Eryngium agavifolium High Humidity Hardiness: borderline (around RHS H3)The Eryngium agavifolium, or agave leaved sea holly, is one of the most striking architectural perennials you can grow for a hot, sunny border. 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.
