Yucca filamentosa x pallida 'Silver Anniversary’

Yucca filamentosa × pallida ‘Silver Anniversary’: Dusty-Blue Rosettes with Burgundy Spring Spires

Yucca ‘Silver Anniversary’ is a bold, architectural accent that looks sharp and intentional from the moment it emerges in spring. Rigid, dusty-blue, sword-like foliage forms a handsome clump, then in mid-May, dramatic flower spikes rise high above the leaves, emerging a rich burgundy before opening to pendulous white, bell-shaped blooms. The contrast is striking in full sun, and the plant’s strong form holds its own even when not in flower. Once established, it handles heat and dry spells with confidence, making it a standout for low-fuss, high-impact planting.

Plant Characteristics:

• Height: 60 cm (foliage), flower spikes to 210 cm
• Spread: 120 cm
• Flower Colour: White
• Flowering Period: Late spring to early summer
• Foliage: Rigid, dusty-blue, sword-like foliage
• Sunlight Requirements: Full sun
• Soil Requirements: Well-drained soil

Uses and Benefits: Use ‘Silver Anniversary’ as a strong focal point in sunny borders, gravel gardens, and modern foundation plantings where clean lines and bold texture matter. Its cool blue foliage adds contrast to greener plantings, while the tall flower stalks bring instant vertical drama in late spring. It is especially effective near patios or pathways where the bloom spikes can be appreciated up close, and it shines in repeated plantings that create rhythm and structure through the landscape.

Care Instructions: Plant in full sun with excellent drainage, and avoid sites that stay wet, especially in winter. Water regularly during the first growing season to establish, then water only during prolonged drought. In heavier soils, amend to improve drainage or use a gravelly planting mix. Remove spent flower stalks after blooming, and tidy any winter-worn leaves in spring to refresh the clump.

History: This hybrid combines the rugged durability of Yucca filamentosa with the refined, glaucous tones associated with Yucca pallida. ‘Silver Anniversary’ is prized for its dusty-blue foliage and its distinctive burgundy flower spikes, offering a more dramatic, design-forward look than many traditional yuccas.

Final Thoughts: If you want a sun-loving plant that looks crisp all season and delivers a true spring statement, ‘Silver Anniversary’ brings cool blue foliage and towering bloom spikes that make the whole planting feel more intentional.
