Blue Sentry Yucca

Blue Sentry (Yucca rigida 'Blue Sentry') is a slow, upright yucca with rigid leaves that shift from blue to powder blue and carry narrow yellow margins. Creamy bell flowers rise above the foliage as the plant matures. ## Garden Placement The [Briggs Nursery profile](https://www.briggsnursery.com/plant/yucca-rigida-blue-sentry/) recommends full sun and alkaline, well-drained soil. Its profile lists a mature size of 10 feet tall by 5 feet wide; the description notes that plants are more often 4–5 feet tall before reaching their taller form with age. It also describes the flowers as pollinator-friendly. ## Growing Conditions Blue Sentry resists drought after establishment and tolerates a range of conditions. A little supplemental water in summer can support a stronger flower display; keep the soil draining freely. ## Maintenance Allow room for the upright rosette and its eventual flower stalk. Limit irrigation after establishment and avoid moving the plant once it is settled.
