Description

Yucca flaccida ‘Blue Sentry’ (Blue Sentry Adam’s Needle) is an evergreen, architectural yucca cultivar prized for its dramatic blue-gray, sword-like leaves framed by a narrow yellow margin, forming a compact rosette up to ~3 feet across. In summer, it sends up 4–6 ft tall stalks of creamy-white, bell-shaped flowers that attract yucca moths and pollinators. Origins trace to selections of Y. rigida/native Y. flaccida, though expert sources (Plant Delights) suggest potential Y. rigida heritage; it thrives in USDA Zones 5a–9b and is notably drought‑tolerant, deer‑resistant, and long-lived.

Striking powder‑blue, narrow, leathery evergreen leaves with yellow margins, forming a neat, symmetrical rosette.
Summer blooms: sturdy 4–6 ft spikes of creamy-white, bell-shaped flowers that attract pollinating moths and bees.
Exceptionally hardy (Zones 5–9), extremely drought and deer resistant, thriving in poor, hot, sunny sites.
