include a mix of perlite, coarse sand, and compost in equal parts. The ideal soil pH for Beaked Yucca should be slightly acidic to slightly alkaline, around 6.0 to 7.5.
RepottingBeaked Yucca should be repotted every two to three years to ensure that the soil does not become compacted and nutrient-deficient. Over time, as the plant grows, it may require more frequent repotting.
Humidity & MistingBeaked Yucca prefers dry air and does not require high humidity levels. It is well adapted to arid conditions, making typical household humidity levels generally suitable for this plant.
Suitable locationsIndoor
Place in a sunny spot, water sparingly.
Outdoor
Full sun, well-draining soil, protect from extreme cold.

Life cycleYucca rostrata, commonly known as Beaked yucca, starts its life cycle as a seed, which upon germination, grows into a small seedling. The seedling gradually develops a sturdy stem and long, narrow leaves that form a tuft at the top of the trunk. As it matures, the plant undergoes a vegetative growth phase where it continues to develop its distinctive spherical head of silver-blue leaves and a thickening trunk, which can become tree-like over many years. Once mature, usually after several years, the Beaked yucca produces towering flower spikes up to 4 feet tall, with white, bell-shaped flowers that attract pollinators like moths. Following pollination, the flowers develop into capsule-like seed pods that dry, split open and release seeds to start a new generation. The Beaked yucca can live for multiple decades, with older plants continuing to produce new flower stalks annually during their growth season.
PropogationPropogation time
Spring-Early Summer
Propogation: Yucca rostrata, commonly known as Beaked yucca, is usually propagated through the division of offsets, which are small 'pup' plants that grow at the base of the parent plant. The best time to propagate Beaked yucca by offsets is during the late spring or early summer when the plant is actively growing. To propagate, carefully remove the offset from the main plant, ensuring that the pup contains some roots. Let the offset dry for a couple of days to develop a callous over the cut surface, which helps prevent rot. Plant the offset in a well-draining soil mix and water it sparingly until it establishes and starts showing new growth, which indicates that it has rooted successfully.
