Rainy Side Notes

Looking like an agave with teeth, this new world plant's natural habitat is on stony hills and riverbanks of Argentina. Since we cannot grow agaves in our maritime Pacific Northwest climate without protecting it over winter, this agave-like plant is a hardy alternative.

In summer, E. agavifolium throws up tall stalks of flowers that can be cut for the vase or for drying. Many prefer just the foliage and cut the flower stalks off. After being poked by its jagged teeth a few times, I am not sure I prefer the foliage! Christopher Lloyd proclaimed, "It is a bold plant but coarse in a rather unpleasant way." I wonder if he was poked by it, too?
