If I were a poet, I'd write an ode to Cardiocrinum giganteum (Giant Himalayan Lily). It took my breath away this year. I nicknamed it "Angel of Death" (thanks to Amanda for the idea) because of its location in the devil garden, angelic white blooms towering on high, and also because it dies after a multi-year march to flowering. Since I'm not a poet, I'm just offering some basic documentation here. I planted this bulb in 2013, it was part of the initial devil garden planting. It must have been several years old already.
March 22nd of this year, newly sprouting again, already with gorgeous leaves.
