Re: Yucca blooms are emerging..............
great to see that hybrid blooming in your garden! I have a Y. fila 'Tenn' x 'reverchonii-thompsoniana' in my garden too. Mine looks slightly different from yours as mine has slightly narrow leaves and it's blue-er in color. Mine has not bloomed yet, so I'm jealous!
Mine can be seen at the base of the Y. elata (look on the right side of trunk). It's not blooming, the bloom is on a Y. stricta behind it.
