Adam's Needle Yucca filamentosa 'Color Guard' (v)
ABOUT
Yucca filamentosa 'Color Guard', also known widely as Adam's needle, is a visually striking plant primarily known for its distinctive foliage. Its leaves are long and sword-shaped, emanating from a central rosette that grows close to the ground. What sets 'Color Guard' apart is the eye-catching coloration of its leaves; they exhibit a vibrant variegation, where the center of each leaf bears a broad, creamy-yellow stripe that runs along its length, flanked by green margins on either side. During the warmer months, the cream-colored stripe can take on a pinkish hue, especially when exposed to more direct sunlight, adding to the visual appeal of the plant. The edges of the leaves are adorned with curly filaments, which are fine, thread-like growths that add texture and a hint of whimsy to the overall appearance of the plant. Adam's needle blooms in the summer, producing a towering stalk that rises from the center of the leaf rosette. Atop this stalk, an array of bell-shaped, white flowers forms, which can attract a variety of pollinators such as bees and butterflies. The bloom of Adam's needle creates a stark contrast with its foliage, as the tall stalk holds the flowers well above the rosette, creating a vertical element in its overall shape. After flowering, Adam's needle may produce seed pods that add further interest to the plant's profile into the late season.

ToxicityTo humans
Adam's needle, overall, is not considered to be highly toxic to humans. However, it can cause minor irritations if ingested or if the sap comes into contact with the skin. The plant's sharp leaves can also cause physical injury due to their pointed tips. Ingestion of parts of Adam's needle, particularly the leaves or flowers, can lead to mild stomach discomfort, including nausea, vomiting, or diarrhea in some individuals. The saponins present in the plant are considered toxic but are poorly absorbed by the human body, and therefore usually do not cause serious harm. It is still advisable to prevent children from ingesting any part of the plant.
To pets
Adam's needle is considered to be mildly toxic to pets such as dogs and cats. Ingestion can lead to symptoms like vomiting, diarrhea, and drooling due to the saponins it contains which can irritate the pet's gastrointestinal system. It is important to keep an eye on pets if these plants are within their reach and consult a veterinarian if any severe reactions or symptoms are observed after ingestion. Additionally, the sharp leaves can cause physical injury or punctures if a pet tries to chew on them or brushes past them forcefully. It's best to prevent your pets from ingesting any part of the plant to avoid these symptoms and potential injuries.

WaterAdam's Needle prefers to be watered deeply but infrequently, allowing the soil to dry out completely between watering sessions. Typically, you should water the plant about once every 1 to 2 weeks during the active growing season, decreasing frequency to once a month or less during cooler months. Provide approximately 1 gallon of water per session to thoroughly saturate the roots, ensuring that water penetrates deep into the soil. Overwatering can lead to root rot, so err on the side of underwatering rather than giving too much.
LightAdam's Needle thrives best in full sun to partial shade. It should be planted in a location where it receives at least 6 to 8 hours of direct sunlight a day. The plant is well suited for sunny borders, rock gardens, or as a focal point in a mixed bed where light levels are high.
TemperatureAdam's Needle is highly adaptable and can withstand temperatures as low as -20°F and as high as 90°F, making it suitable for various climates. Ideally, it prefers to be in an environment where temperatures range between 60°F and 80°F. It's a very hardy plant that can tolerate heat and cold well.
PruningAdam's Needle requires minimal pruning, usually just to remove dead foliage or spent flower stalks. Prune in the late winter or early spring before new growth starts. Dead or damaged leaves can be cut back to the base to maintain a tidy appearance. Flowering stems should be removed after blooming to keep the plant looking neat.
CleaningAs needed
SoilColor Guard Yucca prefers a well-draining soil mix with sandy or gravelly components to prevent root rot. The ideal pH level for this plant is neutral to slightly alkaline, between 5.5 and 7.5. A mix of 50% garden soil, 30% sand, and 20% peat or compost would support healthy growth.
RepottingColor Guard Yucca is slow-growing and does not need frequent repotting; it may be repotted every 2 to 3 years. Use a fresh well-draining soil medium and a pot only slightly larger than the previous one.
Humidity & MistingColor Guard Yucca is highly tolerant of dry air and does not require high humidity; it thrives in low to average household humidity levels. Avoid overly humid conditions to prevent potential fungal issues.
Suitable locationsIndoor
Place in bright indirect light, avoid overwatering.
Outdoor
Plant in full sun, well-drained soil, and space adequately.

Life cycleYucca filamentosa 'Color Guard', commonly known as variegated Adam's needle, begins its life as a seed, which germinates in warm, well-draining soil where it grows into a small seedling. The seedling then develops into a rosette of variegated, sword-shaped leaves, and over several years, it forms a clump with multiple rosettes. As it matures, the plant produces tall flower stalks in summer, which are adorned with bell-shaped, creamy white flowers that are attractive to pollinators. After flowering, seed pods develop and, when they dry, release seeds to start the next generation. The plant is perennial, returning each year from the same root system, and as it ages, the clumps may become large and can be divided to propagate new plants. The parent plant can live for many years, slowly expanding in size and often flowering annually.
PropogationPropogation time
Spring-Early Summer
The most popular method of propagation for Yucca filamentosa 'Color Guard', commonly known as variegated Adam's needle, is through division of the clumps. This is best done in the spring, as the plant is exiting its dormancy period and starting to grow. To propagate by division, you carefully dig up the parent plant and separate the rosettes that have formed at the base. Each rosette should have a segment of root attached. These divisions can then be replanted in well-draining soil at the same depth they were previously growing. It's important to water the new plants thoroughly to help establish them, but then allow the soil to dry out between waterings to prevent rot. With this method, the plants you propagate will be identical to the parent plant, including the striking variegated foliage.
