WaterAdam's needle prefers to be watered deeply but infrequently, adapting well to dry conditions once established. When first planted, water the plant every few days to help it establish, providing about 1 gallon per watering session. After establishment, reduce watering to once every week or two, depending on the weather conditions, ensuring you provide about 1-2 gallons to reach the deep roots. During hot, dry spells, water every week, but during cooler months, you can cut back to once a month or if rainfall is sufficient, not at all. Always allow the soil to dry out between watering sessions to prevent root rot.
LightAdam's needle thrives in full sunlight to partial shade. It prefers a location where it can receive at least 6 hours of direct sunlight daily. If planted indoors, place it near a south-facing window for optimal light conditions. Adam's needle is tolerant of various light conditions, but its growth and flowering are best in ample sunlight.
TemperatureAdam's needle is hardy and can withstand temperatures as low as -30 degrees Fahrenheit, making it suitable for many climates. It performs best in temperatures between 60 and 90 degrees Fahrenheit. Protecting the plant from extreme cold winds and excessively high temperatures will maintain its health and appearance.
PruningAdam's needle benefits from occasional pruning to remove dead or damaged leaves and spent flower stalks, enhancing the plant's appearance and preventing disease. Prune in the spring, cutting back any unsightly foliage at the base. Annually removing the old flower stalks after they have bloomed encourages better growth for the following season.
CleaningAs needed
SoilAdam's Needle 'Bright Edge' thrives in well-draining soil with a soil pH ranging from 5.5 to 7.5. A suitable mix can be made of equal parts sand, perlite, and potting soil. This composition ensures adequate drainage to prevent root rot while supplying essential nutrients.
RepottingAdam's Needle 'Bright Edge' doesn't require frequent repotting; it can usually be repotted every 2 to 3 years. Due to its slow growth and tolerance for being slightly root-bound, repotting is often only necessary when it outgrows its current pot.

Life cycleYucca filamentosa 'Bright Edge', also known as Adam's needle, begins its life cycle as a seed, which germinates in well-draining soil with full sunlight exposure. As a seedling, it develops long, sword-shaped leaves with distinctive yellow margins and a rough texture. Over several years, the plant forms a rosette, thickening with more leaves and establishing a strong root system. Adult Adam's needle may produce tall flower stalks, up to 6 feet high, with a panicle of creamy white bell-shaped flowers, usually in the summer. After flowering, seed pods develop, which eventually dry and release seeds for reproduction. Adam's needle is a perennial plant, capable of living for many years, and over time the clumps can be divided to propagate new plants.
PropogationPropogation time
Spring-Early Summer
Propogation: The most popular method of propagation for the Yucca filamentosa 'Bright Edge', commonly known as Adam's needle, is by division. This is ideally done in the spring as the plant emerges from dormancy. The process involves digging up the parent plant and gently separating the offshoots, or "pups," which are smaller plants that grow at the base of the mature plant. These pups usually have their own roots and can be carefully cut away from the main plant using a clean, sharp knife. Once separated, the pups should be planted in well-draining soil, maintaining the same depth at which they were previously growing. It is important to water the new plants thoroughly after planting to help establish their root systems.
