Curlyleaf Yucca

About this plant

Yucca filamentosa 'Excalibur' is a superb, evergreen perennial known for its rosette of stiff, sword-like leaves that feature attractive, curling white filaments along their margins. This cultivar is particularly prized for its compact form and impressive flower stalks. In late spring to early summer, towering flower stalks emerge, reaching several feet high and bearing a magnificent display of creamy white, bell-shaped flowers. These blossoms attract pollinators and add an elegant vertical element to any garden design. 'Excalibur' Curlyleaf Yucca is an excellent choice for xeriscaping, rock gardens, borders, or as a focal point in contemporary and drought-tolerant landscapes. Its unique texture and form provide year-round interest.

Installation timing

When we're in season, outside of the winter months, our goal is to get your plants installed within about two weeks. That window gives us enough time to secure your plants from our supplier and find a spot on the schedule. Throughout the process we stay in touch through notifications and your existing client portal on the main A Cut Above website, which is separate from this landscaping plants shop.

Care & maintenance

Extremely low maintenance. Requires minimal care once established. Remove spent flower stalks after blooming. Protect from excessive winter moisture in poorly drained soils.

Watering suggestions

Proper watering is the single most important factor in your plant's survival after installation. Newly installed plants have a limited root system and rely on you for consistent moisture while they establish.

• First 2 weeks: Water deeply every day (or every other day in cooler, wet weather), soaking the root ball and surrounding soil.
• Weeks 3–12: Water deeply 2–3 times per week, adjusting for rain, heat, and soil drainage.
• After establishment: Water deeply about once a week during the growing season, and more often in extreme heat or drought.
• How to check: Stick a finger 2–3 inches into the soil near the roots — if it's dry, it's time to water. Deep, less-frequent watering encourages strong roots; shallow daily sprinkles do not.
• Avoid: Overwatering (soggy, waterlogged soil) is just as harmful as underwatering and can drown roots.

Watering needs vary by plant, season, soil, and exposure. Because proper watering is the customer's responsibility after installation, please make sure you understand and can follow these suggestions before ordering.

Good to know: plants and trees purchased from and installed by A Cut Above include a one-year limited warranty from the date of installation. Because plant survival depends heavily on proper watering and care after installation, losses caused by improper care, neglect, animal or chemical damage, or extreme weather are not covered, and we must be given the chance to inspect a struggling plant before it's removed or replaced. Coverage is one replacement per plant. Read our warranty info.
