It forms a bold evergreen rosette of long, sword-shaped leaves edged with sharp, agave-like teeth, and in summer it sends up branched stems topped with cylindrical, greenish-white thimble flowerheads. The effect is pure structure, a fountain of spiky foliage crowned by cool green cones that hold for weeks.\u003c\/p\u003e\u003cp\u003eNative to Argentina and rated RHS H4, it is hardy across most of the UK, shrugging off temperatures to around -10C once established given sharp drainage. Because the rosette is evergreen it earns its place all year, keeping form through winter when so much of the border has died back.
