Hesperaloë parviflora

This is Hesperaloë parviflora, the so-called red yucca. It's blooming here this year for the first time. It began to bloom back in June, and it's still producing flowers. The individual flowers are about the size and color of those of Fritillaria recurva, but otherwise it looks like nothing else in the garden. The flowers look as if they had been carved from coral itself or some coral colored mineral of the cryptocrystalline quartz group. And the inflorescence is tall: it got to be over six feet high.
