Summary
A bold, sculptural yucca that anchors dry landscapes with striking blue foliage.
Yucca rigida ‘Blue Sentry’ forms a dense rosette of stiff, sword-like leaves that mature into a strong, upright presence. The powder-blue coloration intensifies in full sun and dry conditions, making it especially effective in xeriscapes and gravel gardens.
In early to mid-summer, tall flower spikes rise above the foliage carrying clusters of creamy white blooms. Its evergreen structure provides year-round architectural interest in suitable climates.
Care
Blue Sentry Yucca Care
Plant in Full Sun for best color and structure. Well-drained soil is essential, particularly in winter.
Suitable for sandy, rocky, or gravelly soils. Avoid heavy, poorly drained clay unless amended for drainage.
Water regularly during establishment. Once established, allow soil to dry between waterings. This variety is highly drought tolerant in mature plantings.
Fertilization is rarely required, but if desired, apply slow release fertilizer in early spring.
Remove spent flower stalks after blooming to maintain a clean appearance.
Container Growing: Use a large container with excellent drainage and a gritty, fast-draining mix. Container-grown plants require more frequent watering than those planted in the ground and may need winter protection in colder zones.
