Spanish Dagger Yucca gloriosa Bright Star = 'Walbristar' (PBR) (v)
ABOUT
Yucca gloriosa Bright Star, commonly known as Spanish dagger, is an ornamental plant known for its striking appearance. This variant, 'Walbristar', features bold, variegated foliage that provides a pop of color in the landscape. Each blade-like leaf is sharply pointed and emanates from the plant's base in a rosette formation, contributing to its architectural statement. The leaves are edged with vibrant, creamy-yellow margins that stand out against the bluish-green center, offering a visual contrast that's particularly eye-catching. These colorful margins may also take on pinkish hues, especially when exposed to direct sunlight or during cooler temperatures, adding to the plant's seasonal interest. The Spanish dagger's foliage texture is rigid and sturdy, creating a spiky silhouette, while the leaves' surfaces have a slight gloss, enhancing their coloration. The plant blooms with showy clusters of white, bell-shaped flowers that rise above the foliage on tall spikes, although the primary attraction remains its year-round foliar display. The overall impression is that of a tough, drought-tolerant plant that adds a tropical or desert-like feel to gardens or landscapes while requiring minimal care.

Common names
Yucca gloriosa 'Walbristar' Bright Star.
- Toxicity
To humans
The Spanish dagger is generally not considered toxic to humans. However, as with many plants, ingestion of large quantities can lead to discomfort or potential negative reactions due to the plant's saponins content. Saponins can cause vomiting, nausea, and diarrhea if ingested. It is wise to avoid eating parts of this plant and to handle it with care to prevent mechanical injury from its sharp leaves.
To pets
The Spanish dagger can be toxic to pets if ingested. The saponins present in the plant can cause vomiting, diarrhea, and drooling in animals. In severe cases, ingestion can lead to depression, lack of appetite, and in very rare instances, can cause more severe symptoms. It is important to keep pets away from this plant to prevent accidental ingestion and the subsequent risk of poisoning.

- Water
Spanish dagger should be watered sparingly as it is a drought-tolerant plant, well-adapted to arid conditions. In general, watering once every 1-2 weeks during the active growing season is sufficient, but make sure to allow the soil to dry out completely between waterings. In the winter months, you can reduce watering to once a month or even less frequently, depending on your climate. When you do water, give the plant a thorough soaking, which may be around 1-2 gallons depending on the size of the pot or the plant in the landscape.
- Light
Spanish dagger thrives best in full sunlight, where it can receive at least 6 to 8 hours of direct, unfiltered sunlight daily. It is well-suited for south-facing windows indoors or unobstructed areas in the garden that provide full sun exposure.
- Temperature
Spanish dagger can tolerate a wide range of temperatures but performs best in conditions between 60°F and 80°F. It can withstand temperatures as low as 5°F but should be protected from freezing temperatures to prevent damage. During the summer, it is quite resistant to heat and can handle temperatures exceeding 90°F without issue.
- Pruning
Spanish dagger typically requires minimal pruning, mainly for aesthetic reasons or to remove dead leaves. Pruning can be done in the spring or early summer to shape the plant or to cut back any frost-damaged tips. Cut back to a well-placed side shoot or remove the entire leaf, and remember that the leaves have sharp tips, so wear protective gloves.
- Cleaning
As needed
- Soil
Spanish Dagger thrives best in a well-draining, sandy or gritty soil mix with a slightly acidic to neutral pH of about 5.5 to 7.5. A recipe for a suitable soil mix could include equal parts of sand, garden soil, and a gritty amendment like perlite or pumice to enhance drainage.
- Repotting
Spanish Dagger typically does not require frequent repotting; it should be repotted every 2 to 3 years or when it outgrows its current pot. Be sure to use a well-draining soil mix during repotting.
- Humidity & Misting
Spanish Dagger is tolerant of a wide range of humidity levels and does well in average household humidity conditions. It does not require high humidity and can withstand dry air.
- Suitable locations
Indoor
Place Spanish Dagger in bright, indirect light indoors.
Outdoor
Plant in full sun to partial shade, well-draining soil.

- Life cycle
The life of Spanish Dagger 'Walbristar', commonly known as Yucca gloriosa 'Bright Star', begins with seed germination, where warmth and moisture encourage the seed to sprout roots and shoots. As a seedling, it develops a rosette of variegated leaves, requiring adequate sunlight and well-draining soil to establish its root system. In the vegetative stage, 'Bright Star' forms a woody stem and continues producing attractive, sword-shaped leaves edged in cream to golden-yellow hues, growing slowly into a rounded, bush-like shape. After a few years, when mature, it produces towering spikes of fragrant, bell-shaped white to pale pink flowers in the summer, which are pollinated by moths. Following pollination, seed pods form, dry out, and eventually release seeds to start a new generation. Over many years, this evergreen perennial may produce offsets or pups at the base, which can be separated to propagate new plants.
- Propogation
Propogation time
Spring-Early Summer
Propogation: Yucca gloriosa 'Bright Star' is commonly propagated through the division of its offsets, which is done during the spring season into early summer. To propagate via division, identify a healthy offset or pup that has grown around the base of the parent plant. Using a sharp, sterile knife or spade, carefully separate the offset from the main plant, ensuring that it has some roots attached. The separated pups can then be potted into individual containers using a well-draining soil mix. It is important to water sparingly initially to prevent rot, allowing the soil to dry out completely between watering. The new plants should be kept in a warm, bright, indirect light position until established, after which they can be gradually acclimatized to direct sunlight.
