Yucca 'Silver Anniversary' is a Tony Advent introduction in 2018 that was the result of crossing the two North American species, the Adam's needle, Yucca filamentosa and the Pale-leaf Yucca, Yucca pallida. This resulting seedling from the Yucca breeding program conducted by Tony at his Plant Delights Nursery in Raleigh, N.C. began in 2013, twenty-five years after the nursery was founded in 1988. With this timing in mind and this plants silver-gray foliage in mind, 'Silver Anniversary' is a very fitting name! Of its parents, this plant looks more similar to Yucca pallida but seems to have gained vigor from the Yucca filamentosa parent.
This plant is marketed in the US by PlantHaven and we were asked to trial it in 2019. It received US Plant Patent PP31,437 in February 2022. The pictures of it on this website were provided by PlantHaven.
