Yucca Excalibur
Yucca filamentosa 'Excalibur'
Yucca Excalibur is one of those plants that gives you a lot of visual impact without asking for much in return. I like the blue-gray foliage because it feels cleaner and more refined than a standard green yucca, and the compact habit makes it easier to use in modern beds, rock gardens, and tight sunny borders. For homeowners looking for a drought-tolerant evergreen accent, a deer-resistant plant for tough sites, or a bold architectural focal point with white summer flowers, this is a really smart choice.

A Bold Blue-Gray Yucca With Year-Round Structure And Summer Flower Spikes
Blue-Gray Foliage That Adds Instant Architectural Interest
Yucca Excalibur is the kind of plant that gives a garden a clean, sculptural look the moment it goes in the ground. Its stiff sword-like leaves form a dense rosette with a strong blue-gray cast that stands out beautifully against green shrubs, gravel mulch, stone, and flowering perennials. That cool-toned foliage gives it a more refined and modern look than a standard green yucca, making it especially useful in contemporary landscapes and water-wise plantings.
Because the foliage is evergreen, the plant continues to produce long after bloom season has passed. It adds strong texture year-round and helps anchor dry borders, rock gardens, and sunny foundation beds with a crisp, organized presence. For homeowners looking for an evergreen accent plant that delivers bold form without high maintenance, Yucca Excalibur is an excellent choice.
A Compact Habit That Works Well In Smaller Landscapes
One of the biggest advantages of Yucca Excalibur is that it offers the toughness of yucca in a tidier, more compact form. It stays lower and more uniform than many older types, which makes it easier to use in smaller beds, tighter garden borders, and designed landscapes where every plant needs to earn its space. The rounded rosette shape gives the plant a finished appearance even when it is not flowering.
That smaller habit makes it especially effective as a specimen in gravel gardens, at the front of sunny mixed borders, or repeated in groups for a stronger visual rhythm. It is also a smart choice when a homeowner wants the drama of a yucca without committing to something oversized or overly wild-looking. This plant has a strong structure, but it still feels polished.
Tall White Flower Spikes Bring A Summer Accent
In summer, mature plants send up tall flower stalks topped with clusters of creamy white bell-shaped blooms. Those flower spikes rise well above the foliage and add a strong vertical accent to the planting, making the plant even more dramatic in bloom. The flowers also attract pollinators, which gives the plant added garden value beyond its strong structural role.
Even after the flowers fade, the plant retains its ornamental value, as the blue-gray foliage remains the main attraction. Spent stalks can simply be removed at the base once bloom is over, helping the plant direct energy back into its evergreen rosette. For gardeners who want a drought-tolerant plant with both foliage interest and a seasonal bloom moment, Yucca Excalibur delivers both.
A Tough, Low-Water Plant For Full Sun Landscapes
Yucca Excalibur thrives in full sun and well-drained soil, making it an ideal fit for xeriscaping, rock gardens, dry borders, coastal plantings, and other hot, exposed sites. Once established, it is highly drought-tolerant and also resists deer, many pests, and tough growing conditions that challenge softer-textured plants. It is the kind of plant that looks striking while asking for very little in return.
This makes it especially appealing to busy homeowners and those seeking low-maintenance landscapes. Give it sunshine, drainage, and restraint with watering, and it settles in as a long-lived evergreen accent with year-round presence. For homeowners looking for a deer-resistant yucca, a blue-gray evergreen focal point, or a tough plant for dry sunny sites, Yucca Excalibur is a standout choice.

How to Care for Yucca Excalibur
Before purchasing your Yucca 'Excalibur', be sure to read the recommended care instructions to ensure your plant remains happy and healthy for years to come!
How should I plant Yucca Excalibur?
Plant Yucca Excalibur in a location with full sun and very well-drained soil. It performs especially well in sandy, rocky, or lean soils and is a great choice for xeriscapes, gravel gardens, and sunny borders where drainage is excellent. Dig a hole about twice as wide as the root ball but no deeper than the root ball itself so the crown does not end up buried too deeply. Backfill with native soil and avoid over-amending if the site already drains well. Water thoroughly after planting, then allow the soil to begin drying between waterings as the roots settle in. In heavier soils, improving drainage is much more important than adding rich organic matter.
How often should I water Yucca Excalibur after planting?
Water Yucca Excalibur regularly during establishment to help the roots settle in, but do not keep the soil constantly wet. Deep watering once a week is usually enough in average conditions, with adjustments for heat, rainfall, and soil type. The key is to let the soil dry somewhat between waterings because yuccas dislike soggy conditions. Once established, Yucca Excalibur becomes highly drought-tolerant and usually needs only occasional supplemental watering during extended dry periods. Overwatering is much more likely to cause problems than underwatering, especially in containers or heavier soils.
When should I fertilize Yucca Excalibur?
Yucca Excalibur generally needs only light feeding. In spring, a balanced slow-release fertilizer can be applied to support healthy growth and maintain strong foliage color. One light application per year is usually enough for this low-maintenance plant. Avoid heavy fertilizing, since rich feeding is unnecessary for a plant adapted to leaner conditions. In many landscapes, good drainage and full sun matter more than fertilizer when it comes to long-term performance.
When and how should I prune Yucca Excalibur?
Yucca Excalibur needs very little pruning. Once flowering is complete, cut the spent flower stalk back to the base to keep the plant looking tidy and help direct energy back into the foliage rosette. Wear gloves when pruning because the leaves are stiff and pointed. You can also remove any damaged or older outer leaves as needed, but avoid cutting into the plant's center. Minimal cleanup is usually all that is required to keep it looking strong and architectural.
