Nolina Longifolia.
The Nolina Longifolia is highly attractive, with dense crowns of long gracefully flowing soft green leaves, much less rigid than many other Nolinas. Leaves are finely serrated. Very slow growing as they mature they eventually form an amazing stout, corky textured trunk. Large flower spikes can reach 5-6ft in height above the foliage, but only appear when the plant has reached advanced maturity.

This is a exceptionally beautiful plant and very showy, great for providing architectural interest, but also easy to maintain. Can also work well as an indoor plant
